Correct Answer: C

Rationale: The correct spelling is 'embarrassing.' It is spelled with two consecutive r's and two consecutive s's. Option C is the only choice with the correct spelling. Options A, B, and D all have incorrect spellings. 'Embarrasing' (Option B) is missing an 'r,' and 'Emberassing' (Option D) has an extra 'e' and a missing 'r' and 's.' Therefore, the correct answer is Option C.

Correct Answer: B

Rationale: The correct answer is 'B - resting' because it is the present participle form of the verb 'rest' and fits appropriately in the sentence structure 'After resting for an entire afternoon, the resident felt revitalized.' The present participle is used to show an ongoing action that happened before the feeling of revitalization. Choice A 'having rest' is incorrect as it does not convey the continuous action needed in this context. Choice C 'rested' is incorrect as it is the past tense form and does not match the tense of the sentence. Choice D 'rest' is incorrect as it is the base form of the verb and does not provide the needed -ing form for the sentence.

Correct Answer: A

Rationale: The word 'oneself' is a reflexive pronoun that refers back to the subject of the sentence, allowing the sentence to be grammatically correct. Options B and C, 'oneselves' and 'hisself,' are not standard English words. Option D, 'themselves,' is a plural pronoun and does not agree with the singular noun 'one' in the sentence.

Correct Answer: A

Rationale: The word 'iterate' is not spelled correctly in the sentence. The correct word that should be used here is 'itinerant,' which means constantly traveling from place to place, especially for work. In this context, 'iterate' does not fit as it means to repeat a process or utterance. 'Continually' is spelled correctly and means happening without interruption. 'Within' and 'district' are also spelled correctly and are used appropriately in the sentence. Therefore, choice A is the correct answer.

Correct Answer: A

Rationale: The correct punctuation needed in the sentence is a period. A period is used to indicate the end of a sentence. In this case, the sentence 'After you complete your rounds, please check in at the station.' is a complete thought and requires a period at the end to show that it is a complete sentence. The other choices are incorrect because a comma would not be suitable at the end of a sentence, a colon is used to introduce a list or an explanation, and a semicolon is used to connect two closely related independent clauses.
