Explanation: The question tests the understanding of conditional sentences in the passive voice and the appropriate use of tense. The sentence describes a condition where orders are being received at a certain pace, and if this condition is maintained, the company will meet its sales goal one month early.
In English grammar, conditional sentences are used to express a condition and its result. The sentence in question is a type of conditional sentence that describes a present condition leading to a future outcome. The correct construction for this type of sentence is the present simple tense in the "if" clause and the future simple tense in the main clause.
The sentence requires a passive construction because the focus is on the orders being received by the company, not on who is receiving them. The passive voice is formed using the auxiliary verb "be" and the past participle of the main verb. In this case, the correct form is "are received," which is the passive voice of the present simple tense.
Option A, "Will be receiving," is incorrect because it uses the future continuous tense in the active voice, which does not fit the context of the sentence. The future continuous tense is used to describe an action that will be in progress at a specific time in the future, which is not the case here.
Option B, "Will receive," is incorrect because it uses the future simple tense in the active voice, which does not fit the context of the sentence. The future simple tense is used to describe a future action that will happen, but the sentence requires a passive construction to describe the orders being received.
Option C, "Are received," is the correct answer because it uses the present simple tense in the passive voice, which fits the context of the sentence. The present simple tense is used to describe a present condition that, if maintained, will lead to a future outcome.
Option D, "Receive," is incorrect because it uses the present simple tense in the active voice, which does not fit the context of the sentence. The sentence requires a passive construction to describe the orders being received by the company.
In summary, the correct answer is "Are received" because it uses the passive voice and the present simple tense, which fits the context of the sentence and describes a condition that, if maintained, will lead to a future outcome.
