1. Two experiments investigating the same phenomenon produce conflicting results. What is the most appropriate next step?

• A. Ignore the conflicting results and focus on the more convincing experiment.
• B. Conduct a combined experiment incorporating elements of both.
• C. Attack the methodology of the experiment with conflicting results.
• D. Accept the more recent experiment as definitively correct.

Correct answer: C

Rationale: When faced with conflicting results from two experiments, it is important to critically evaluate the methodology of both experiments. By examining the experimental design, variables controlled for, sample sizes, and potential sources of bias, one can better understand the reasons behind the discrepancies. Attacking the methodology of the experiment with conflicting results can help identify potential flaws or limitations that may explain the differences in outcomes. This approach allows for a more informed decision on how to proceed, rather than simply ignoring or accepting one set of results over the other.

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: C

Rationale: The recommended daily intake of protein for adults to maintain healthy muscle mass is 1.5 grams per kilogram of body weight. Protein is essential for muscle repair and growth, and consuming an adequate amount helps support overall muscle health. 1 gram per kilogram of body weight is generally recommended for sedentary individuals, but for those looking to maintain or build muscle mass, a higher intake of 1.5 grams per kilogram of body weight is advised. Consuming too little protein can lead to muscle loss, while consuming too much may strain the kidneys. Therefore, 1.5 grams per kilogram of body weight strikes a balance for most adults looking to support their muscle health.

3. A ball is thrown horizontally off a cliff. Which of the following forces is responsible for its downward motion?

• A. The force of throwing
• B. Normal force from the air
• C. Tension force from the string (if used)
• D. Gravitational force

Correct answer: D

Rationale: The gravitational force is responsible for the downward motion of the ball. When the ball is thrown horizontally off a cliff, the only force acting on it in the vertical direction is the force of gravity, which pulls the ball downward towards the ground. The other forces mentioned (force of throwing, normal force from the air, tension force from the string) do not contribute to the ball's downward motion in this scenario.

4. The gland located on top of the kidneys responsible for regulating blood pressure and electrolyte balance is the:

• A. Thyroid gland
• B. Pituitary gland
• C. Adrenal gland
• D. Parathyroid gland

Correct answer: D

Rationale: The correct answer is C: Adrenal gland. The adrenal glands are located on top of the kidneys and play a crucial role in regulating blood pressure and electrolyte balance by secreting hormones such as aldosterone and cortisol. The thyroid gland (A) regulates metabolism, the pituitary gland (B) controls other endocrine glands, and the parathyroid gland (D) regulates calcium levels in the blood. Therefore, the adrenal gland is specifically responsible for the functions mentioned in the question, making it the correct choice.

5. What part of speech is the underlined word in the sentence: "He felt a growing sense of unease"?

• A. Verb
• B. Noun
• C. Adjective
• D. Adverb

Correct answer: B

Rationale: "Sense" represents a concept or feeling, making it a noun here.

6. Which sentence uses the past perfect tense correctly?

• A. By the time I arrived, the party had already begun.
• B. I wish I had studied harder for the exam.
• C. We will have finished the project by Monday.
• D. She had been waiting for hours before he finally showed up.

Correct answer: A

Rationale: Option A expresses an action ("party began") completed before another past action ("I arrived").
