Question

We could phone Jill later, ___________ we have to hurry up.

Answer 1

We could phone Jill later, seeing that we have to hurry up.

The meaning of this sentence is: we are in a hurry so we have no time to phone Jill. 'We have no time' is the reason why we cannot phone Jill. To give a reason for a certain situation we use 'seeing that, seeing as, as, because, since' + clause. Other given linking words do not relate to the meaning of the sentence.
