1. Which of the following sentences distracts the reader from the main focus of the passage?

• A. Malory's work, which is believed to be largely a translation of older French stories, was written in prose style.
• B. Instead of embracing the romance angle, however, Malory focused more on the moral elements within these stories.
• C. In Tennyson's work, Arthur chooses to forgive Guinevere, and she chooses to spend the rest of her days doing good works in a convent.
• D. Charles Dickens is remembered for doing the same thing in his novels about the abuses of lower-class children in Victorian England.

Correct answer: D

Rationale: The focus of the passage is on Malory and Tennyson and their interpretations of the Arthurian legends. The mention of Charles Dickens in choice D is irrelevant and distracts the reader from the main discussion. While the other choices discuss Malory's prose style, his focus on moral elements, and Tennyson's approach to the Arthurian stories, choice D brings in a comparison to Charles Dickens and his novels about lower-class children in Victorian England. This mention of Dickens does not directly relate to the main theme of the passage, making it the correct answer as the distracting sentence.

2. What is the primary composition of the stratum corneum, the outermost layer of the epidermis?

• A. Keratinized dead cells
• B. Melanocytes
• C. Langerhans cells
• D. Merkel cells

Correct answer: A

Rationale: The stratum corneum, the outermost layer of the epidermis, is primarily composed of keratinized dead cells. These cells are flattened, fully keratinized, and lack nuclei, serving a protective function for the skin. Melanocytes are responsible for producing melanin, providing skin pigmentation. Langerhans cells are involved in the immune response within the skin. Merkel cells are associated with sensory functions in the skin, particularly in touch sensations. Therefore, the correct answer is A as it accurately reflects the main constituent of the stratum corneum, which acts as a barrier against external factors.

3. Which of the following is the smallest part of an element that can still be recognized as that element?

• A. Electron
• B. Proton
• C. Neutron
• D. Atom

Correct answer: D

Rationale: An atom is the smallest unit of matter that retains the chemical properties of an element. It consists of a nucleus containing protons and neutrons, surrounded by electrons that orbit the nucleus. The number of protons in the nucleus defines the atomic number of the element, and the number of neutrons determines the isotope of the element. While electrons, protons, and neutrons are fundamental particles, an atom as a whole is the smallest part of an element that maintains its unique identity. Electrons are negatively charged particles orbiting the nucleus, protons are positively charged particles in the nucleus, and neutrons are neutral particles in the nucleus. Therefore, the correct answer is 'D: Atom.'

4. Which of the following terms describes the enlargement of an organ or tissue?

• A. Dystrophy
• B. Atrophy
• C. Hypertrophy
• D. Eutrophy

Correct answer: C

Rationale: Hypertrophy refers to the enlargement of an organ or tissue, typically due to an increase in the size of individual cells. This can occur in response to increased workload, hormonal stimulation, or other factors. On the other hand, dystrophy refers to the degeneration and deterioration of tissue, atrophy describes the decrease in the size of an organ or tissue, and eutrophy denotes a state of normal nutrition or growth. Therefore, the correct answer is 'Hypertrophy' as it specifically relates to the increase in size or volume of an organ or tissue.

5. What is the term for a hydrocarbon chain with no double or triple bonds between carbon atoms?

• A. Saturated
• B. Unsaturated
• C. Aromatic
• D. Alkene

Correct answer: A

Rationale: A saturated hydrocarbon chain contains only single bonds between carbon atoms, making it 'saturated' with hydrogen atoms. Therefore, the correct answer is choice A, 'Saturated.' Choice B, 'Unsaturated,' is incorrect because it refers to hydrocarbon chains with double or triple bonds. Choice C, 'Aromatic,' is not the correct term for a hydrocarbon chain without double or triple bonds; it describes a specific type of cyclic and conjugated hydrocarbon structure. Choice D, 'Alkene,' is also incorrect as it specifically indicates a hydrocarbon chain with at least one double bond between carbon atoms.
