1. Choose the meaning of the word inhibiting in the following sentence: 'This medication works by inhibiting the action of a certain enzyme.'

A. Occupying
B. Speeding
C. Hindering
D. Enhancing

Correct answer: C

Rationale: Inhibiting means to prevent, restrain, or impede. In the context of the sentence, inhibiting the action of a certain enzyme refers to hindering or slowing down the enzyme's activity. Choice A ('Occupying') is incorrect as inhibiting does not mean taking up space. Choice B ('Speeding') is incorrect as inhibiting does not mean to accelerate. Choice D ('Enhancing') is incorrect as inhibiting is the opposite of enhancing.

2. Choose the meaning of the word 'disregard' in the following sentence: 'He chose to disregard the warnings.'

A. Have no opinion about
B. Pay attention to
C. Care for
D. Ignore

Correct answer: D

Rationale: The correct meaning of 'disregard' in the sentence provided is 'to ignore.' When someone disregards something, they are choosing not to pay attention to it or consider it important. Choice A, 'Have no opinion about,' is incorrect as disregard implies actively ignoring something rather than having no opinion. Choice B, 'Pay attention to,' is the opposite of disregard. Choice C, 'Care for,' is also the opposite of disregard, as caring for something implies giving it importance and attention.

3. What is the CORRECT CONTRACTION for 'will not'?

A. Won't
B. Willn't
C. Wouldn't
D. Will'nt

Correct answer: A

Rationale: The correct contraction for 'will not' is 'won't'. 'Willn't' (Choice B) is not a standard contraction in English. 'Wouldn't' (Choice C) is the contraction for 'would not,' not 'will not.' 'Will'nt' (Choice D) is not a recognized contraction in English. Therefore, 'won't' is the correct choice as the contraction for 'will not.'

4. The student observed the tricky procedure with a certain amount of trepidation. What does trepidation mean?

A. Confidence
B. Misgivings
C. Fear
D. Doubt

Correct answer: B

Rationale: The correct answer is B: Misgivings. Trepidation means a feeling of fear or apprehension. In this context, the student observed the procedure with a certain amount of trepidation, indicating that they were feeling uneasy or fearful. Choices A, C, and D are incorrect. Confidence (choice A) is the opposite of trepidation, as it denotes a feeling of self-assurance. Fear (choice C) is the closest synonym to trepidation, making it an attractive distractor, but it is not the correct answer. Doubt (choice D) is different from trepidation, as doubt refers to a feeling of uncertainty or lack of conviction, not necessarily fear or apprehension.

5. What is the process of digestion?

A. Production of enzymes
B. The mechanical and chemical breakdown of food
C. Absorption of nutrients in the blood
D. Movement of enzymes

Correct answer: B

Rationale: The correct answer is B: The mechanical and chemical breakdown of food. Digestion involves breaking down food mechanically and chemically into smaller components for absorption by the body. This process occurs in the digestive system, preparing nutrients for absorption in the intestines. Choices A, C, and D are incorrect because digestion is not solely about the production of enzymes, absorption of nutrients in the blood, or movement of enzymes; it primarily involves breaking down food for nutrient absorption.
