Reading Comprehension
Reading Comprehension on the Pennsylvania State Trooper written exam asks you to extract meaning from short passages and answer questions about main idea, supporting detail, inference, vocabulary in context, and author's purpose. The passages are often practical or informational, so treat each one as a set of claims you can verify against the text.
Core rules
- Find the main idea first: ask what the whole passage is mostly about, not what one sentence says.
- Separate stated detail from inference. A valid inference must be supported by words in the passage, not by outside experience.
- For vocabulary, substitute each answer choice into the sentence and check the surrounding clause.
- Track scope words: all, some, only, except, primarily, best.
Worked example
Passage: 'The barracks replaced paper vehicle logs with an electronic system last spring. Supervisors can now review inspections the same day they are entered. The change followed a review that found several incomplete paper logs.' Question: What is the main idea? A) Paper logs are always incomplete. B) The barracks adopted an electronic logging system after finding problems with paper logs. C) Supervisors prefer electronic systems. D) Inspections are now done daily. Answer B. A overstates 'several'; C is not stated; D confuses same-day review with daily inspection. B captures the change and its cause.
Traps
- Choosing a true statement that is only a detail.
- Using real-world assumptions to answer an inference item.
- Confusing 'same day' with 'daily' or 'several' with 'all'.
- Ignoring the question stem's focus on the author's purpose rather than the topic.
