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: A

Rationale: Choice A, 'It is equipped with articles of furniture,' correctly defines a furnished apartment. When an apartment is advertised as furnished, it means that it comes with essential furniture such as beds, tables, chairs, and other necessary items. Choice B is incorrect because being furnished does not necessarily relate to the decor level of the apartment. Choice C is incorrect as utilities like water and electricity are not typically included in the term 'furnished.' Choice D is also incorrect because being furnished does not imply that the apartment is fully renovated, which refers to structural improvements rather than furniture.

Correct Answer: B

Rationale: The correct answer is B: 'Reddened or ruddy appearance.' When someone is flushed, it means they have a red or ruddy complexion, often due to embarrassment, anger, or a physical reaction. Choices A, C, and D are incorrect because 'flushed' specifically refers to a red or ruddy appearance, not swelling, discoloration, or paleness.

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: 'This door will remain unlocked when the office is occupied.' This choice provides a clear and grammatically correct revision of the original sentence. Choice B is incorrect due to the missing 'will' before 'remain' and 'the' before 'office.' Choice C is incorrect as it does not include 'the office,' making it less specific. Choice D is incorrect as it uses 'while' instead of 'when,' changing the intended meaning.
