Correct Answer: B

Rationale: The correct answer is 'She was going to the store.' This sentence uses the correct form of the past continuous tense, which is appropriate for describing an action in progress in the past. Choice A is the only option that uses the correct verb form. Choice C uses the present perfect tense, which is not suitable for describing a past action in progress. Choice D is incorrect as it lacks the auxiliary verb 'has' in the sentence structure.

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.

Correct Answer: A

Rationale: In the context provided, the correct answer is 'university.' The term 'university' is used to refer to higher education institutions that offer undergraduate and postgraduate degrees. While 'academy,' 'college,' and 'institute' are also types of educational institutions, 'university' is the most fitting choice here as it best aligns with the idea of completing higher education before joining the army.

Correct Answer: A

Rationale: The word 'bilateral' means having or relating to two sides. It is often used to describe something that occurs on both sides, such as bilateral symmetry in which an object is symmetrical on two sides. Choice B, 'Straight,' does not capture the meaning of bilateral. Choice C, 'Symmetrical,' while related, does not specifically convey the idea of something pertaining to two sides. Choice D, 'On one side,' is the opposite of what bilateral means.

Correct Answer: C

Rationale: The term 'invasive' refers to a procedure that involves entering the body, usually with a medical instrument or device. In the context provided, the doctor wants to try other non-invasive or less invasive options before resorting to an invasive procedure. 'Experimental' means untested or not yet proven to be effective, which aligns with the idea of exploring alternative methods before considering a more invasive approach. Choices A, B, and D are incorrect because they do not relate to the context of trying alternative procedures that are different from invasive ones.
