1. Choose the meaning of the word 'intramuscularly' in the following sentence: 'This vaccine must only be used intramuscularly and as a single-dose vial.'

• A. Between muscles
• B. Into muscles
• C. Without muscles
• D. On top of muscles

Correct answer: B

Rationale: The word 'intramuscularly' in the sentence indicates that the vaccine should be used by injection directly into the muscles. This means the correct meaning is 'into muscles,' making option B the most suitable choice. Choices A, C, and D are incorrect because 'intramuscularly' specifically refers to administering something inside the muscle, not between muscles, without muscles, or on top of muscles.

2. What type of reaction involves atoms attempting to achieve stable electron configurations?

• A. Chemical
• B. Nuclear
• C. Physical
• D. Mechanical

Correct answer: A

Rationale: In a chemical reaction, atoms interact to achieve stable electron configurations through the formation of new chemical bonds or the breaking of existing ones. This process aims to reach a more stable state by filling or emptying electron orbitals, leading to the formation of new substances with more stable configurations. Choice B, nuclear reactions, involve changes in the atomic nucleus rather than electron configurations. Choice C, physical reactions, involve changes in physical state or appearance without changing the chemical makeup. Choice D, mechanical reactions, do not involve the rearrangement of electrons to achieve stable configurations.

3. Which of the following is a tertiary consumer?

• A. Owl
• B. Shrew
• C. Grasshopper
• D. Wheat

Correct answer: A

Rationale: The correct answer is A, Owl. Tertiary consumers are organisms that feed on secondary consumers, which, in turn, feed on primary consumers. Owls are considered tertiary consumers because they primarily feed on animals such as rodents, which are secondary consumers. Shrew (choice B) is a secondary consumer, feeding on insects and worms, placing it at a lower trophic level than the owl. Grasshopper (choice C) is a primary consumer, feeding on plants. Wheat (choice D) is not a consumer in the food chain but a plant.

4. What is the meaning of exacerbate?

• A. To lessen in intensity
• B. To make worse
• C. To neutralize
• D. To control

Correct answer: B

Rationale: The correct answer is B: 'To make worse.' Exacerbate means to worsen or make a situation, condition, or problem more severe or intense, not to lessen it. Therefore, if something exacerbates a situation, it means it makes it worse. Choices A, C, and D are incorrect because exacerbate does not mean to lessen in intensity, neutralize, or control the situation, but rather to worsen it.

5. Which phrase should be moved to the end of the sentence? 'The painter decided to use the urn as his subject with flowers on the table.'

• A. as his subject
• B. with flowers on the table
• C. use the urn as his subject
• D. with the urn

Correct answer: B

Rationale: Moving 'with flowers on the table' to the end of the sentence improves the sentence flow and clarity. This placement helps to maintain a logical sequence of events, enhancing the reader's understanding. Choice A, 'as his subject,' is an integral part of the main action and should not be moved. Choice C, 'use the urn as his subject,' disrupts the verb-object relationship and makes the sentence less coherent. Choice D, 'with the urn,' lacks context and does not provide a smooth transition when placed at the end of the sentence.
