1. Julia is writing an essay about the influence of technology on interpersonal relationships. Which of the following sentences would NOT be a relevant supporting detail?

• A. Studies show that the more teenagers engage in social media, the less they engage with their peers.
• B. College students study and work on homework an average of 4-6 hours a day.
• C. Use of technology such as smartphones can lead to a lack of engagement in conversations.
• D. Some psychologists think that watching TV activates the same part of the brain as having an in-depth conversation.

Correct answer: B

Rationale: In an essay focusing on the impact of technology on interpersonal relationships, details about college students' study habits and homework workload are not directly related to the influence of technology on relationships. Choices A, C, and D are more relevant as they directly address the impact of technology, such as social media engagement, smartphone usage affecting conversations, and the comparison between TV-watching and brain activity during conversations.

2. What is the primary function of Bartholin's glands?

• A. Secretes hormones that help the body respond to stress
• B. Provide lubrication for the vagina
• C. Helps control growth and development of the body
• D. Stimulate the development of T cells

Correct answer: B

Rationale: Bartholin's glands are two small glands located on each side of the vaginal opening. Their primary function is to secrete fluids that help lubricate the vagina during sexual arousal. This lubrication helps to reduce friction and discomfort during sexual activity, making intercourse more comfortable and pleasurable. Choices A, C, and D are incorrect because Bartholin's glands do not secrete hormones to respond to stress, control growth and development, or stimulate the development of T cells. Their main role is specifically related to vaginal lubrication.

3. Select the book title that does not contain a preposition.

• A. The Man in the Brown Suit
• B. The Secret of Chimneys
• C. Murder on the Orient Express
• D. And Then There Were None

Correct answer: D

Rationale: The correct answer is 'D' - 'And Then There Were None.' This title does not contain a preposition. Prepositions are words that show the relationship of a noun or pronoun to another word in the sentence. In this title, 'And,' 'Then,' 'There,' and 'None' are not prepositions; they are conjunctions and pronouns. Choices A, B, and C all contain prepositions: 'in,' 'of,' and 'on,' respectively. Therefore, they are incorrect answers for this question.

4. What happens to the frequency of a wave if its wavelength decreases while the speed remains constant?

• A. Frequency decreases
• B. Frequency increases
• C. Frequency remains constant
• D. Frequency becomes zero

Correct answer: B

Rationale: The correct answer is B: Frequency increases. Frequency and wavelength are inversely proportional in a wave with a constant speed. When the wavelength decreases while the speed remains constant, the frequency must increase to maintain the constant speed of the wave. This relationship is governed by the equation: speed = frequency x wavelength. Choice A is incorrect as frequency increases when wavelength decreases. Choice C is incorrect as the frequency changes in this scenario. Choice D is incorrect as the frequency does not become zero but increases when the wavelength decreases.

5. What is hydroxyapatite?

• A. A mixture of minerals such as calcium and phosphorus that strengthen the collagen matrix of bone.
• B. The structural unit of a bone that runs the length of the bone.
• C. The covering of bones at the point of articulation to prevent grinding.
• D. The lightest portion of a long bone and concentrated at the ends.

Correct answer: A

Rationale: Hydroxyapatite is a mineral compound composed of calcium and phosphorus that plays a crucial role in strengthening the collagen matrix of bones, contributing to their structural integrity and hardness. It is a key component of bone tissue and provides the mineralization necessary for bone strength and density. Choice B is incorrect because the structural unit of a bone is the osteon or Haversian system, not hydroxyapatite. Choice C is incorrect as it describes cartilage, not hydroxyapatite. Choice D is incorrect as it refers to the epiphysis, which is not synonymous with hydroxyapatite.
