1. If a product's original price is $80 and it is discounted by 20%, what is the final price?

• A. 64
• B. 60
• C. 70
• D. 66

Correct answer: A

Rationale: To find the discounted price, you first calculate 20% of the original price: 20% of $80 is $16. Subtracting this discount amount from the original price gives the final price: $80 - $16 = $64. Therefore, the final price after a 20% discount on a product originally priced at $80 is $64. Choice B, $60, is incorrect because it does not account for the correct discount amount. Choice C, $70, is incorrect as it does not reflect the reduction due to the 20% discount. Choice D, $66, is incorrect as it miscalculates the discounted price.

2. What is the valve that prevents blood from flowing back from the left ventricle into the left atrium?

• A. Tricuspid valve
• B. Mitral valve
• C. Aortic valve
• D. Pulmonic valve

Correct answer: B

Rationale: The correct answer is the Mitral valve. The mitral valve is located between the left atrium and the left ventricle of the heart. Its function is to prevent the backflow of blood from the left ventricle into the left atrium during ventricular contraction. Choice A, the Tricuspid valve, is incorrect as it is located between the right atrium and right ventricle. Choice C, the Aortic valve, and Choice D, the Pulmonic valve, are also incorrect as they are involved in the circulation of blood leaving the heart rather than preventing backflow within the atria and ventricles.

3. Which of the following sentences contains a correct example of subject-verb agreement?

• A. All of the board members are in agreement on the issue.
• B. Each of the students was concerned about the test scores for the final exam.
• C. Neither of the children is at home right now.
• D. Any of the brownie recipes is perfect for the bake sale.

Correct answer: A

Rationale: The correct answer is A. In this sentence, the subject 'all of the board members' is plural, and the verb 'are' agrees with it. In choice B, 'each of the students' is singular, so the verb should be 'was' instead of 'were.' Choice C should use 'is' instead of 'are' since 'neither of the children' is singular. In choice D, 'any of the brownie recipes' is singular, so 'is' should be used instead of 'are.' Therefore, only choice A demonstrates proper subject-verb agreement.

4. Which of the following describes the path through which air moves during inhalation?

• A. mouth/nose > pharynx > larynx > trachea > bronchi > bronchioles > alveoli
• B. bronchioles > alveoli > bronchi > larynx > pharynx > lungs
• C. mouth/nose > bronchi > bronchioles > alveoli > lungs > trachea
• D. alveoli > bronchioles > lungs > bronchi > trachea > larynx > pharynx > mouth/nose

Correct answer: A

Rationale: The correct path through which air moves during inhalation is from the mouth/nose > pharynx > larynx > trachea > bronchi > bronchioles > alveoli. This sequence accurately represents the typical route air takes as it travels from the external environment into the lungs to facilitate gas exchange in the alveoli. Choice B is incorrect as it reverses the order of bronchioles and alveoli. Choice C is incorrect as it starts with mouth/nose but then incorrectly lists lungs before trachea. Choice D is incorrect as it reverses the entire sequence of the respiratory pathway, starting with alveoli instead of mouth/nose.

5. The mechanic used a computer to perform the diagnostic tests. Which of the following sentences most clearly and concisely conveys the same meaning?

• A. While performing diagnostic tests on the car, the mechanic used a computer.
• B. Although the mechanic used a computer, he performed diagnostic tests on the car.
• C. Because he used a computer, the mechanic performed diagnostic tests on the car.
• D. The mechanic used a computer to perform diagnostic tests on the car.

Correct answer: D

Rationale: Choice D correctly conveys that the mechanic used a computer to perform diagnostic tests on the car. It is concise and clear, effectively communicating the main point without unnecessary details. Choices A, B, and C include unnecessary repetition or do not convey the information as clearly as choice D. For instance, choice A adds unnecessary repetition by mentioning 'performing diagnostic tests' twice, while choices B and C introduce additional clauses that make the sentence less concise and direct.
