Question 1Reading

In a passage for the Iowa Assessments Reading test, a student reads: "The wind rattled the shutters all night, and by morning the porch was covered in leaves." Which statement best describes what the wind did in this sentence?

  1. It made the shutters shake with sound. Correct answer.
  2. It painted the porch a new color.
  3. It removed the shutters from the house.
  4. It stopped blowing before sunset.

Explanation

The verb "rattled" means to make a series of short knocking sounds or to shake noisily, so the wind caused the shutters to shake audibly. The other details in the sentence (leaves on the porch) support a night of strong wind, not removal of shutters or painting.

Question 2Reading

Read this sentence from a story: "Maya's backpack felt like a boulder as she trudged up the hill." What does the comparison mainly help the reader understand?

  1. Maya is climbing a rocky mountain trail.
  2. Maya has packed rocks in her bag.
  3. Maya is walking quickly to reach the top.
  4. Maya's backpack is heavy and hard to carry. Correct answer.

Explanation

A simile compares two things using "like" or "as"; here the backpack is compared to a boulder to suggest great weight. The word "trudged" reinforces slow, labored walking, so the comparison emphasizes heaviness rather than actual rocks.

Question 3Reading

A passage states: "The library will extend its weekend hours beginning next month." Which question is answered directly by this sentence?

  1. How many people visit the library on weekends?
  2. Who requested the longer hours?
  3. When will the new weekend hours start? Correct answer.
  4. Why did the library change its hours?

Explanation

The sentence gives a clear time frame, "beginning next month," so it directly answers when the new hours take effect. It does not give reasons, requesters, or attendance numbers.

Question 4Reading

Which sentence from a student report uses the word "effect" correctly?

  1. The new recess rule will effect how students line up.
  2. The effect of the new recess rule was shorter lines. Correct answer.
  3. Students effect that the rule is fair.
  4. The principal will effect a speech at the assembly.

Explanation

"Effect" as a noun means a result, so "the effect of the new rule was shorter lines" is correct. "Affect" is usually the verb meaning to influence, while "effect" as a verb means to bring about, which fits none of the other sentences.

Question 5Reading

Read the paragraph: "First, gather your materials. Next, cut the paper into strips. Then weave the strips together. Finally, trim the edges." How is this paragraph organized?

  1. By comparing two crafts
  2. By listing steps in order Correct answer.
  3. By explaining a problem and solution
  4. By describing causes and effects

Explanation

Signal words such as "first," "next," "then," and "finally" show a sequence of steps, which is chronological or sequential organization. The paragraph does not compare items, describe causes, or pose a problem.

Question 6Reading

In the sentence "The chef tasted the soup, and she smiled," what does the conjunction "and" do?

  1. It joins two related ideas of equal importance. Correct answer.
  2. It states a condition for the second action.
  3. It shows a contrast between two ideas.
  4. It introduces a cause for the first action.

Explanation

Coordinating conjunctions such as "and" join two independent clauses that are related and grammatically equal. "But" would signal contrast, "because" would signal cause, and "if" would signal condition.

Question 7Reading

A passage says: "The museum's newest exhibit features fossils found in Iowa." Which word from the sentence is a proper adjective?

  1. museum's
  2. fossils
  3. newest
  4. Iowa Correct answer.

Explanation

"Iowa" is a proper noun used here to describe the fossils, so it functions as a proper adjective and is capitalized. The other choices are a common adjective, a possessive noun, and a common noun.

Question 8Reading

Which sentence best states the main idea of a paragraph about how bees help farmers?

  1. Bees live in colonies with a single queen.
  2. Honey is a sweet food made by bees.
  3. Some people are allergic to bee stings.
  4. Bees pollinate crops, which helps farmers grow more food. Correct answer.

Explanation

A main idea must capture the whole paragraph's focus, which here is the connection between bees and farming. The other sentences are supporting details or unrelated facts about bees.

Question 9Reading

A student reads: "The old bridge groaned under the weight of the truck." Which type of figurative language is "groaned"?

  1. Simile
  2. Idiom
  3. Hyperbole
  4. Personification Correct answer.

Explanation

Personification gives human qualities to nonhuman things; a bridge cannot actually groan, so the word attributes a human sound to it. A simile uses "like" or "as," hyperbole exaggerates, and an idiom is a fixed expression.

