Question 1Reading
A passage states that a city council approved a budget 'unanimously.' A reader wants to confirm what that word means in this context. Which reference source is most appropriate for that purpose?
- A style manual section on capitalization
- An atlas index of the city
- A thesaurus listing synonyms only
- A dictionary entry for 'unanimously' Correct answer.
Explanation
A dictionary provides the meaning of a word, which is exactly what the reader needs to interpret 'unanimously' as showing full agreement. The other sources address geography, word substitution, or formatting conventions rather than definition.
Question 2Reading
In a passage about honeybees, the writer explains that workers 'communicate the location of flowers through a waggle dance.' What is the main idea this sentence supports?
- Bees live in colonies with one queen
- Bees prefer flowers of a single color
- Bees build hives from wax
- Bees use movement to share foraging information Correct answer.
Explanation
The sentence directly describes a method of communication, so the idea it supports is that bees convey foraging information through movement. The other choices name true bee facts but are not what this sentence is developing.
Question 3Reading
A paragraph begins: 'Although the new bridge shortened commutes, it also diverted traffic from downtown shops.' Which organizational pattern does this sentence establish?
- Definition supported by examples
- Cause followed by a single effect
- Chronological sequence of events
- Comparison of advantages and disadvantages Correct answer.
Explanation
The word 'although' signals a contrast between a benefit and a drawback, which sets up a comparison of pros and cons. Chronology, simple causation, and definition are not signaled by this construction.
Question 4Reading
Read this sentence: 'The committee reviewed the proposal carefully before voting.' Which word functions as an adverb?
- proposal
- committee
- carefully Correct answer.
- before
Explanation
An adverb modifies a verb, adjective, or another adverb; 'carefully' describes how the committee reviewed. 'Committee' and 'proposal' are nouns, and 'before' here introduces a time relationship as a preposition or conjunction.
Question 5Reading
A student reads a science article and must identify the author's attitude toward a new pesticide. Which feature of the text best reveals that attitude?
- Word choices such as 'promising' or 'reckless' Correct answer.
- The length of the article's title
- The number of paragraphs in the article
- The presence of a publication date
Explanation
Tone and attitude are conveyed through connotative word choice, so evaluative adjectives like 'promising' or 'reckless' reveal the author's stance. Structural features such as paragraph count, title length, and dates do not express attitude.
Question 6Reading
Which sentence uses a colon correctly to introduce a list within an academic paragraph?
- The lab requires: goggles, gloves, and a notebook for each student.
- The lab requires three supplies: goggles, gloves, and a notebook. Correct answer.
- The lab requires three supplies, goggles: gloves, and a notebook.
- The lab requires three supplies; goggles: gloves, and a notebook.
Explanation
A colon introducing a list should follow a complete independent clause, and 'The lab requires three supplies' is complete. The other versions place the colon after an incomplete clause or interrupt the list incorrectly.
Question 7Reading
A reader encounters the unfamiliar word 'arid' in a passage about deserts and notes that the surrounding sentences describe cracked soil and scarce rainfall. Which strategy is the reader using?
- Skimming for the topic sentence
- Evaluating the author's bias
- Scanning for a date
- Using context clues to infer meaning Correct answer.
Explanation
Drawing meaning from surrounding details such as cracked soil and little rain is the use of context clues. Skimming, scanning, and bias evaluation serve different reading purposes and do not derive a word's meaning from nearby text.
Question 8Reading
In the sentence 'The researchers published their findings after the peer review concluded,' what is the simple subject?
- concluded
- findings
- review
- researchers Correct answer.
Explanation
The simple subject is the noun performing the action of the verb 'published,' which is 'researchers.' 'Findings' is the object, 'review' appears in a prepositional phrase, and 'concluded' is a verb.
Question 9Reading
A passage notes that a study found a correlation between library visits and test scores, then warns that other factors may explain the link. What is the author doing in the warning?
- Cautiously limiting the conclusion drawn from the data Correct answer.
- Contradicting the study's published results
- Introducing an unrelated personal anecdote
- Rejecting the value of libraries entirely
Explanation
By noting confounding factors, the author qualifies how much the correlation can prove, which is a cautious limitation. The warning does not deny the results, dismiss libraries, or shift to anecdote.
