Rationale: To effectively adapt your writing style to different audiences, it is essential to consider factors such as the audience's age, background, and level of knowledge. Adapting vocabulary, tone, and level of detail to match the audience's needs enhances communication and ensures better understanding. Choice A is incorrect because using the same formal tone for all audiences may not be suitable or engaging for different groups. Choice C is incorrect as relying solely on jargon and technical terms may alienate those who are not familiar with such language. Choice D is incorrect because focusing solely on your own voice and writing preferences may not effectively communicate your message to diverse audiences who may have different preferences and needs.

Correct Answer: A

Rationale: Option A correctly uses the gerund form 'playing' as the direct object of the verb 'is.' In option B, 'traveling' is used correctly as a gerund after 'enjoys.' Option C also correctly uses 'Reading' as a gerund at the beginning of the sentence. However, in option D, 'Writing' is used as a gerund, but it lacks context or a clear function for the -ing form in the sentence, unlike the other options. The gerund form should serve a purpose in the sentence structure, which is not evident in option D.

Correct Answer: D

Rationale: Ordinals (numbers with "th", "st", "nd", etc.) are generally written as words when used before nouns. Option (d) is correct.

Correct Answer: C

Rationale: The correct answer is 'C - colorful.' Adjectives are words that describe or modify nouns or pronouns. In this sentence, 'colorful' describes the noun 'sunset,' making it the adjective in the sentence. Choice A, 'sunset,' is a noun, not an adjective. Choice B, 'with,' is a preposition. Choice D, 'painted,' is a verb, not an adjective. Therefore, the correct answer is 'C - colorful.'
