Correct Answer: D

Rationale: The correct answer is D. The paragraph explains that harsh voice qualities usually result from too much tension in the throat and jaw. It further discusses how tension tightens muscles, leading to unpleasant voice tones. While the paragraph addresses the issue of harsh voices, it does not mention that only some men have harsh voices (choice A) or that relaxed people often exhibit this quality (choice B). Additionally, the paragraph does not touch upon whether everyone finds harsh voices irritating (choice C), only stating that not everyone may be bothered by it.

Correct Answer: A

Rationale: In the provided extract, the term 'concomitant' is used to describe problems associated with alcohol abuse, such as the individual becoming alcoholic, contribution to highway deaths by drunken drivers, and spousal and child abuse. Therefore, in this context, 'concomitant' means accompanying, or going along with something else. The other choices of 'Quiet,' 'Frustrated,' and 'Prefer low-pitched tones' do not align with the meaning of 'concomitant' as used in the paragraph.

Correct Answer: A

Rationale: The word 'composed' means to be made up of or to consist of something. In the provided extract, it describes how a single drop of water is composed of an oxygen atom and two hydrogen atoms. Therefore, the correct answer is 'To consist of.' Choice B, 'To break apart,' is incorrect as it is the opposite of 'composed.' Choice C, 'To mix with other elements,' is incorrect as 'composed' refers to being made up of specific components, not mixed with others. Choice D, 'To heat up,' is unrelated to the meaning of 'composed' in this context.

Choices A, B, and C are incorrect as Thailand is not located in Africa, Europe, or South America.

Choice C is incorrect as ponds and lakes are not stated to be formed by runoff. Choice D is incorrect as ponds and lakes are not formed by condensation.