Question 10Reading
Which transition best fills the blank? 'The first trial produced inconclusive results; _____, the team redesigned the experiment.'
- however
- similarly
- therefore Correct answer.
- meanwhile
Explanation
The redesign is a consequence of the inconclusive results, so a cause-and-effect transition such as 'therefore' fits. 'However' signals contrast, 'similarly' signals likeness, and 'meanwhile' signals concurrent time.
Question 11Reading
A passage presents statistics from three studies, then states: 'Taken together, these findings suggest that early reading habits predict later academic success.' This statement is best described as:
- A direct quotation from a single source
- A primary-source data table
- An unsupported personal opinion
- A synthesis drawing a conclusion from multiple sources Correct answer.
Explanation
Combining evidence from several studies into one conclusion is synthesis. The statement is not a quotation, a data table, or an unsupported opinion because it rests on the cited studies.
Question 12Reading
A reader must determine whether a website article about nutrition is reliable. Which evidence most strongly supports its credibility?
- The article uses an informal, friendly tone
- The article was shared widely on social media
- The article includes several colorful photographs
- The article cites peer-reviewed studies and names their authors Correct answer.
Explanation
Credibility is best supported by citations to peer-reviewed research with identifiable authors, which allows verification. Photographs, popularity, and tone do not establish accuracy.
Question 13Reading
Read this sentence: 'Having finished the experiment, the results were recorded by the student.' What is the sentence's structural problem?
- The passive voice is grammatically impossible here
- The sentence contains a comma splice
- The verb tense shifts incorrectly within the clause
- A dangling modifier leaves 'having finished' without a clear subject Correct answer.
Explanation
The introductory participial phrase should modify the person who finished the experiment, but the main clause subject is 'results,' creating a dangling modifier. A splice, impossible passive, or tense error is not the issue.
Question 14Reading
An author writes: 'Requiring uniforms may reduce distractions, but students also need room to express themselves.' Which claim does the author ultimately support?
- Ignoring the question of distraction entirely
- The complete elimination of dress codes
- A strict uniform mandate without exceptions
- A balanced policy that weighs both order and self-expression Correct answer.
Explanation
The sentence acknowledges a benefit of uniforms while insisting on self-expression, which points to a balanced position. The author does not endorse a strict mandate, abolish dress codes, or dismiss distraction.
Question 15Reading
Which sentence correctly uses a semicolon in an academic essay?
- The data were incomplete; the researchers repeated the trial. Correct answer.
- The data were incomplete; because the trial failed.
- The data were incomplete; and the researchers repeated the trial.
- The data were incomplete; repeating the trial.
Explanation
A semicolon can join two closely related independent clauses, and both sides of this sentence are complete. The others pair the semicolon with a conjunction, a dependent clause, or a fragment.
Question 16Reading
A passage describes a character who 'spoke softly and avoided eye contact, though her hands never stopped moving.' What inference about the character is best supported?
- She is bored by the conversation
- She feels uneasy despite trying to appear calm Correct answer.
- She is angry at the people around her
- She is confident and eager to lead
Explanation
Quiet speech and averted eyes suggest discomfort, while restless hands hint at concealed tension, supporting an inference of unease. Anger, boredom, and confidence are not supported by these details.
Question 17Reading
A student needs to locate the specific page where a book discusses 'photosynthesis in desert plants.' Which approach is most efficient?
- Consult the book's index for the relevant terms Correct answer.
- Check the book's copyright date
- Review the table of contents only
- Read the book from the first chapter onward
Explanation
An index lists terms with page numbers, making it the fastest route to a specific topic. Sequential reading is slow, a copyright date gives no content location, and a table of contents is too general for a narrow topic.
Question 18Reading
What is the primary purpose of a paragraph's topic sentence in an expository passage?
- To summarize the entire document's conclusion
- To state the paragraph's central point that the details develop Correct answer.
- To provide a transition to the previous chapter
- To quote an expert source verbatim
Explanation
A topic sentence announces the main idea of its paragraph, which the supporting sentences then explain or illustrate. It is not primarily a chapter transition, a quotation, or a summary of the whole document.
