Can we deliver on Thursday might ask whether transport is available or whether Thursday suits the recipient. A yes to one question can be mistaken for agreement on the other.
Ask the information question first when the decision depends on it. Then make the proposal explicitly. For example, confirm availability before asking the group to choose that date.
Label the remaining uncertainty
If the information is provisional, say so. Avoid presenting a possible option as a confirmed arrangement. Check who needs to agree before making a booking or another commitment.
Once the decision is made, record it separately from the questions that led there. This is particularly useful in long message threads where several possibilities remain visible. You can state that Thursday is now confirmed and identify the next action. Clear separation gives people a better chance to answer the question you intended and prevents an exploratory reply from becoming an accidental commitment.
