1. Follow these instructions in chronological order to transform the word into something new. What new word has been spelled?

• A. TON
• B. THIN
• C. TIN
• D. TAN

Correct answer: C

Rationale: To transform the word LOATHING into something new, we need to follow the instructions in chronological order, which is to remove letters. Starting with L-O-A-T-H-I-N-G, if we remove the letters in the order given, we are left with T-I-N, which spells the word 'TIN.' This makes choice C the correct answer. Choices A, B, and D do not follow the specific sequence of removing letters from the original word LOATHING, so they are incorrect.

2. Which of the following terms refers to a muscle twitch, a single forceful contraction of a muscle fiber?

• A. Tetanus
• B. Tremor
• C. Fasciculation
• D. Rigidity

Correct answer: C

Rationale: The correct term for a muscle twitch, a single forceful contraction of a muscle fiber, is 'Fasciculation' (choice C). Fasciculation specifically describes this phenomenon. 'Tetanus' (choice A) refers to sustained muscle contraction, 'Tremor' (choice B) indicates a shaky or quivering movement, and 'Rigidity' (choice D) denotes stiffness or inflexibility in muscles. Therefore, choices A, B, and D are incorrect in the context of a single forceful contraction of a muscle fiber.

3. What is the process of separating a mixture based on the different boiling points of its components called?

• A. Filtration
• B. Chromatography
• C. Distillation
• D. Centrifugation

Correct answer: C

Rationale: Distillation is the process of separating a mixture based on the different boiling points of its components. During distillation, the mixture is heated to vaporize the component with the lowest boiling point first. The vapor is then cooled and condensed back into a liquid, allowing for the collection of fractions with different boiling ranges. This technique is effective for separating components that have significantly different boiling points. Filtration (Choice A) is a method used to separate solids from liquids or gases using a filter medium. Chromatography (Choice B) is a technique used to separate components of a mixture based on their differential affinities to a stationary phase and a mobile phase. Centrifugation (Choice D) is a process of separating particles from a solution based on differences in size, shape, density, and viscosity by spinning the mixture at high speeds.

4. Which of the following structures is responsible for transmitting electrical impulses in the nervous system?

• A. Neuron
• B. Axon
• C. Myelin
• D. Dendrite

Correct answer: A

Rationale: The correct answer is A: Neuron. Neurons are specialized cells that transmit electrical impulses in the nervous system. While the axon is the part responsible for conducting these impulses over long distances, it is the neuron as a whole that is ultimately responsible for transmitting electrical impulses. Myelin is a fatty substance that surrounds and insulates axons, speeding up signal transmission. Dendrites, on the other hand, receive signals from other neurons. Therefore, although the axon plays a significant role in transmission, the neuron is the fundamental unit responsible for transmitting electrical impulses in the nervous system.

5. What is the purpose of the use of repetition in the following passage? It was a night of little ease to his toiling mind, toiling in mere darkness and besieged by questions.

• A. It serves as a demonstration of Mr. Lanyon's mental state.
• B. It highlights the church bells mentioned in the story.
• C. It reflects Mr. Utterson's ambivalence.
• D. It emphasizes Mr. Utterson's anguish in failing to identify Hyde's whereabouts.

Correct answer: D

Rationale: The repetition in the passage emphasizes Mr. Utterson's mental struggle and persistence as he grapples with his thoughts and questions. It conveys the intensity of his anguish and frustration in trying to identify Hyde's whereabouts, rather than reflecting Mr. Lanyon's or Mr. Utterson's ambivalence. The mention of church bells is not relevant to the passage, making choice B incorrect. Therefore, the correct answer is D, as the repetition underscores Mr. Utterson's emotional turmoil and his desperate search for answers.
