1. If you go to the market, please pick up some beef, carrots, and celery, and I will make some of that delicious stew we had last week. Which comma should be removed in the sentence above?

• A. The comma after the word 'market'
• B. The comma after the word 'beef'
• C. The comma after the word 'celery'
• D. The comma after the word 'delicious'

Correct answer: D

Rationale: The comma after 'delicious' is unnecessary as it separates the adjective 'delicious' from the noun 'stew'. In this case, 'delicious' is describing the type of stew, so the comma should be removed to maintain correct sentence structure. The other commas in the sentence are correctly used to separate items in a list and after introductory phrases, making them necessary for clarity and grammatical correctness.

2. What number is equivalent to -3 + 2 * 8 + 3?

• A. 11
• B. 31
• C. 28
• D. 80

Correct answer: B

Rationale: To solve this expression, we first follow the order of operations (PEMDAS/BODMAS). According to this rule, we start by multiplying 2 by 8, which equals 16. Then, we add -3 and 3 to get 0. Finally, adding 0 to 16 gives us the correct answer of 16. The correct answer is B. Choice A (11) results from adding all the numbers without considering the multiplication first. Choice C (28) is the result of adding all the numbers without considering any operations. Choice D (80) is incorrect as it does not correctly follow the order of operations.

3. Which of the following organs is responsible for detoxifying chemicals and metabolizing drugs?

• A. Kidneys
• B. Liver
• C. Heart
• D. Pancreas

Correct answer: B

Rationale: The correct answer is B: Liver. The liver plays a crucial role in detoxifying chemicals and metabolizing drugs. It also produces bile for digestion. The liver contains enzymes that help metabolize drugs and toxins, making them easier for the body to eliminate. The kidneys are primarily responsible for filtering blood and regulating fluid balance, the heart's main function is to pump blood, and the pancreas produces digestive enzymes and hormones like insulin, but they do not have the primary function of detoxifying chemicals and metabolizing drugs.

4. What is the correct plural of chair?

• A. Chair
• B. Chairs
• C. Chaires
• D. Chairies

Correct answer: B

Rationale: The correct plural form of 'chair' is 'chairs,' following the regular pluralization rule by adding 's.' Choices C and D, 'Chaires' and 'Chairies,' are incorrect because they do not follow the standard English pluralization rule. Choice A, 'Chair,' is the singular form and not the plural form of the word.

5. What is the function of the myelin sheath in a neuron?

• A. To transmit electrical impulses
• B. To insulate and speed up electrical signals
• C. To produce neurotransmitters
• D. To protect the neuron from damage

Correct answer: B

Rationale: The myelin sheath serves to insulate neurons and accelerate the transmission of electrical signals along the axon. This insulation helps in the efficient conduction of nerve impulses by preventing signal loss or leakage. Choice A is incorrect because the myelin sheath does not transmit electrical impulses itself but rather helps in the conduction. Choice C is incorrect as the myelin sheath is not responsible for producing neurotransmitters. Choice D is also incorrect as the primary function of the myelin sheath is not to protect the neuron from damage. Therefore, the correct answer is B, as it accurately describes the function of the myelin sheath in a neuron.
