<p>Space excursion have not been arranged yet ( because they would be expensive )</p>
<p>A) as it is
E) as they are requiring a lot of money</p>
<p>So guiys,what do you think ?
I put E .I know A) is more succinct ,but didnt seem grammatically correct .Have not been is a present (perfect) form ,as it is ''are requiring'' ,while ''would be'' refers to the past . Am I correct ?</p>
<p>What are the other answer choices? I believe it would be A. “Would be” is the conditional tense and refers to a possible event in the future, not a past event.</p>
<p>I assume it’s supposed to be *space excursions, in which case E is completely incorrect. Somebody else can probably explain the grammatical logic behind it, but it just isn’t something you’d say. It would have to be “as they require a lot of money” or “as they would require a lot of money”. A seems correct to me, although I suppose there might be a “better” answer choice among the others.</p>
<p>E) is wordy (a lot of money kills the whole phrase) and the gerund usage is illogical when “they require” would just suffice.</p>
<p>Would be could refer to the past if it’s a conditional phrase that references the past. (It could also reference future in the past). But I also think it could be a conditional future if the main clause is already improbable -> (space excursions are improbable).</p>
<p>Yeah, “would be” is future conditional.</p>
