1. What can one reasonably conclude from the final comment of this passage?

• A. The speaker is considering a name change.
• B. The speaker is experiencing an identity crisis.
• C. The speaker has mistakenly been looking for the wrong person.
• D. The speaker intends to continue to look for Hyde.

Correct answer: D

Rationale: The final comment in the passage indicates that Mr. Utterson intends to keep searching for Mr. Hyde, showing his determination. The passage describes how Mr. Utterson is troubled by questions about Hyde, engaging not just his intellect but also his imagination. Despite the lack of information obtained from Lanyon, Mr. Utterson continues to ponder the problem late into the night, suggesting his commitment to uncovering the mystery. Choices A, B, and C are incorrect because there is no indication in the passage that the speaker is considering a name change, experiencing an identity crisis, or mistakenly looking for the wrong person. The passage focuses on Mr. Utterson's persistent search for Hyde, emphasizing his unwavering resolve.

2. Based upon the contextual evidence provided in the passage above, what is the meaning of the term 'enterprise' in the third paragraph?

• A. Company
• B. Courage
• C. Game
• D. Cause

Correct answer: A

Rationale: 'Enterprise' here refers to a company or organization, particularly one that requires effort and initiative. In the passage, the term 'enterprise' is used in the context of establishing a Mechanic's Institution, emphasizing the involvement and support of the working man in such an organization. Choice B, 'Courage,' is incorrect as the term refers more to determination and initiative in creating and supporting the institution rather than bravery. Choice C, 'Game,' and choice D, 'Cause,' are also incorrect as they do not align with the context provided in the passage.

3. Which statement accurately describes the periodic trends in atomic radius?

• A. Increases down a group and decreases across a period
• B. Decreases down a group and increases across a period
• C. Remains constant throughout the table
• D. Fluctuates unpredictably based on individual elements

Correct answer: A

Rationale: The correct statement is that atomic radius increases down a group and decreases across a period. When moving down a group, additional electron shells increase the distance from the nucleus, leading to larger atomic radii. On the other hand, when moving across a period, the number of electron shells remains constant, but the increasing nuclear charge pulls electrons closer, resulting in smaller radii. Choice B is incorrect because atomic radius does not decrease down a group and increase across a period. Choice C is incorrect because atomic radius does not remain constant; it exhibits specific trends. Choice D is incorrect because atomic radius follows predictable trends based on the periodic table structure, rather than fluctuating unpredictably.

4. During REM sleep, which type of brain wave activity is often seen and associated with dreaming?

• A. Delta waves
• B. Alpha waves
• C. Beta waves
• D. Theta waves

Correct answer: D

Rationale: Theta waves are the correct answer as they are often seen during REM (rapid eye movement) sleep, the stage of sleep closely related to dreaming. Theta waves have a frequency of 4-7 Hz and are typically present during deep relaxation, meditation, and light sleep stages. Delta waves (choice A) are associated with deep sleep stages, not REM sleep. Alpha waves (choice B) are present during wakefulness and relaxation but not predominantly during REM sleep. Beta waves (choice C) are associated with alertness, problem-solving, and active thinking, not specifically with REM sleep or dreaming.

5. Muscle soreness after exercise is often caused by microscopic tears in muscle fibers. This is called

• A. Atrophy
• B. Hypertrophy
• C. DOMS (Delayed Onset Muscle Soreness)
• D. Spasm

Correct answer: C

Rationale: Muscle soreness after exercise is often caused by microscopic tears in muscle fibers, leading to Delayed Onset Muscle Soreness (DOMS). Atrophy refers to the wasting away of muscle tissue, hypertrophy is the increase in muscle size, and spasm is an involuntary contraction of a muscle. DOMS typically occurs 24 to 72 hours after intense exercise and is characterized by muscle stiffness, tenderness, and reduced range of motion. It is a normal response to unfamiliar or strenuous physical activity and indicates that the muscles are adapting to the workload. Therefore, the correct answer is C (DOMS) as it specifically describes the phenomenon of muscle soreness resulting from microscopic tears in muscle fibers, distinguishing it from the other choices which refer to different physiological processes or conditions.
