1. Which of the following words is an exception to a common spelling rule?

• A. achievement
• B. operation
• C. changeable
• D. deplorable

Correct answer: C

Rationale: The correct answer is 'C: changeable.' This word is an exception to a common spelling rule where it retains the 'e' when adding the suffix '-able.' In contrast, choices A, B, and D follow standard spelling rules without exceptions.

2. What is 0.025 mg in mcg?

• A. 25 mcg
• B. 250 mcg
• C. 2.5 mcg
• D. 0.25 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 because there are 1000 micrograms in a milligram. Therefore, 0.025 mg x 1000 = 25 mcg. This means that the correct answer is A, 25 mcg. Choice B, 250 mcg, is incorrect because it incorrectly multiplies by 10 instead of 1000. Choice C, 2.5 mcg, is incorrect as it inaccurately divides the value by 10. Choice D, 0.25 mcg, is also incorrect as it divides the value by 100 instead of multiplying by 1000.

3. What kind of error is present in the following sentence? This summer, I'm planning to travel to Italy, take a Mediterranean cruise, go to Pompeii, and eat a lot of Italian food.

• A. Parallelism
• B. Sentence fragment
• C. Misplaced modifier
• D. Subject-verb agreement

Correct answer: A

Rationale: The correct answer is A, parallelism. The sentence contains a parallelism error because the verbs in the list are not in the same grammatical form. In a parallel structure, all items in a list should be formatted consistently. In this case, 'take a Mediterranean cruise' and 'going to Pompeii' are not parallel. 'Go to Pompeii' should be corrected to 'visit Pompeii' to maintain parallelism. Choices B, C, and D are incorrect because the sentence is a complete sentence, does not have any misplaced modifiers, and does not involve subject-verb agreement errors.

4. When evaluating the credibility of research sources, which of the following is a valid consideration?

• A. It is credible if published in a peer-reviewed scholarly journal.
• B. It is never credible if it is a source published online.
• C. It is not necessarily more credible based on author affiliations.
• D. The number of times a source is cited does not affect its credibility.

Correct answer: A

Rationale: The correct answer is A. It is credible if published in a peer-reviewed scholarly journal because peer review ensures that the research has been evaluated by experts in the field for quality and accuracy before publication. This process enhances the credibility of the research source. Choice B is incorrect because not all online sources are unreliable; credibility depends on various factors beyond the publication medium. Choice C is incorrect because author affiliations can indeed impact credibility, but they are not the sole determinant. Choice D is incorrect as the frequency of citations can indicate the impact of a source but does not guarantee its credibility.

5. 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.