Question 10Reading

Read this sentence: "Although the trail was steep, the hikers reached the summit before noon." What relationship does "although" show between the two parts?

  1. A contrast between difficulty and success Correct answer.
  2. A cause and its result
  3. A sequence of two steps
  4. A similarity between two events

Explanation

"Although" is a subordinating conjunction that signals concession or contrast, setting the steep trail against the hikers' success. It does not indicate similarity, order, or cause and effect.

Question 11Reading

A passage about recycling says: "Recycling one ton of paper saves about seventeen trees." How does this detail most likely function in the passage?

  1. It introduces a new topic unrelated to recycling.
  2. It provides evidence that recycling has environmental benefits. Correct answer.
  3. It explains how trees are planted.
  4. It states the author's opinion about paper.

Explanation

A specific statistic linking recycling to saved trees serves as supporting evidence for a claim about environmental benefits. It is factual support, not a new topic, a planting explanation, or an opinion.

Question 12Reading

Which sentence uses commas correctly in a series?

  1. She packed a map a compass, and a water bottle.
  2. She packed, a map, a compass and a water bottle.
  3. She packed a map, a compass, and a water bottle. Correct answer.
  4. She packed a map, a compass and, a water bottle.

Explanation

Items in a series are separated by commas between each item, so the correct sentence places a comma after "map" and after "compass." Commas should not separate the verb from its object or fall after a conjunction.

Question 13Reading

Read the sentence: "The scientist who discovered the vaccine received an award." Which part is the relative clause?

  1. who discovered the vaccine Correct answer.
  2. The scientist
  3. The scientist who discovered the vaccine
  4. received an award

Explanation

A relative clause begins with a relative pronoun such as "who" and modifies a noun; here "who discovered the vaccine" describes the scientist. The other choices are the subject, the main verb phrase, or the entire subject phrase.

Question 14Reading

A student needs to find the meaning of the word "arid" while reading a passage about deserts. Which reference would be most efficient?

  1. An atlas map of deserts
  2. A dictionary entry for "arid" Correct answer.
  3. A style guide for citations
  4. A thesaurus entry for "dry"

Explanation

A dictionary gives a word's meaning directly, which is what the student needs. A thesaurus supplies synonyms but not definitions, and an atlas or style guide does not define words.

Question 15Reading

Read the passage: "Many towns now plant trees along busy streets. The trees provide shade on hot days and absorb noise from traffic. They also make streets more attractive to shoppers." What is the author's main purpose?

  1. To explain the benefits of planting street trees Correct answer.
  2. To compare towns with and without shoppers
  3. To describe how to plant a tree correctly
  4. To persuade readers to avoid busy streets

Explanation

The passage lists several advantages of street trees, so the purpose is to explain benefits. It does not urge readers to avoid streets, give planting instructions, or compare towns.

Question 16Reading

Which sentence correctly uses an apostrophe to show possession?

  1. The student's projects were displayed in the halls'.
  2. The students' projects were displayed in the hall. Correct answer.
  3. The students projects' were displayed in the hall.
  4. The students's projects were displayed in the hall.

Explanation

For a plural noun ending in s, possession is shown by adding only an apostrophe after the s, giving "students'." The other sentences misplace the apostrophe or add an unnecessary s.

Question 17Reading

A passage includes the sentence: "The mayor argued that the new park would cost too much." What does the word "argued" suggest about the mayor's statement?

  1. The mayor asked a question about the park.
  2. The mayor shouted angrily at the audience.
  3. The mayor proved the park was impossible.
  4. The mayor presented a position that others might dispute. Correct answer.

Explanation

In this context "argued" means presented a reasoned position, which implies that others may disagree. It does not mean proved, shouted, or asked.

Question 18Reading

Which sentence correctly uses "their," "there," or "they're"?

  1. The players left they're equipment on the bus.
  2. The books are over there on the shelf. Correct answer.
  3. There team won the championship game.
  4. Their going to practice after school.

Explanation

"There" indicates a place, so "over there on the shelf" is correct. "Their" is possessive, and "they're" is a contraction of "they are."

