Q.1
Correct option: A. Despite
Explanation: “Despite” is a preposition meaning “in spite of” and is followed by a noun phrase (“their best efforts”). “Though” and “However” require a clause or act as adverbs, making them incorrect here.
Q.2
Correct option: A. Though
Explanation: “Though” introduces a contrast between having a bad teacher and passing the test. “However” is an adverb and cannot connect clauses, while “Despite” requires a noun phrase (e.g., “Despite her bad teacher”).
Q.3
Correct option: B. both, and
Explanation: “Both…and” pairs two positive qualities (“intelligent” and “hard working”). “Neither…nor” would negate both, which contradicts the sentence’s intent.
Q.4
Correct option: C. yet
Explanation: “Yet” contrasts working hard with struggling financially. “And” would imply a neutral connection, and “so” would incorrectly indicate a result.
Q.5
Correct option: B. so
Explanation: “So” shows the result of being deserving (getting the job). “And” would imply a neutral addition, and “so that” indicates purpose, which is irrelevant here.
Q.6
Correct option: B. for
Explanation: “For” (formal) explains the reason for winning (“they are well trained”). “And” would imply a neutral addition, and “so” would incorrectly indicate a result.
Q.7
Correct option: A. so…that…
Explanation: “So…that…” shows the degree of fright (“so frightened”) and its result (“could not move”). “Such…that…” would require a noun (e.g., “such fear”), and “both…and” is irrelevant.
