We'll have to postpone the meeting ______ new information.

• A. After
• B. Until
• C. Because
• D. Since

Answer: (B)

Choosing the right time link shows how long the postponement will last. The idea is that the meeting should stay on hold up to the moment new information becomes available. That sense of a deadline is what “until” conveys best here. It ties the postponement to a future point in time—the moment we have the information. The other options don’t express this timing: “after” would push the postponement to begin or occur following the information, while “because” and “since” give reasons rather than a time frame. In natural English, you’d usually add a clause after the noun phrase, like “until we have new information” or “until there is new information.”