Question 19Reading

A student reads two articles about school start times. One says later start times improve student sleep; the other says they make after-school activities harder to schedule. What is the best way to describe the relationship between the articles?

  1. They present identical arguments.
  2. They present opposing viewpoints on the same issue. Correct answer.
  3. They describe unrelated topics.
  4. They both support later start times without any concerns.

Explanation

One article emphasizes benefits and the other emphasizes drawbacks of the same change, so they offer opposing viewpoints on one issue. They are related, not identical, and the second article raises a concern.

Question 20Reading

Read this sentence: "Running down the street, the dog chased the ball." Which phrase is a participial phrase?

  1. down the street
  2. the dog chased the ball
  3. Running down the street Correct answer.
  4. the ball

Explanation

A participial phrase begins with a participle, a verb form ending in -ing or -ed used as an adjective; "Running down the street" modifies "the dog." The other choices are a clause, a noun, or a prepositional phrase.

Question 21Reading

An author writes: "We must act now to protect our rivers before it is too late." Which word best describes the tone of this sentence?

  1. Playful
  2. Humorous
  3. Indifferent
  4. Urgent Correct answer.

Explanation

The phrases "must act now" and "before it is too late" create a sense of urgency. The sentence shows concern, not humor, indifference, or playfulness.

Question 22Reading

A passage states: "The company's profits rose after it began offering free shipping." Which conclusion is best supported by this statement?

  1. Free shipping caused all customers to buy more products.
  2. Customers disliked the free shipping policy.
  3. Offering free shipping may have contributed to higher profits. Correct answer.
  4. The company will always offer free shipping.

Explanation

The statement links free shipping and rising profits, so a cautious conclusion is that free shipping may have helped. It does not prove that all customers bought more, that the policy is permanent, or that customers disliked it.

Question 23Reading

Read the paragraph: "Some say homework builds responsibility. Others argue it leaves too little time for family and rest. Both sides agree that how much homework is assigned matters." What does the last sentence do?

  1. It introduces a new argument against homework.
  2. It identifies a point of agreement between the two sides. Correct answer.
  3. It repeats the first sentence exactly.
  4. It proves that homework is harmful.

Explanation

The phrase "both sides agree" signals common ground, so the sentence identifies a shared point. It does not add a new argument, prove harm, or simply repeat the opening.

Question 24Reading

A reader wants to evaluate whether an online article about nutrition is reliable. Which action would best help?

  1. Counting the number of paragraphs in the article
  2. Identifying the author's credentials and sources Correct answer.
  3. Reading only the first sentence of the article
  4. Checking whether the article has many colorful images

Explanation

Reliability depends on the author's expertise and the quality of the sources cited, so checking credentials and sources is the strongest step. Images, paragraph counts, and partial reading do not establish accuracy.

Question 25Reading

Read the sentence: "The proposal, which the committee reviewed for weeks, was finally approved." Which statement about the sentence is accurate?

  1. The sentence contains no subordinate clause.
  2. The clause "which the committee reviewed for weeks" adds nonessential information and is set off by commas. Correct answer.
  3. The word "finally" is a conjunction joining two clauses.
  4. The clause "which the committee reviewed for weeks" is essential to identify the proposal.

Explanation

A nonrestrictive relative clause adds extra information about an already identified noun and is set off by commas, as here. Because it is set off, it is not essential to identify the proposal.

Question 26Reading

Read this sentence: "After the final bell rang, students poured out of the building like water from a broken dam." What does the simile "like water from a broken dam" help the reader understand about the students?

  1. They were unsure where to go.
  2. They moved in a sudden, forceful rush. Correct answer.
  3. They were quiet and orderly.
  4. They were worried about the noise.

Explanation

A simile compares two things using "like" or "as." Water bursting from a broken dam moves fast and with great force, so the comparison emphasizes how quickly and forcefully the students left the building. The other choices describe quiet, confusion, or worry, which the image of rushing water does not support.

Question 27Reading

A student is reading a science article and comes to the word "nocturnal" in the sentence "Owls are nocturnal, hunting mostly after dark." Which strategy best helps the student figure out the meaning of "nocturnal" from the sentence?