Question 19Reading
An article claims a new study 'proves' a diet prevents illness, but the study involved only twelve participants over two weeks. Which critique is most reasonable?
- The study should have used a different font in its report
- The claim is valid because the word 'proves' is used
- Participant number is irrelevant to study strength
- The sample is too small and short to support such a strong claim Correct answer.
Explanation
A small, brief study cannot justify a sweeping causal claim, so questioning the sample size and duration is a sound critique. Formatting is irrelevant, and neither the wording nor dismissal of sample size strengthens the claim.
Question 20Reading
In the sentence 'Neither the students nor the teacher was aware of the schedule change,' which rule explains the verb 'was'?
- With 'neither...nor,' the verb agrees with the nearer subject Correct answer.
- The verb agrees with the first subject listed
- The verb form is chosen to match the object
- Plural subjects always take a singular verb
Explanation
In a 'neither...nor' construction, the verb agrees with the subject closest to it, which is the singular 'teacher,' so 'was' is correct. The other rules misstate subject-verb agreement.
Question 21Reading
A passage states: 'The museum's new wing, funded entirely by private donors, opened last spring.' Which detail is a nonessential modifier?
- the museum
- funded entirely by private donors Correct answer.
- opened last spring
- The museum's new wing
Explanation
The phrase set off by commas adds extra information about funding and can be removed without changing the core meaning, making it a nonessential modifier. The remaining elements are the subject and predicate of the main clause.
Question 22Reading
An author writes that a policy 'has been called innovative by some and reckless by others' before presenting evidence for one view. What is the effect of this framing?
- It replaces the need for supporting evidence
- It acknowledges opposing views before the author argues a position Correct answer.
- It proves that the policy is objectively reckless
- It shows the author has no opinion on the policy
Explanation
Presenting both labels before arguing signals that the author recognizes competing perspectives while still building a case. It does not establish recklessness, erase the author's stance, or substitute for evidence.
Question 23Reading
A reader compares two articles on the same topic: one cites primary documents, the other cites only anonymous blog posts. Which conclusion about relative reliability is best supported?
- The article with primary documents is generally more verifiable Correct answer.
- Neither article can be evaluated without reading the author's biography
- The blog-based article is more reliable because blogs are current
- Both articles are equally reliable regardless of sources
Explanation
Primary documents can be checked and traced, which makes claims more verifiable than anonymous blog posts. Recency does not guarantee accuracy, sources do affect reliability, and an author's biography is not required to assess citations.
Question 24Reading
Read this sentence: 'The report, which the committee reviewed twice, was revised.' Which type of clause is 'which the committee reviewed twice'?
- An adverbial clause of condition
- A nonrestrictive relative clause Correct answer.
- An independent clause
- A restrictive relative clause
Explanation
The clause is set off by commas and adds nonessential information about the report, making it a nonrestrictive relative clause. It is dependent, not independent, and it does not express a condition.
Question 25Reading
A passage argues: 'Cities that added bike lanes saw a rise in cycling. Therefore, bike lanes cause more people to cycle.' Which assumption underlies this conclusion?
- Cycling was already declining before the lanes were added
- Bike lanes are always popular with drivers
- The cities studied had identical weather
- No other factor, such as new bike-share programs, caused the rise Correct answer.
Explanation
To move from correlation to causation, the author must assume that no alternative explanation accounts for the increase. Prior decline, driver opinion, and identical weather are not necessary assumptions for the causal claim.
Question 26Reading
A student reading a textbook chapter on volcanoes encounters the sentence 'The magma chamber, though dormant for centuries, remained pressurized.' Which context clue most directly helps the student infer the meaning of 'dormant'?
- The capitalization of 'The' at the sentence start shows importance.
- The word 'magma' signals that the term relates to geology.
- The word 'chamber' indicates a physical enclosed space.
- The phrase 'though dormant for centuries' contrasts with 'remained pressurized,' suggesting inactivity. Correct answer.
Explanation
Contrast clues use words like 'though' to set up an opposition between two ideas. Here the dormant state is set against the chamber remaining pressurized, so 'dormant' points to inactivity rather than activity.
