What is the main idea of the paragraph?
- A. Coal mining is a dangerous job.
- B. Coal mining is a dirty job.
- C. Coal mining takes place underground.
- D. Coal miners risk injury on a daily basis.
Correct Answer: A
Rationale: The main idea of the paragraph is to highlight the dangers associated with coal mining. The sentence 'Coal miners risk injury and health issues on a daily basis' supports the concept that coal mining is a dangerous job. Choice B is incorrect as it focuses on cleanliness rather than safety. Choice C is incorrect as the location of coal mining is not the primary focus of the paragraph. Choice D is incorrect as it does not encompass the full extent of risks mentioned in the paragraph.

Select the meaning of the highlighted word in the sentence based on the context clues: If you wake up outside in your pajamas in the middle of the night, you may be a 'somnambulist'.
- A. Explorer
- B. Magician
- C. Insomniac
- D. Sleepwalker
Correct Answer: D
Rationale: The correct answer is D: 'Sleepwalker'. The word 'somnambulist' refers to a sleepwalker, as indicated by the context of waking up outside in pajamas in the middle of the night. A sleepwalker is someone who walks while asleep, and this matches the situation described in the sentence. Choices A, B, and C are incorrect because they do not align with the behavior of walking during sleep, which is characteristic of a somnambulist/sleepwalker.
Identify the sentence that contains a dependent clause.
- A. The cat sat on the mat.
- B. The cat sat on the mat after it ate.
- C. The cat will sit on the mat tomorrow.
- D. The cat is sitting on the mat.
Correct Answer: B
Rationale: The correct answer is B: 'The cat sat on the mat after it ate.' 'After it ate' is a dependent clause because it cannot stand alone as a sentence. It is dependent on the main clause 'The cat sat on the mat.' Choice A is a simple sentence without a dependent clause. Choice C is a sentence with a time adverbial modifying 'The cat will sit on the mat,' not a dependent clause. Choice D is a sentence in the present continuous tense, also lacking a dependent clause.
Which of the following is the most reliable source for scholarly research?
- A. Peer-reviewed articles
- B. Wikipedia
- C. Opinion articles from a newspaper
- D. Blogs and other social media
Correct Answer: A
Rationale: The correct answer is 'Peer-reviewed articles.' Peer-reviewed articles are considered highly reliable because they undergo a rigorous evaluation process by experts in the field before publication. This process ensures that the research presented is of high quality and meets academic standards. Choice B, 'Wikipedia,' is not considered a reliable source for scholarly research as it can be edited by anyone, leading to potential inaccuracies. Choice C, 'Opinion articles from a newspaper,' may provide perspectives but may not always be based on rigorous research or evidence. Choice D, 'Blogs and other social media,' lack the rigorous review process that peer-reviewed articles undergo, making them less reliable for scholarly research.
Which of the following suffixes denotes a state or quality?
- A. -ic
- B. -ness
- C. -ous
- D. -ful
Correct Answer: B
Rationale: The suffix "-ness" indicates a state or quality, as seen in words like "happiness" (the state of being happy). Choice A, "-ic," typically denotes characteristics or qualities, such as in "heroic." Choice C, "-ous," often signifies the presence of a quality or relationship, like in "poisonous." Choice D, "-ful," usually means full of or characterized by, as in "beautiful." Therefore, the correct answer is B because it best fits the description of indicating a state or quality.
The old clock hadn't worked in years, and _____ Ally finally decided to take it off the wall. Which of the following transition words or phrases is most appropriate to complete the sentence?
- A. as a result
- B. conversely
- C. then again
- D. similarly
Correct Answer: A
Rationale: The correct answer is 'as a result.' This transition word is most suitable in this context as it indicates a logical consequence. The old clock not working for years led to Ally deciding to take it off the wall. Choices B, C, and D are incorrect. 'Conversely' suggests a contrast, 'then again' implies reconsideration or a contrasting point, and 'similarly' indicates a comparison, none of which align with the cause-and-effect relationship presented in the sentence.
