Correct Answer: B

Rationale: The sentence starts with 'Before I had finished supper,' indicating that the action of James texting you on your cell phone had occurred before the completion of another past action (finishing supper). The past perfect tense 'had texted' is used to express an action that happened before another action in the past, making the sentence grammatically correct. Choice A is incorrect because it uses the present continuous tense, which is not suitable for indicating an action that occurred before finishing supper. Choice C is incorrect as it uses the simple present tense, which does not convey the sequence of events correctly. Choice D is incorrect as it presents the present continuous tense, which is not appropriate for the context of the sentence.

Correct Answer: B

Rationale: The correct preposition to use in this sentence to indicate the position of the fountain in relation to the driveway and the main entrance is 'between.' 'Between' conveys that the fountain is positioned centrally or in the middle of the driveway and the main entrance, making it the most suitable phrase to complete the sentence correctly. The other options do not accurately describe the fountain's position between two distinct locations, making them grammatically incorrect choices for this sentence.

Correct Answer: C

Rationale: The word 'therapist' in the sentence is used correctly. However, the word 'councilor' is misspelled and should be 'counselor' to refer to a mental health professional providing therapy services. The correct term should have an 's' after 'counselor,' making it 'counselor' instead of 'councilor.' Therefore, the word 'councilor' is the one not used correctly in the sentence.

Correct Answer: C

Rationale: The word 'boys'' should be spelled as 'boys' in this context. The correct possessive form of the plural noun 'boys' does not require an apostrophe before the final S, which indicates possession. In this sentence, the intent is to show that the pranks belong to the four boys collectively, so the correct possessive form is 'boys' without the additional apostrophe.

Correct Answer: A

Rationale: The word 'stealthy' is used incorrectly in the sentence. The correct adverb form of the word should be 'stealthily' to modify the verb 'moving.' Therefore, it should be 'Moving stealthily, the sneaky little boy reached for the cookie jar on the topmost shelf.' Choices B, C, and D are all used appropriately in the sentence. 'Sneaky' describes the boy, 'reached' is the action verb, and 'topmost' correctly describes the location of the cookie jar.
