Which sentence correctly uses the word 'affect'?

Correct Answer: B

Rationale: The correct use of 'affect' is to show influence or make a difference. In this context, 'The noise did not affect his sleep' is the correct usage as noise can impact one's ability to sleep. Choice A is incorrect as 'affect' is commonly confused with 'effect.' Choice C is incorrect as 'affect' is not typically used to refer to the impact of light on eyes. Choice D is incorrect as 'affect' is not typically used to describe the impact of weather on mood.

Correct Answer: A

Rationale: The correct answer is A: 'She had one goal: to win the race.' This sentence uses a colon to introduce the purpose or explanation that follows. It is a grammatically correct use of a colon. Choice B is incorrect as the colon is not needed after 'needs'; a list of items follows, which does not require a colon. Choice C is a simple statement of time and does not require a colon. Choice D is also incorrect since a colon is not suitable after 'bought'; the items bought are listed without the need for a colon.

Correct Answer: B

Rationale: The correct answer is B: 'Guarded.' Circumspect means to be cautious or guarded. In this context, being circumspect with patient records implies being careful and cautious in handling them, maintaining confidentiality and privacy. Choices A, C, and D are incorrect because circumspect does not mean acting carelessly, reckless, or neglecting; instead, it suggests being watchful and discreet.

Correct Answer: B

Rationale: The correct answer is B, 'Emetic.' An emetic is a medication specifically designed to induce vomiting. This helps the body expel toxic substances or clear the stomach. Choice A, 'Laxative,' aids in relieving constipation by promoting bowel movements, not inducing vomiting. Choice C, 'Vaccine,' is a substance used to stimulate the immune system against specific diseases, not to induce vomiting. Choice D, 'Analgesic,' refers to a medication used to relieve pain, not to induce vomiting. Therefore, options A, C, and D are incorrect in the context of inducing vomiting.

Correct Answer: A

Rationale: The correct answer is A: 'Complaining.' Querulous means to be habitually complaining or whining. It is characterized by a tendency to find fault or raise petty objections. This behavior aligns with the definition of being querulous. Choices B, C, and D are incorrect as they do not reflect the meaning of querulous. Sleeping, shouting, or crying are not behaviors typically associated with being querulous.
