Correct Answer: B

Rationale: The expression 'think outside the box' promotes creativity and innovation by urging individuals to consider unconventional and original ideas to solve problems or tasks, rather than sticking to conventional or traditional methods. This phrase emphasizes the importance of exploring new perspectives and solutions that are not limited by existing boundaries or norms. Choice A is incorrect because 'think outside the box' encourages individuals to break away from established procedures. Choice C is incorrect as the phrase contradicts accepting traditional ideas. Choice D is incorrect because 'think outside the box' does not focus on avoiding mistakes but rather on exploring new and innovative solutions.

Correct Answer: D

Rationale: The correct answer is 'D, Past perfect tense.' In the sentence provided, the verb 'had left' is in the past perfect tense. The past perfect tense is used to indicate an action that was completed before another past action, which in this case is 'arrived.' Therefore, the main verb tense in the sentence is past perfect. Choices A, B, and C are incorrect because the sentence does not contain present, past, or future tense verbs as the main verb. Instead, the main verb 'left' is in the past perfect tense, showing an action completed before another past event.

Correct Answer: B

Rationale: The correct answer is 'B: 'that won the award.' A relative clause provides additional information about a noun in the sentence. In this case, 'that won the award' is the relative clause specifying which book out of all books is being referred to. It is essential to recognize and understand relative clauses for better comprehension of sentence structures. Choice A ('The book') is the main noun phrase and not a relative clause. Choice C ('was a bestseller') is the main clause of the sentence, not a relative clause. Choice D ('award') is a noun but not a relative clause as it does not provide additional information about a noun in the sentence.

Correct Answer: C

Rationale: A noun is a word that names a person, place, thing, or idea. In the given sentence, 'aroma' is the noun as it names a specific thing, in this case, a smell. 'Filled' is a verb showing an action, 'kitchen' is a place, and 'freshly' is an adverb modifying the adjective 'baked.' Therefore, 'aroma' is the correct choice as the noun in this sentence.