Question 27Reading
A reader wants to evaluate whether an online article about a new medical treatment is credible. Which feature of the article provides the strongest evidence of reliability?
- The article includes several emotional patient testimonials.
- The article includes a list of peer-reviewed sources with authors and publication dates. Correct answer.
- The article uses bold headings and bullet points for readability.
- The article was shared frequently on social media.
Explanation
Reliability in academic reading rests on verifiable, authoritative sourcing. Citations with named authors and dates let a reader check the evidence independently. Formatting, popularity, and anecdotes do not establish accuracy.
Question 28Reading
In the sentence 'The committee reviewed the proposal carefully before the deadline,' which word functions as the adverb modifying the verb?
- carefully Correct answer.
- committee
- deadline
- proposal
Explanation
An adverb modifying a verb answers how, when, or where the action occurred. 'Carefully' tells how the committee reviewed, so it is the adverb. The other words are nouns.
Question 29Reading
A paragraph in an expository essay opens with: 'Urban trees provide measurable economic benefits.' The next sentences give data on energy savings and property values. What is the function of the opening sentence?
- It introduces a counterargument the paragraph will refute.
- It offers a specific example of a broader claim.
- It states the paragraph's main idea, which the following details support. Correct answer.
- It provides a transition from the previous paragraph only.
Explanation
A topic sentence states the controlling idea of a paragraph, and the supporting sentences supply evidence for it. The energy and property data elaborate on the economic-benefit claim.
Question 30Reading
A student is reading a persuasive passage and wants to identify the author's claim. Which sentence from the passage most likely states the claim rather than supporting evidence?
- One district that delayed start times saw attendance rise by four percent.
- School start times should be delayed because adolescent sleep patterns require later wake times. Correct answer.
- Sleep researchers note that melatonin release shifts later during adolescence.
- A 2019 survey of 3,000 students reported average bedtimes after 11 p.m.
Explanation
The claim is the debatable position the author wants the reader to accept, often signaled by 'should.' The other sentences present survey data, a case result, and expert findings that support it.
Question 31Reading
In the sentence 'The auditorium, along with the adjacent classrooms, requires renovation,' which rule explains the singular verb 'requires'?
- The verb agrees with the nearest noun, 'classrooms.'
- The phrase 'along with' makes the subject plural.
- The verb is singular because the sentence is in the passive voice.
- The subject is 'auditorium'; the phrase 'along with the adjacent classrooms' does not change the subject's number. Correct answer.
Explanation
Interrupting phrases such as 'along with' or 'as well as' do not alter the grammatical number of the subject. The true subject is the singular 'auditorium,' so the verb must be singular.
Question 32Reading
A reader encounters the pronoun 'they' in a passage and must determine what it refers to. Which strategy is most reliable for resolving the reference?
- Replace 'they' with the first noun in the entire passage.
- Skip the pronoun since it carries no meaning.
- Assume 'they' always refers to the author's intended audience.
- Look to the preceding sentence for the most recent matching plural noun that fits the meaning. Correct answer.
Explanation
Pronoun reference is typically resolved by finding the nearby antecedent whose number and sense fit the context. Checking meaning guards against choosing a grammatically possible but illogical referent.
Question 33Reading
An author writes: 'Although the new policy reduced paperwork, it introduced delays that frustrated staff.' Which tone does the sentence convey toward the policy?
- Wholly enthusiastic and uncritical
- Neutral to the point of providing no evaluation
- Balanced, acknowledging both a benefit and a drawback Correct answer.
- Openly hostile with no recognition of benefits
Explanation
The concessive 'although' grants a positive effect before presenting a negative one. This structure signals a balanced, qualified assessment rather than pure praise or pure criticism.
Question 34Reading
A passage states: 'The experiment failed to confirm the hypothesis; _____, the researchers gained insight into an unexpected variable.' Which transition best completes the sentence?
- for instance
- therefore
- similarly
- however Correct answer.
Explanation
The two clauses contrast a negative result with a positive outcome, so a contrast transition is required. 'However' signals that opposition between the clauses.
