Correct Answer: C

Rationale: Option C uses formal language by employing more sophisticated vocabulary ('cinematic experience') and refraining from informal terms like 'awesome' and 'flick.' Choice A ('awesome') and Choice D ('flick') use informal language typically used in casual contexts, making them less formal. Choice B, while more formal than Choices A and D, is still less formal than Choice C due to its less sophisticated vocabulary and directness in expressing dissatisfaction compared to the refined language used in Choice C.

Correct Answer: B

Rationale: Option B is the correct answer as it uses the gerund (-ing) form for all three hobbies, achieving parallel structure. Parallel structure requires that elements in a sentence are grammatically balanced. In this case, all three activities are presented in the same form, making the sentence clear and consistent. Choices A, C, and D do not exhibit parallel structure as they mix verb forms or use infinitives, breaking the parallelism needed for correct grammar.

Correct Answer: D

Rationale: A compound-complex sentence consists of at least two independent clauses and at least one dependent clause. In option D, 'He enjoyed reading the book' is an independent clause, while 'because it was suspenseful' is a dependent clause, making it a compound-complex sentence. Choices A, B, and C do not meet the criteria for a compound-complex sentence as they either lack the required combination of independent and dependent clauses or do not contain multiple independent clauses.

Correct Answer: B

Rationale: The correct answer is B: 'To bite off more than one can chew' means to take on more than one can handle or to undertake a task exceeding one's capabilities. This idiom warns against overcommitting oneself and facing difficulties in managing the workload effectively. Choice A, 'To be overly confident,' is incorrect as the idiom implies a situation of overestimating one's capacity rather than confidence. Choice C, 'To be easily discouraged,' is not related to the idiom's meaning, which focuses on task difficulty rather than emotional response. Choice D, 'To be meticulous in planning,' is not accurate as the idiom refers to the execution of tasks rather than the planning phase.

Correct Answer: B

Rationale: In the sentence, 'beautiful' is used as an adjective to describe the flowers. To transform the adjective 'beautiful' into an adverb, you add '-ly,' resulting in 'beautifully.' Adverbs modify verbs, adjectives, or other adverbs, offering more details on how an action is performed. Choice A ('beautiful') is the original adjective form and not the adverb form. Choice C ('beautification') is a noun, not an adverb. Choice D ('beautify') is a verb, not an adverb.
