HESI A2 Reading Comprehension

1. What is the meaning of the word 'shifts' as used in the third paragraph?

A. Alterations
B. Stints
C. Removals
D. Transfers

Correct answer: A

Rationale: In this context, 'shifts' refers to changes or alterations in brain chemistry and electrophysiology. The word 'alterations' best captures the idea that significant changes are occurring in the brain. 'Stints' (choice B) refer to short periods of time or work, which is not the meaning intended here. 'Removals' (choice C) and 'transfers' (choice D) do not fit the context of the sentence and are not related to the changes happening in the brain as described in the extract.

2. The passage explicitly states?

A. That the highest card within the 'trump' suit always wins the trick.
B. That there is a pile of leftover cards that is placed in the middle of the game table.
C. If a player cannot follow suit, they lose their turn to the next player.
D. The Ace card is always the lowest card.

Correct answer: A

Rationale: The correct answer is A: 'That the highest card within the 'trump' suit always wins the trick.' The passage explicitly mentions that in the game of Bridge, if a player plays a card from the trump suit, it always wins the trick. This detail is clearly stated in the text, making it the correct choice. Choice B is incorrect as there is no mention of a pile of leftover cards in the passage. Choice C is incorrect as the passage does not state that a player loses their turn if they cannot follow suit; instead, they play any card. Choice D is incorrect as the passage states that the ace is high, not low.

Rationale: Based on the provided extract, sleeping helps with fatigue, memory, and learning. The passage mentions how a nap can refresh the brain, improve the ability to learn and remember, and enhance memory.

A. Siam was renamed Thailand in the past
B. The author dislikes parlor games
C. Elephants are difficult to take care of and train
D. White elephants were considered sacred and a burden to their recipients

Correct answer: A

Rationale: The correct answer is A. The article explicitly states that centuries ago, Siam, now known as Thailand, had the custom of giving white elephants as punishment. This implies that Siam was renamed Thailand in the past. The other choices (B, C, D) are not supported by the content of the article. Choice B is incorrect as the author does not express any dislike for parlor games. Choice C is incorrect as the article does not mention that elephants are easy or difficult to take care of and train. Choice D is incorrect as the article describes white elephants as sacred and a burden to their recipients, not as hard workers in the cane fields.
