Which sentence uses the phrase 'by the way' correctly?

Correct Answer: C

Rationale: Option C correctly uses the phrase 'by the way' to introduce additional information that is not directly related to the previous sentence, making it a natural and appropriate use of the phrase in casual conversation. Choices A, B, and D do not use 'by the way' in the same context as option C. Choice A incorrectly uses 'by the way' to convey winning the lottery, which is not a casual or incidental piece of information. Choice B incorrectly uses 'by the way' after a semicolon in a way that disrupts the flow of the sentence. Choice D correctly uses 'by the way' but the information provided about the movie starting time is not a casual or incidental addition, unlike in option C.

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: C

Rationale: The sentence 'Wow, what a beautiful sunset!' expresses strong emotion ('Wow') and conveys an exclamation, indicating that it is an exclamatory sentence. Exclamatory sentences are used to show strong feelings or emotions and typically end with an exclamation mark. Choice A, 'Interrogative sentence,' is incorrect because interrogative sentences ask questions, which this sentence does not. Choice B, 'Declarative sentence,' is incorrect because declarative sentences make statements or convey information, which is not the case here. Choice D, 'Imperative sentence,' is incorrect because imperative sentences give commands or instructions, which are not present in the given sentence.

Correct Answer: B

Rationale: The correct spelling of the past participle of the verb 'lie' (to recline) is 'lain.' 'Lied' is the past tense form of the verb, not the past participle. 'Lay' is the simple past form. 'Lying' is the present participle form. Therefore, the correct answer is 'lain,' representing the past participle form of the verb 'lie.'

Correct Answer: C

Rationale: Option (C) incorrectly combines two independent clauses with only a comma, resulting in a comma splice. A comma should not be used to connect independent clauses; instead, a semicolon, conjunction, or period is needed to properly separate the ideas in the sentence. Choices (A), (B), and (D) do not contain comma splices and present their ideas in a grammatically correct manner.