Question 35Reading
A reader is summarizing an argumentative passage and must distinguish the author's conclusion from the premises. Which element is the conclusion?
- The opposing viewpoint quoted before the rebuttal
- The definition of a key term given in the introduction
- The statistical data cited in the second paragraph
- The statement the author wants the reader to accept, supported by the other statements Correct answer.
Explanation
In an argument, the conclusion is the claim being argued for, and premises are the reasons offered in its support. Data, definitions, and opposing views function as support or context.
Question 36Reading
A textbook passage explains a process using the words 'first,' 'next,' 'meanwhile,' and 'finally.' Which organizational pattern does the passage primarily use?
- Sequential or chronological order Correct answer.
- Problem and solution
- Cause and effect
- Comparison and contrast
Explanation
Sequential markers such as 'first,' 'next,' and 'finally' arrange information by steps or time. Recognizing these signals helps a reader follow the structure of a process explanation.
Question 37Reading
A student reads two passages on the same event. Passage A was written the day after by a journalist; Passage B was written ten years later by a historian using archives. Which statement best describes a likely difference between them?
- Passage B may offer broader context and reflection, while Passage A may capture immediate reactions. Correct answer.
- Passage B is unreliable because historians were not present at the event.
- Passage A is automatically more accurate because it is closer in time.
- Both passages must contain identical facts since they describe the same event.
Explanation
Timing and source type shape perspective: immediate reporting tends to capture fresh reactions, while later historical work can synthesize archives and provide context. Neither is automatically superior in accuracy.
Question 38Reading
In the sentence 'The scientist who discovered the enzyme received the award,' what is the function of the clause 'who discovered the enzyme'?
- It is an independent clause that could stand alone.
- It is a nonessential clause set off by commas.
- It is an adverbial clause modifying 'received.'
- It is an essential relative clause that identifies which scientist is meant. Correct answer.
Explanation
A relative clause beginning with 'who' modifies the noun 'scientist.' Without commas, it is restrictive, meaning it is necessary to identify the specific scientist.
Question 39Reading
A paragraph contains this sentence: 'The data was collected over six months and then analyzed.' In formal academic writing, which revision corrects the agreement issue?
- The datas were collected over six months and then analyzed.
- The data is collected over six months and then analyzed.
- The data were collected over six months and then analyzed. Correct answer.
- The data was being collected over six months and analyzed.
Explanation
In formal academic usage, 'data' is the plural of 'datum,' so it takes a plural verb such as 'were.' The revision also keeps the parallel past-tense verbs 'collected' and 'analyzed.'
Question 40Reading
A reader wants to determine the author's purpose in a passage that describes a city's new recycling program, lists its costs and benefits, and ends without urging any action. Which purpose is most likely?
- To persuade readers to oppose the program
- To inform readers by presenting an objective overview Correct answer.
- To instruct readers step by step in recycling at home
- To entertain readers with an amusing story
Explanation
Presenting costs and benefits without a call to action signals an informative purpose. Persuasive writing urges a position, while instructive writing gives procedural steps.
Question 41Reading
A passage uses the word 'novel' in the sentence 'The team proposed a novel method for filtering water.' Which meaning of 'novel' is intended here?
- A work of fiction
- Widely criticized
- Long-established
- New and original Correct answer.
Explanation
Multiple-meaning words must be resolved by context. Because 'novel' modifies 'method' in a scientific description, it means new or original rather than a fictional narrative.
Question 42Reading
An essay's introduction ends with: 'This paper will examine how two urban planning models address housing shortages.' Which reading strategy does this sentence best support?
- Setting a purpose by predicting the passage's focus and organization Correct answer.
- Memorizing the passage word for word
- Evaluating the passage's publication date
- Identifying the author's emotional bias
Explanation
A thesis or purpose statement tells the reader what to expect and how the discussion will be organized. Using it to predict focus is an active reading strategy that improves comprehension.
Question 43Reading
A writer wants to combine these sentences: 'The bridge was closed. The storm had damaged its supports.' Which revision best shows the cause-effect relationship?
- The bridge was closed; the storm had damaged its supports.
- The bridge was closed because the storm had damaged its supports. Correct answer.
