In the following sentence, which part of speech does the word 'capacity' function as?

Correct Answer: B

Rationale: In the sentence, 'capacity' is used to refer to the maximum amount that something can contain or produce, making it a noun. It is not functioning as a verb (choice A), as it is not describing an action. It is not an adverb (choice C) because it is not modifying a verb, adjective, or another adverb. Additionally, it is not a pronoun (choice D) because it is not replacing a noun or noun phrase. Therefore, the correct answer is 'B: Noun.'

Correct Answer: A

Rationale: The correct transitional words or phrases that indicate contrast are 'Regardless' and 'On the other hand.' 'Regardless' introduces a contrasting idea, while 'On the other hand' explicitly signals a shift in perspective or introduces an opposing viewpoint. 'Furthermore' and 'Moreover' are not used to indicate contrast; instead, they are used to add more information or support to a related point.

Correct Answer: C

Rationale: The correct plural form of 'syllabus' is 'syllabi.' In English, when a word ends in -us, the plural form is often changed to -i. Therefore, 'Syllabi' is the correct plural form. Choice A, 'Syllabus,' is the singular form, not the plural. Choice B, 'Syllaba,' does not follow the standard pluralization rule for words ending in -us. Choice D, 'Syllabis,' is an incorrect plural form that does not follow the standard English pluralization rules.

Correct Answer: C

Rationale: Relative pronouns are acceptable in a research paper for connecting clauses. Colloquialisms (choice A) are informal expressions that are not suitable for academic writing. Contractions (choice B) are considered too casual for a research paper. The second-person point of view (choice D) should be avoided in research papers as it can make the writing less objective and scholarly.
