1. Select the meaning of the underlined word in the following sentence. Quick action kept the disease from permeating the general population.

A. Conquering
B. Wounding
C. Deterring
D. Infiltrating

Correct answer: D

Rationale: In this context, the word 'permeating' indicates the process of spreading throughout or penetrating into. 'Infiltrating' is the most appropriate synonym for this meaning, as it captures the idea of the disease spreading into the general population. 'Conquering' (Choice A) means to overcome or defeat, which is not the meaning in this context. 'Wounding' (Choice B) means to cause injury, which is not relevant to the sentence. 'Deterring' (Choice C) means to discourage or prevent, which does not fit the context of the disease spreading.

2. What does 'internal' mean?

A. Near the surface of the body
B. Located within the body
C. Outside the body
D. Far from the body

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.'

3. The ETIOLOGY of the flu epidemic of 1918 remains unknown to this day.

A. Pathology
B. Transmission
C. Etiology
D. Mortality rate

Correct answer: C

Rationale: The term 'etiology' refers to the cause or origins of a disease. In this context, the question is asking for the underlying reason or cause of the flu epidemic of 1918. Therefore, the correct answer is C. 'Etiology.' Choice A, 'Pathology,' is incorrect as it refers to the study of diseases rather than the cause itself. Choice B, 'Transmission,' is incorrect as it relates to how a disease spreads rather than its cause. Choice D, 'Mortality rate,' is incorrect as it refers to the number of deaths caused by a disease rather than the cause of the disease itself.

4. An alarm that is strident is ___________.

A. shrill
B. muted
C. constant
D. resonant

Correct answer: A

Rationale: A strident alarm is loud, harsh, and piercing. The word 'shrill' specifically denotes a high-pitched and piercing sound, which aligns well with the characteristics of a strident alarm. Therefore, 'shrill' is the most suitable answer in this context. Choices B, C, and D are incorrect because a strident alarm is not quiet (muted), unchanging (constant), or deep and full (resonant), but rather loud and harsh.

5. 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.