  1. Counting the syllables in "nocturnal"
  2. Sounding out the word letter by letter
  3. Looking for a synonym for "owls"
  4. Using the context clue "hunting mostly after dark" Correct answer.

Explanation

Context clues are words or phrases near an unfamiliar word that help reveal its meaning. The phrase "hunting mostly after dark" directly explains when owls are active, so it is the best clue to the meaning of "nocturnal" (active at night). The other strategies do not use the surrounding text to build meaning.

Question 28Reading

Read this sentence from a story: "Maria stared at the closed door, her hand hovering over the knob." What does the detail about Maria's hand most likely suggest about her?

  1. She is angry at the person inside.
  2. She feels uncertain about going in. Correct answer.
  3. She has forgotten how to open doors.
  4. She is in a hurry to enter.

Explanation

A hand hovering over a knob without turning it suggests hesitation. The author uses this physical detail to show Maria's inner uncertainty rather than stating it directly. The other choices add emotions or actions that the text does not support.

Question 29Reading

Which sentence from a report about Iowa weather uses the semicolon correctly?

  1. The storm knocked out power; because the school canceled classes.
  2. The storm knocked out power; the school canceled classes. Correct answer.
  3. The storm knocked out power; and the school canceled classes.
  4. The storm knocked out power; which the school canceled classes.

Explanation

A semicolon can join two independent clauses that are closely related. "The storm knocked out power" and "the school canceled classes" are both complete sentences, so a semicolon correctly separates them. The other options add a conjunction or relative word after the semicolon, which is incorrect punctuation for joining clauses.

Question 30Reading

Read this paragraph: "The city council voted to add bike lanes on Main Street. Supporters say the lanes will make cycling safer and reduce traffic. Opponents worry that removing parking spaces will hurt nearby businesses." Which sentence best summarizes the paragraph?

  1. Supporters of bike lanes believe cycling is safer than driving.
  2. The city council voted to remove all parking spaces on Main Street.
  3. Opponents of bike lanes want to build new parking garages.
  4. The city council approved bike lanes, which supporters believe will improve safety and traffic but opponents fear will harm businesses. Correct answer.

Explanation

A summary should capture the main idea and key points without adding new information. The paragraph presents a decision and two opposing views, and option A restates both sides accurately. The other choices focus on one detail or introduce ideas not in the text.

Question 31Reading

Read this sentence: "The teacher, who had graded papers all weekend, handed back the essays on Monday." Which statement correctly identifies the function of the clause "who had graded papers all weekend"?

  1. It is a phrase that lacks a subject and verb.
  2. It is an independent clause that could stand alone as a sentence.
  3. It is an adverb clause that tells when the teacher handed back essays.
  4. It is a nonessential relative clause that adds information about the teacher. Correct answer.

Explanation

The clause begins with the relative pronoun "who" and modifies "teacher." It is set off by commas because it provides extra, nonessential information; the sentence would still make sense without it. It is not independent, adverbial, or a phrase.

Question 32Reading

A passage states: "The new library opened last month. Since then, visits by teenagers have doubled, and the number of books checked out by young readers has risen sharply." Which conclusion is best supported by the passage?

  1. The old library was too small for the town's population.
  2. The new library has encouraged more reading among teenagers. Correct answer.
  3. Teenagers prefer the new library because it has more computers.
  4. Teenagers are reading fewer books than before.

Explanation

The passage gives evidence that teen visits and teen book checkouts increased after the new library opened. The safest conclusion is that the library has encouraged more reading among teenagers. The other choices either contradict the data or add details not stated.

Question 33Reading

Read this sentence: "The hikers packed water, granola bars, and a map, but they forgot to bring a compass." Which revision corrects the punctuation error?

  1. The hikers packed water, granola bars and a map, but they forgot to bring a compass.
  2. The hikers packed water granola bars and a map, but they forgot to bring a compass.
  3. The hikers packed water, granola bars, and a map, but they forgot, to bring a compass.
  4. The hikers packed water, granola bars, and a map but forgot to bring a compass. Correct answer.

Explanation

When two independent clauses are joined by a coordinating conjunction like "but," a comma is needed before the conjunction. Here, the first clause shares the subject "hikers" with the second, so the sentence can be written as one clause with a compound verb, removing the need for a comma before "but." Option A does this correctly.

