Correct Answer: B

Rationale: The correct definition of 'depress' is to press downward. This term is commonly used to describe pushing something downward or making something lower in position or level. Choice A, 'To push forward,' is incorrect as 'depress' does not involve moving something forward. Choice C, 'To remove,' is incorrect as 'depress' does not entail taking something away. Choice D, 'To elevate,' is incorrect as it is the opposite of what 'depress' means.

Correct Answer: B

Rationale: In real estate, when an apartment is described as 'furnished,' it means that it comes equipped with furniture. This typically includes essential items like beds, sofas, dining tables, and more. Therefore, 'Equipped with furniture' is the correct meaning of 'furnished' in this context. Choices A, C, and D are incorrect because being 'furnished' specifically refers to the presence of furniture in the apartment, not renovation status, utilities, or decor style.

Correct Answer: D

Rationale: The correct answer is 'D: Sunken.' Concave refers to a surface or shape that curves inward, while 'sunken' is the closest synonym, also indicating something that is depressed or hollowed inward. Choice 'B: Convex' is incorrect as it is the opposite of concave, representing a shape that bulges outward. Choices 'A: Sunburned' and 'C: Puffed out' do not relate to the concept of concave shapes.

Correct Answer: B

Rationale: Internal means located within the body. When something is described as internal, it refers to being inside the body or contained within the boundaries of an organism. Choices A, C, and D are incorrect as they describe locations that are either near the surface, outside, or far from the body, respectively, which are not the meanings of 'internal.'

Correct Answer: A

Rationale: The correct answer is A, 'While they were sleeping.' This is an incomplete sentence as it lacks a main clause. A complete sentence should have both a subject and a predicate to express a complete thought. In this case, the subordinating conjunction 'while' introduces a dependent clause that needs to be connected to an independent clause to form a complete sentence. Choices B, C, and D are complete sentences as they each contain a subject and a predicate, expressing a complete thought.
