1. What does Collusion refer to?

A. Agreement
B. Conspiracy
C. Misunderstanding
D. Honesty

Correct answer: B

Rationale: Collusion refers to a secret agreement or conspiracy, often for deceitful or illegal purposes. While choices A, C, and D may involve some level of agreement or understanding, collusion specifically implies a secretive and usually dishonest arrangement, making choices A, C, and D incorrect in this context.

2. What is the grammatical category of the term 'biologists' in the sentence 'Most wildlife biologists disapprove of crossbreeding wolves and dogs'?

A. Adjective
B. Noun
C. Verb
D. Conjunction

Correct answer: B

Rationale: 'Biologists' is a noun in the sentence, referring to a group of people who study wildlife and their behaviors. In this context, 'biologists' is not describing or modifying another noun, making it a noun itself. Therefore, options A, C, and D are incorrect.

3. Which term best describes a synthetic drug?

A. man-made
B. phony
C. atypical
D. futile

Correct answer: A

Rationale: A synthetic drug is one that is artificially created in a laboratory setting rather than occurring naturally. The term 'man-made' accurately describes this process. Choices B, C, and D are incorrect. 'Phony' means fake or fraudulent, not specifically related to synthetic drugs. 'Atypical' means unusual or not typical, which doesn't directly relate to how synthetic drugs are made. 'Futile' means pointless or ineffective, which is not a characteristic of synthetic drugs.

4. 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.

5. When a symptom is exacerbated, it is ___________.

A. not dangerous
B. disfiguring
C. painful
D. made worse

Correct answer: D

Rationale: When a symptom is exacerbated, it means that it is made worse or intensified beyond its usual level of severity. This can lead to increased discomfort, pain, or other negative effects associated with that particular symptom. Choice A is incorrect because exacerbation does not imply that the symptom is not dangerous. Choice B is incorrect as exacerbation does not necessarily mean disfiguring. Choice C is incorrect as exacerbation does not always specifically refer to pain, but to any worsening of a symptom.
