1. Which type of muscle is responsible for moving the skeleton?

Correct answer: B

Rationale: Skeletal muscle is the correct answer as it is responsible for moving the skeleton. Skeletal muscles are under voluntary control, meaning they can be consciously controlled by the individual. Cardiac muscle (Choice A) is found in the heart and is responsible for pumping blood, not moving the skeleton. Smooth muscle (Choice C) is found in internal organs and is responsible for involuntary movements like digestion. Voluntary muscle (Choice D) is not a specific type of muscle; it refers to muscles that can be consciously controlled, which includes skeletal muscles.

2. An uncharged atom has an electron configuration of 1s² 2s² 2p⁶ 3s² and a mass number of 14. How many protons does it have?

Correct answer: B

Rationale: The number of protons in an atom is determined by the atomic number, which is equal to the number of protons in the nucleus. The electron configuration given corresponds to carbon (C) with 6 protons. The atomic number of an element is the same as the number of protons in its nucleus, so in this case, the atom has 6 protons. Choices A, C, and D are incorrect because they do not correspond to the correct number of protons for an atom with the given electron configuration and mass number. Therefore, option B, 6 protons, is the correct answer.

3. What is the main verb tense in the following sentence? 'She had already left before I arrived.'

Correct answer: D

Rationale: The correct answer is 'D, Past perfect tense.' In the sentence provided, the verb 'had left' is in the past perfect tense. The past perfect tense is used to indicate an action that was completed before another past action, which in this case is 'arrived.' Therefore, the main verb tense in the sentence is past perfect. Choices A, B, and C are incorrect because the sentence does not contain present, past, or future tense verbs as the main verb. Instead, the main verb 'left' is in the past perfect tense, showing an action completed before another past event.

4. The pancreas secretes digestive enzymes into the small intestine. What enzyme breaks down proteins into amino acids?

Correct answer: D

Rationale: Trypsin is the correct enzyme that breaks down proteins into amino acids. It is produced by the pancreas and released into the small intestine to facilitate protein digestion. Pepsin is an enzyme from the stomach that also breaks down proteins, amylase targets carbohydrates, and lipase works on fats. In this context, since the question specifies the pancreas and small intestine, the correct answer is Trypsin as it is the pancreatic enzyme responsible for protein breakdown in the small intestine.

5. Which of the following would be a useful source of information to determine the validity of the argument presented in this passage?

Correct answer: D

Rationale: Choice D is the correct answer as it can provide evidence to support the claim made in the passage that high school graduates who studied a foreign language are more likely to be accepted to college. This choice aligns with the argument presented in the passage, making it a useful source. Choices A and C focus on opinions rather than concrete evidence of the impact of studying a foreign language on future success. Choice B is not directly relevant as it talks about learning a second language at home, while the passage specifically discusses the importance of studying a foreign language in high school.
