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.

Correct Answer: A

Rationale: The correct phrase to use in this context is 'that has,' indicating possession or similarity between words. Synonyms are words that have meanings similar to those of other words, making choice A the most appropriate selection. Choices B, C, and D are incorrect as they do not correctly convey the relationship of possessing similar meanings between words.

Correct Answer: B

Rationale: The correct answer is 'B: The team of players is winning.' The error in this sentence is a subject-verb agreement issue. 'Team' is a singular noun, so it should take a singular verb 'is' instead of 'are.' The subject-verb agreement rule states that singular subjects should be paired with singular verbs, while plural subjects should be paired with plural verbs. Choices A, C, and D all demonstrate correct subject-verb agreement as they correctly match singular subjects ('group,' 'list,' 'pile') with singular verbs ('is,' 'is,' 'is').

Correct Answer: B

Rationale: The correct answer is B: 'Purified.' Aseptic means free from contamination or purified. In medical and scientific contexts, aseptic techniques are used to prevent contamination and maintain sterility in environments or procedures. Choice A, 'Infected,' is incorrect as aseptic refers to being free from contamination, not being infected. Choice C, 'Contaminated,' is incorrect as aseptic means the opposite of contaminated. Choice D, 'Sterilized,' is incorrect as aseptic focuses on the absence of contamination rather than the process of sterilization.

Correct Answer: A

Rationale: Sallow skin is a term used to describe skin that appears yellowish in color. This discoloration can be due to various factors, such as an underlying health condition, poor circulation, or certain medications. Observing sallow skin can be an important clinical indicator that prompts further investigation into the patient's overall health status. Choice B, blue tint, is incorrect as sallow skin is not associated with a blue color. Choice C, red tint, and Choice D, green tint, are also incorrect as sallow skin specifically refers to a yellowish complexion, not red or green.