Question 34Reading

Read this sentence: "The scientist's discovery, which was published in a major journal, changed the way doctors treat the disease." Which part of the sentence is the main clause?

  1. which was published in a major journal
  2. the way doctors treat the disease
  3. The scientist's discovery, which was published
  4. The scientist's discovery changed the way doctors treat the disease. Correct answer.

Explanation

The main clause contains the subject and main verb and can stand alone as a complete sentence. Removing the relative clause "which was published in a major journal" leaves "The scientist's discovery changed the way doctors treat the disease," which is the main clause. The other choices are phrases or dependent clauses.

Question 35Reading

A student is writing a report and wants to use a word that means "very careful about details." Which word best fits?

  1. Hesitant
  2. Impulsive
  3. Indifferent
  4. Meticulous Correct answer.

Explanation

"Meticulous" describes someone who shows great attention to detail. The other words describe a lack of interest, acting without thought, or uncertainty, none of which match the intended meaning. Choosing the precise word helps the report convey the right shade of meaning.

Question 36Reading

Read this paragraph: "Many students bring water bottles to school. Some schools have installed refill stations to make filling them easier. These stations reduce plastic waste and encourage students to drink more water." What is the main idea of the paragraph?

  1. Refill stations at schools help students and the environment. Correct answer.
  2. Water fountains in schools are often broken.
  3. Students should bring reusable water bottles to school.
  4. Plastic waste is the biggest problem facing schools today.

Explanation

The paragraph explains that refill stations make filling bottles easier, reduce plastic waste, and encourage water consumption. The main idea combines these benefits. The other choices focus on a single detail or introduce ideas not stated.

Question 37Reading

Read this sentence from an editorial: "It is time for our town to stop ignoring the crumbling sidewalks that endanger pedestrians every day." Which word best describes the tone of the sentence?

  1. Urgent Correct answer.
  2. Humorous
  3. Uncertain
  4. Nostalgic

Explanation

The words "time to stop ignoring" and "endanger" create a sense of urgency and concern. The author is calling for immediate action, not joking, reminiscing, or expressing doubt. Tone is conveyed through word choice and the attitude toward the subject.

Question 38Reading

A passage includes the sentence: "The company's new policy, while popular with employees, has been criticized by some customers." Which statement best explains the function of the word "while" in the sentence?

  1. It introduces a cause-and-effect relationship.
  2. It indicates the time when the policy was created.
  3. It introduces a contrast between two groups' reactions. Correct answer.
  4. It shows that the policy is popular with everyone.

Explanation

"While" can signal contrast, similar to "although." Here it sets the employees' positive reaction against the customers' criticism. It does not refer to time, show universal popularity, or establish cause and effect.

Question 39Reading

Read this sentence: "The author's use of the phrase 'a river of traffic' in paragraph 3 is an example of which literary device?"

  1. Simile
  2. Onomatopoeia
  3. Metaphor Correct answer.
  4. Personification

Explanation

A metaphor directly compares two unlike things without using "like" or "as." Calling traffic "a river" suggests that the cars flow continuously. A simile would use "like" or "as," personification would give human traits to nonhuman things, and onomatopoeia would use words that imitate sounds.

Question 40Reading

A student is comparing two articles about year-round school. Article A cites a study showing that students forget less over long breaks. Article B quotes parents who say summer break is important for family time. Which statement best evaluates how the two articles support their claims?

  1. Both articles rely mainly on emotional appeals.
  2. Article B provides stronger scientific evidence than Article A.
  3. Both articles use the same type of evidence.
  4. Article A uses research evidence, while Article B uses personal opinion. Correct answer.

Explanation

Article A supports its claim with a study, which is a form of research evidence. Article B relies on parents' opinions about family time, which is a personal perspective. Recognizing the type of evidence helps a reader judge how well each claim is supported.

Question 41Language

Read this sentence: 'The committee reviewed the proposal carefully before it voted.' Which word in the sentence is the simple subject?

  1. proposal
  2. committee Correct answer.
  3. carefully
  4. voted

Explanation

The simple subject is the noun or pronoun that performs the action of the main verb. Here 'committee' performs the action 'reviewed', while 'proposal' is the object of the verb and 'carefully' is an adverb modifying it.

