Correct Answer: C

Rationale: The correct answer is 'C: Immigrant.' An immigrant is a person who comes to live permanently in a foreign country, such as the United States. Choice A, 'Immigrate,' refers to the action of entering a foreign country to live there. Choice B, 'Migrate,' means to move from one place to another. Choice D, 'Emigrant,' is someone who leaves their own country to settle permanently in another.

Correct Answer: A

Rationale: The correct answer is A: 'Confinement away from the general population.' Quarantine refers to keeping someone isolated from the general population to prevent the spread of disease. Choice B, 'A specialist's care,' is incorrect as it refers to medical treatment by a specialist, not isolation. Choice C, 'Experimental drug therapy,' is incorrect as it involves the administration of new drugs for research purposes, not isolation. Choice D, 'Imprisonment in a rehabilitation unit,' is incorrect as it implies being detained in a rehabilitation facility, not isolation for health reasons.

Correct Answer: A

Rationale: The correct answer is A: 'Undesirable.' In this context, 'adverse' means harmful or undesirable, specifically referring to the negative side effects experienced from the medication. Choice B, 'Frequent,' is incorrect as 'adverse' does not imply how often the side effects occur but rather their nature. Choice C, 'Noticeable,' is incorrect as 'adverse' does not necessarily mean that the side effects are easily noticeable, but rather that they are harmful. Choice D, 'Constant,' is incorrect as 'adverse' does not indicate that the side effects are continuous but rather that they are negative.

Correct Answer: A

Rationale: The correct answer is A: 'It is equipped with articles.' In real estate terms, when an apartment is advertised as 'furnished', it means that the apartment comes equipped with furniture and other necessary items. This choice directly reflects the meaning of a furnished apartment. The other choices are incorrect because being furnished does not imply that the apartment has just been repainted (B), requires the first month's rent to be paid in advance (C), or includes utility bills in the rental cost (D).

Correct Answer: A

Rationale: The correct answer is 'Refrain.' 'Refrain' is synonymous with 'abstain,' meaning to hold oneself back. The other choices are incorrect. 'Indulge' means to allow oneself to enjoy the pleasure of something, 'Adhere' means to stick to or follow, and 'Eliminate' means to completely remove or get rid of.
