1. To which system do the retinas belong?

• A. skeletal system
• B. nervous system
• C. lymphatic system
• D. circulatory system

Correct answer: B

Rationale: The retinas belong to the nervous system. The retina is a layer of tissue at the back of the eye responsible for detecting light and sending visual information to the brain through the optic nerve. This process is essential for vision, which is controlled by the nervous system. Choices A, C, and D are incorrect because the retinas have no association with the skeletal, lymphatic, or circulatory systems.

2. Select the word that makes this sentence grammatically correct. The board of education ___________ to hold a special meeting.

• A. plan
• B. plans
• C. planning
• D. do plan

Correct answer: B

Rationale: In this sentence, the subject 'board of education' is singular, so the verb should also be singular to match. 'Plans' is the correct form of the verb to use with a singular subject. The correct sentence should be: 'The board of education plans to hold a special meeting.' Choices A, C, and D are incorrect because they do not agree in number with the singular subject 'board of education.' 'Plan' is plural, 'planning' is a gerund form, and 'do plan' is not the correct verb form for the subject-verb agreement in this sentence.

3. What is another word for panacea?

• A. Poison
• B. Cure
• C. Treatment
• D. Remedy

Correct answer: B

Rationale: The correct answer is B: Cure. A panacea is a remedy or cure for all diseases. While 'poison' (choice A) is the opposite of a cure, 'treatment' (choice C) is a general approach to addressing an illness rather than a universal solution, and 'remedy' (choice D) is synonymous with cure but not as closely related to the concept of a universal remedy as 'cure'.

4. How many amino acids are essential for human life?

• A. 22
• B. 20
• C. 18
• D. 24

Correct answer: B

Rationale: There are 20 essential amino acids required for human life. These amino acids cannot be synthesized by the body and must be obtained through the diet. They play crucial roles in various physiological functions and are necessary for protein synthesis and overall health. Choice A is incorrect because there are not 22 essential amino acids. Choice C is incorrect as there are more than 18 essential amino acids. Choice D is incorrect as there are not 24 essential amino acids for human life.

5. What is the meaning of 'belligerent'?

• A. retired
• B. sardonic
• C. pugnacious
• D. acclimated

Correct answer: C

Rationale: The correct answer is C, 'pugnacious.' 'Belligerent' means aggressive or combative, which aligns with the definition of 'pugnacious.' Choice A, 'retired,' is incorrect as it does not relate to the aggressive or combative nature of 'belligerent.' Choice B, 'sardonic,' means grimly mocking or cynical, which is not synonymous with 'belligerent.' Choice D, 'acclimated,' means to become accustomed to a new climate or environment, which is unrelated to the meaning of 'belligerent.'
