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: D

Rationale: Choice D is the most appropriate sentence in terms of style, clarity, and punctuation. It maintains parallel structure in the sentence by using 'Although Lucinda was concerned about the possible side effects, she continued to take the medication that her doctor had prescribed for her.' This choice effectively conveys the cause and effect relationship between Lucinda's concern about side effects and her decision to continue taking the medication. Choices A, B, and C have issues with subject-verb agreement, awkward phrasing, or lack of clarity in expressing the relationship between Lucinda's concern and her action, making them less correct compared to Choice D.

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.

Correct Answer: A

Rationale: The correct answer is A: 'A doctrine.' The suffix -ism is commonly used to denote a system, doctrine, or belief. Words like polytheism, communism, and nationalism all represent specific doctrines or systems of belief. Therefore, the suffix -ism in these contexts indicates a particular set of ideas or principles. Choices B, C, and D are incorrect because -ism does not typically refer to a condition, characteristic, or state of being, but rather to a specific ideology, doctrine, or belief system.

Correct Answer: B

Rationale: The correct answer is B. Titles used before names, like 'Uncle' in 'Uncle Archibald,' should be capitalized. In choices A, C, and D, 'cousin,' 'mother,' and 'sister' are common nouns and should not be capitalized unless used before the name as part of the title. Therefore, they are incorrect choices. Choice B demonstrates proper capitalization rules by capitalizing 'Uncle Archibald,' making it the correct option.
