1. Which sentence uses the correlative conjunction 'either/or' correctly?

• A. You can either come to the party or stay home.
• B. Either she will go to the concert, or he will.
• C. I'm not sure whether I should go swimming or running.
• D. He likes both pizza and pasta, so he can have either.

Correct answer: A

Rationale: Option A uses the correlative conjunction 'either/or' correctly by presenting two exclusive options. The structure 'either...or' is used to show a choice between two alternatives, and in this sentence, it clearly presents the options of coming to the party or staying home. Choice B incorrectly separates the options with a comma after 'either,' disrupting the correlative conjunction pair. Choice C uses 'whether' instead of 'either/or,' which changes the meaning and structure. Choice D uses 'either' incorrectly, as it should be followed by 'or' to form the correlative pair.

2. What is the recommended daily intake of protein for adults to maintain healthy muscle mass?

• A. 0.5 grams per kilogram of body weight
• B. 1 gram per kilogram of body weight
• C. 1.5 grams per kilogram of body weight
• D. 2 grams per kilogram of body weight

Correct answer: B

Rationale: The recommended daily intake of protein for adults to maintain healthy muscle mass is typically around 1 gram per kilogram of body weight. This amount can vary based on individual factors such as activity level, age, and overall health status. Consuming an adequate amount of protein is essential for muscle repair and growth, as well as overall health and functioning of the body. Choices A, C, and D are incorrect because they suggest protein intake levels that are either too low (A) or unnecessarily high (C and D) for maintaining healthy muscle mass. Excessive protein intake can strain the kidneys and may not provide additional benefits for muscle health beyond the recommended levels.

3. What is the fatty sheath that insulates some nerve fibers and speeds up signal transmission called?

• A. Myelin sheath
• B. Dura mater
• C. Pia mater
• D. Arachnoid mater

Correct answer: A

Rationale: The correct answer is A: Myelin sheath. The myelin sheath is a fatty layer that surrounds and insulates some nerve fibers, facilitating the rapid transmission of signals along the nerve fibers. Choices B, C, and D (Dura mater, Pia mater, and Arachnoid mater) are layers of the meninges, protective membranes that surround the brain and spinal cord. The primary function of the meninges is to protect and support the central nervous system, not to insulate nerve fibers for signal transmission.

4. How does the author distinguish between different groups of insects mentioned in the passage?

• A. By describing the specific characteristics and adaptations of each insect group.
• B. By grouping them based on their habitat into aquatic and aerial categories.
• C. By explaining the stages of development each insect undergoes.
• D. By identifying their habitats and the environments they are adapted to.

Correct answer: B

Rationale: The author distinguishes between different groups of insects based on their habitat, categorizing them into aquatic and aerial categories. The passage mentions how some insects spend time under water while others live in the air, emphasizing the distinction between aquatic and aerial habitats. Therefore, choice B is correct. Choices A, C, and D are incorrect because the passage does not focus on describing the specific characteristics, adaptations, stages of development, or environments of the insects, but rather on their habitat and lifestyle.

5. What best describes Samuel's sample size?

• A. The sample is biased because it has firsthand experience.
• B. The sample contains too few members to draw meaningful conclusions.
• C. The sample contains too many members to make specific claims.
• D. The sample is unbiased and of appropriate size.

Correct answer: B

Rationale: Samuel's sample size of 24 students is too small to draw generalizable conclusions about a larger population. While his observations are based on firsthand experience, the sample size is inadequate to make meaningful claims about the relationship between parental involvement and academic success for all students. Choice A is incorrect because bias is not related to sample size but rather the way data is collected. Choice C is incorrect as having too many members would not hinder understanding specifics, but rather provide a more comprehensive view. Choice D is incorrect as the sample size is too small to be considered appropriately sized for making broad claims.