Question 42Language

In the sentence 'Marta, who has coached for ten years, leads the debate team,' what grammatical role does the clause 'who has coached for ten years' play?

  1. It is an adverb clause modifying leads.
  2. It is an adjective clause modifying Marta. Correct answer.
  3. It is an independent clause joined by a comma.
  4. It is a noun clause acting as the subject.

Explanation

A relative clause beginning with 'who' modifies the noun immediately before it, which is 'Marta'. Because it describes a person's identity rather than telling when or why the action happens, it functions as an adjective clause.

Question 43Language

Which sentence uses an apostrophe correctly for a Language assessment item about possession and contraction?

  1. The teachers lounge was closed for repair's.
  2. The student's were excited about the science fair.
  3. Its going to rain during the field trip today.
  4. The students' projects were displayed in the gymnasium. Correct answer.

Explanation

A plural noun ending in -s forms the possessive by adding only an apostrophe after the s, so 'students'' correctly shows that the projects belong to multiple students. The other options misuse apostrophes with plurals, contractions, or possessive pronouns.

Question 44Language

A Language item asks you to identify the best meaning of the prefix in the word 'bicycle.' What does the prefix 'bi-' mean?

  1. against
  2. around
  3. two Correct answer.
  4. before

Explanation

The prefix 'bi-' comes from Latin and means 'two,' as in 'bicycle' (two wheels) and 'bilingual' (two languages). Recognizing common prefixes helps a reader infer the meaning of unfamiliar words.

Question 45Language

Read this sentence: 'The quarterback threw a perfect spiral.' Which type of figurative or descriptive language does 'perfect spiral' represent?

  1. precise descriptive adjective and noun Correct answer.
  2. hyperbole
  3. personification
  4. a simile

Explanation

'Perfect spiral' uses an adjective and noun to describe the flight of the ball directly, without comparison. A simile would use 'like' or 'as,' personification would give human traits to an object, and hyperbole would exaggerate.

Question 46Language

Which sentence correctly uses a semicolon in a Language assessment context?

  1. The rain stopped; the game resumed. Correct answer.
  2. The rain stopped; because the game resumed.
  3. The rain stopped; and the game resumed.
  4. The rain stopped; resuming the game.

Explanation

A semicolon joins two closely related independent clauses without a coordinating conjunction. 'The rain stopped' and 'the game resumed' are each complete sentences, so the semicolon is appropriate.

Question 47Language

In the sentence 'The scientist examined the samples thoroughly,' which word is the adverb?

  1. samples
  2. examined
  3. thoroughly Correct answer.
  4. scientist

Explanation

An adverb modifies a verb, adjective, or another adverb, often answering how, when, or where. 'Thoroughly' tells how the scientist examined the samples, so it is the adverb.

Question 48Language

Which sentence uses 'their,' 'there,' and 'they're' correctly?

  1. They're going to bring there books over their.
  2. There going to bring they're books over their.
  3. They're going to bring their books over there. Correct answer.
  4. Their going to bring there books over they're.

Explanation

'They're' is the contraction for 'they are,' 'their' is the possessive form, and 'there' indicates a place. Only the first option assigns each homophone to its correct meaning.

Question 49Language

Which sentence contains a compound subject?

  1. Ravi and his sister entered the essay contest. Correct answer.
  2. Ravi, a strong writer, entered the contest.
  3. Ravi entered the essay contest quickly.
  4. Ravi entered and won the essay contest.

Explanation

A compound subject contains two or more subjects joined by a conjunction and sharing the same verb. In 'Ravi and his sister entered,' both nouns perform the action 'entered.'

Question 50Language

Read this sentence: 'Having finished the experiment, the results were recorded by the team.' What is the problem with this sentence?

  1. It contains a run-on sentence.
  2. It contains faulty parallelism.
  3. It contains a comma splice.
  4. It contains a dangling modifier. Correct answer.

Explanation

The introductory participial phrase 'Having finished the experiment' should modify the subject of the main clause. The stated subject is 'the results,' which cannot finish an experiment, so the modifier dangles.
