1. What is stated in the passage about Sleep Apnea?

• A. Sleep apnea causes chronic illness.
• B. Sleep apnea affects intellectual abilities.
• C. Sleep apnea leads to early death.
• D. Sleep apnea causes breathing interruptions.

Correct answer: D

Rationale: The correct answer is 'D: Sleep apnea causes breathing interruptions.' The passage explicitly mentions sleep apnea as a condition where an individual stops breathing during sleep, indicating breathing interruptions. Choice A is incorrect because the passage does not directly state that sleep apnea causes chronic illness. Choice B is incorrect because the passage discusses how lack of sleep affects intellectual abilities but does not specifically attribute this to sleep apnea. Choice C is incorrect as the passage does not mention sleep apnea leading to early death. Therefore, the most accurate statement about sleep apnea based on the passage is that it causes breathing interruptions.

2. Select the word that makes this sentence grammatically correct. Our subcommittee ___________ on the fourth Wednesday of each month.

• A. meet
• B. meets
• C. meeting
• D. are meeting

Correct answer: B

Rationale: The word 'subcommittee' is singular, so the correct verb to use is 'meets' as it agrees with the singular subject. 'Meets' is the present tense form of the verb that matches a singular subject. Choice A 'meet' is incorrect as it is the plural form of the verb. Choice C 'meeting' is a gerund and does not fit the sentence structure. Choice D 'are meeting' is incorrect as 'are' is not the correct auxiliary verb to pair with 'subcommittee'.

3. The sum of all chemical reactions that occur in an organism is:

• A. product
• B. respiration
• C. metabolism
• D. synthesis

Correct answer: C

Rationale: Metabolism is the sum of all chemical reactions that occur within an organism to maintain life. It involves all the processes that break down molecules to release energy (catabolism) and build new molecules to support growth and maintenance (anabolism). Respiration refers specifically to the process of generating energy from the breakdown of glucose molecules. Synthesis is the creation of complex molecules from simpler ones. Therefore, metabolism is the most comprehensive term that encompasses all these processes within an organism.

4. The order of operations (PEMDAS) dictates the sequence for evaluating mathematical expressions. If a = 2 and b = -3, what is the value of 3a^2 - 2ab + b^2?

• A. -3
• B. 0
• C. 33
• D. 15

Correct answer: C

Rationale: Given expression: 3a^2 - 2ab + b^2. Substitute the values of a and b: 3(2)^2 - 2(2)(-3) + (-3)^2 = 3(4) + 12 + 9 = 12 + 12 + 9 = 24 + 9 = 33. Therefore, the value of the expression is 33, which corresponds to option C. Options A, B, and D are incorrect as they do not accurately evaluate the expression with the given values of a and b.

5. Which fibrous connective tissue attaches muscles to bones?

• A. Tendons
• B. Ligaments
• C. Cartilage
• D. Fascia

Correct answer: A

Rationale: Tendons are fibrous connective tissues that attach muscles to bones, allowing the transmission of forces generated by muscles and facilitating movement at joints. Ligaments, on the other hand, connect bones to other bones, providing stability. Cartilage is a firm, flexible connective tissue found in joints and the respiratory tract. Fascia surrounds muscles, groups of muscles, blood vessels, and nerves, offering support and protection. Therefore, the correct answer is tendons as they specifically connect muscles to bones.
