From the words or group of words lettered A to D, choose the word or group of words that best completes each of the following sentences:
I am not accustomed..........on an empty stomach

Answer Details

The correct answer is "to sleeping". The phrase "accustomed to" means being familiar with or used to something. The sentence implies that the speaker is not used to doing something on an empty stomach. Therefore, the correct form of the verb is "to" followed by the gerund or present participle form of the verb "sleep", which is "sleeping". "To sleep" is the bare infinitive form of the verb, which does not fit grammatically in this sentence. "To have slept" is the present perfect tense and does not fit the context of the sentence. "For sleeping" is a prepositional phrase that does not fit grammatically in this sentence.
