Rationale: The correct answer is B: Drooping or loose. Flaccid means lacking firmness or stiffness, often used to describe something that is limp or lacking in strength or vigor. In this context, flaccid refers to something that is drooping or loose. Choice A is incorrect as light-colored does not relate to the definition of flaccid. Choice C is incorrect as uncontaminated is not a synonym of flaccid. Choice D is incorrect as unusually aggressive is unrelated to the meaning of flaccid.

Rationale: The correct answer is B: Separated. In this context, 'winnowed' means to separate the applicants from the group based on their qualifications or suitability. The process involves carefully selecting or eliminating individuals. The other choices are incorrect because: A: Escorted - This implies guiding or accompanying someone, which is not the action described in the sentence. C: Elevated - This suggests raising someone to a higher position, which does not fit the context of eliminating applicants. D: Summoned - This means calling someone to a place, which is not what is happening in the sentence where applicants are being removed from the group.

Rationale: The correct answer is A: A test of brain activity. EEG stands for Electroencephalogram, which is a test that measures electrical activity in the brain. This test is commonly used to diagnose epilepsy, sleep disorders, and other neurological conditions. Choice B is incorrect as EEG is not a service but a diagnostic test. Choice C is incorrect as EEG does not monitor heartbeats. Choice D is incorrect as EEG has no relation to dentistry. EEG specifically focuses on brain activity, making choice A the most appropriate description.

Correct Answer: C

Rationale: The correct answer is C: nostrum. A remedy is a substance or treatment that cures ailments. "Nostrum" is a synonym for remedy or cure, making it the most appropriate choice. A: inoculation refers to the process of introducing a vaccine to prevent disease. B: indicator is something that provides information or points out a condition, not necessarily a cure. D: serum is a component of blood and not specifically related to curing ailments. Therefore, C is the correct answer because it directly relates to the concept of a remedy curing ailments.

Correct Answer: C

Rationale: The correct answer is C: Merge. In the given sentence, 'amalgamate' is used in the context of two or more companies coming together to form a single entity.

B: Move - This refers to changing physical location and is unrelated to the context of companies merging. D: Regroup - This means to reassemble or reorganize, which is different from merging into a single entity.
