A. Blood pressure
B. Cervical opening
C. Birth process
D. Exhumation

Correct answer: B

Rationale: In the context provided, 'dilation' refers to the widening or opening of the cervix during labor as the woman progresses towards childbirth.

Choice D, 'Exhumation,' is unrelated and does not fit the context of the sentence.

2. What does Milieu mean?

A. A person's background
B. The environmental condition or setting
C. A person's history
D. The chemical composition

Correct answer: B

Rationale: The correct answer is B: 'The environmental condition or setting.' Milieu refers to the surroundings or environment in which a person lives or operates. Choice A ('A person's background') is incorrect as it refers more to someone's personal history rather than the external environment. Choice C ('A person's history') is also incorrect as it specifically relates to an individual's past events and experiences. Choice D ('The chemical composition') is unrelated to the meaning of milieu, which pertains to the physical or social setting.

Choices A, B, and C use 'fast' as an adjective, not an adverb. In choice A, 'fast' is describing the car, in choice B it is describing how the car drove, and in choice C it is describing the runner.

4. Select the meaning of the underlined word in the following sentence. The chemicals in plastic containers may be deleterious to children’s health.

A. Harmful
B. Deleting
C. Delightful

Correct answer: A

Rationale: The word 'deleterious' means causing harm or damage. In this context, the sentence implies that the chemicals in plastic containers can be harmful to children's health. Therefore, the correct meaning of the underlined word is 'harmful,' making option A the most suitable choice. Option B 'Deleting' is incorrect because it refers to removing or erasing, which does not fit the context. Option C 'Delightful' is incorrect as it means causing great pleasure or delight, the opposite of the intended meaning. Option D 'Inoffensive' is incorrect as it means not causing any harm or annoyance, which is contrary to the negative impact described in the sentence.

5. What is the term for the lower surface of a structure?
