Grammar for HESI A2
1. Which word is used incorrectly in the following sentence? Jeremiah seemed enthusiastic when we reported on our astonishing success.
- A. seemed
- B. enthusiastic
- C. astonishing
- D. success
Correct answer: B
Rationale: The word 'enthusiastic' is used incorrectly in the sentence. It should be 'enthusiastic' instead of 'enthusiastically' since it is describing Jeremiah's state of being, not an action he performed. Adverbs like 'enthusiastically' are used to modify verbs, not adjectives like 'enthusiastic'. The other choices ('seemed,' 'astonishing,' 'success') are all used appropriately in the sentence and do not need any correction.
2. What type of transport moves substances across the cell membrane using energy?
- A. Passive Transport
- B. Active Transport
- C. Facilitated Diffusion
- D. Osmosis
Correct answer: B
Rationale: The correct answer is B: Active Transport. Active transport moves substances across the cell membrane by utilizing energy from the cell, typically in the form of ATP. This process allows the cell to move molecules against their concentration gradient, requiring energy expenditure. Choices A, C, and D are incorrect because passive transport does not require energy input, facilitated diffusion involves the assistance of proteins but does not directly use energy, and osmosis is the diffusion of water molecules specifically, not substances, across a selectively permeable membrane.
3. Select the correct word for the blank in the following sentence. Without ___________ , I never would have finished my degree.
- A. she
- B. he
- C. them
- D. hers
Correct answer: A
Rationale: In this sentence, 'she' is the correct word to use. The sentence implies that someone (a female) helped the speaker finish their degree. The pronoun 'she' is used to refer to a female person. Without this person's help, the speaker would not have completed their degree. Therefore, the correct word for the blank is 'she.' Choices B, C, and D are incorrect because they do not match the context of the sentence, which specifically mentions the need for help from a female individual.
4. What does bifurcate mean?
- A. Fold twice
- B. Flower biannually
- C. Divide in two forks
- D. Pierce two openings
Correct answer: C
Rationale: Bifurcate means to divide into two forks or branches. It comes from the Latin word "bi" meaning two and "furca" meaning fork. So, when something bifurcates, it splits into two separate paths or divisions. Choice A, "Fold twice," is incorrect as bifurcate doesn't involve folding. Choice B, "Flower biannually," is unrelated to the meaning of bifurcate. Choice D, "Pierce two openings," is also incorrect as it does not capture the true essence of bifurcate, which is about dividing into two forks or branches.
5. Which word is not spelled correctly in the context of the following sentence? 'The climate ___ is inappropriate for snow sports such as skiing.'
- A. climate
- B. hear
- C. inappropriate
- D. skiing
Correct answer: B
Rationale: The word 'hear' is misspelled; it should be 'here.' In the context of the sentence provided, 'hear' does not fit logically and should be replaced with 'here' to convey the intended meaning. 'Climate,' 'inappropriate,' and 'skiing' are all spelled correctly and are appropriate in the context of the sentence. 'Hear' is a homophone and does not make sense in this context.