- The bridge was closed although the storm had damaged its supports.
- The bridge was closed, and the storm had damaged its supports.
Explanation
A causal relationship is expressed most clearly with a subordinating conjunction such as 'because.' The other versions either merely coordinate the clauses or signal the wrong logical relationship.
Question 44Reading
A reader notices that a passage repeatedly uses the phrase 'studies show' without naming any studies. How should this affect the reader's evaluation of the passage?
- It proves the passage is fictional.
- It weakens credibility because the evidence cannot be verified. Correct answer.
- It has no effect because the phrase is common in writing.
- It strengthens credibility because repetition signals certainty.
Explanation
Vague appeals to unnamed studies cannot be checked, so they provide weak support for claims. Critical readers look for specific, verifiable citations before accepting evidence.
Question 45Reading
A paragraph reads: 'Many assume that multitasking improves productivity. Research on task switching, however, shows that it increases errors and completion time.' Which technique does the author use to develop the point?
- Comparing two equally valid viewpoints without preference
- Defining a technical term through examples
- Presenting a chronological sequence of events
- Refuting a common assumption with research evidence Correct answer.
Explanation
The paragraph states a popular belief and then counters it with research findings. This refutation structure uses evidence to overturn an assumption rather than to narrate or define.
Question 46Reading
A passage contains the sentence: 'The proposal, having been rejected twice, was finally approved.' Which statement accurately describes the sentence's structure?
- The main clause is 'The proposal was finally approved,' and the participial phrase modifies 'proposal.' Correct answer.
- The phrase 'having been rejected twice' functions as the subject.
- The sentence contains two independent clauses joined by a comma.
- The main clause is 'having been rejected twice,' and the rest is subordinate.
Explanation
Participial phrases are dependent and modify a noun, here 'proposal.' The independent clause that can stand alone is 'The proposal was finally approved.'
Question 47Reading
An author presents a study finding that students who eat breakfast score higher on tests, then writes: 'This does not establish that breakfast causes higher scores.' Which reasoning concept does the author's caveat reflect?
- Anecdotal evidence always outweighs statistical evidence.
- Correlation does not by itself establish causation. Correct answer.
- Expert opinion is the only valid form of evidence.
- Sample size is irrelevant to a study's conclusions.
Explanation
Observing that two variables occur together does not prove that one causes the other, since other factors may be responsible. The author's caution correctly distinguishes correlation from causation.
Question 48Reading
A passage shifts from describing a drought's effects to quoting farmers, then to citing climate data. Which statement best evaluates how well the passage supports its central claim that the drought was unusually severe?
- The farmers' quotations alone are sufficient because they experienced the drought.
- The climate data are irrelevant because they do not describe individual experiences.
- The combination of personal accounts and climate data provides stronger support than either alone. Correct answer.
- The passage is unsupported because it mixes different kinds of evidence.
Explanation
Strong arguments often combine quantitative data with illustrative human accounts, which reinforce each other. Mixing evidence types strengthens rather than weakens support when each type is relevant.
Question 49Reading
In the sentence 'What the committee decided surprised everyone,' what is the grammatical function of 'What the committee decided'?
- It is a noun clause serving as the subject of 'surprised.' Correct answer.
- It is an independent clause joined to the main clause.
- It is an adjective clause modifying 'everyone.'
- It is an adverb clause modifying 'surprised.'
Explanation
A clause beginning with 'what' can function as a noun, and here it fills the subject slot before the verb 'surprised.' It is therefore a noun clause acting as subject.
Question 50Reading
A reader must decide whether an author's use of the word 'regime' rather than 'government' in a political passage carries a connotation. Which analysis is most defensible?
- 'Regime' often implies a government viewed as authoritarian or illegitimate, so the word choice may convey a negative stance. Correct answer.
- 'Regime' is purely technical and carries no evaluative shading.
- 'Regime' signals that the passage is about medicine rather than politics.
- 'Regime' and 'government' are perfectly interchangeable in all contexts.
Explanation
Word choice conveys connotation, and 'regime' frequently carries a negative or critical shading compared with the neutral 'government.' Skilled readers notice such loaded diction when judging an author's stance.
