Insert _was_ or _were_ in each of the following sentences, in each case
giving a reason for your choice. Remember that the indicative _was_ is
used to denote a statement of fact in the past time, and the subjunctive
_were_ (singular and plural) is used to denote a possibility, something
that is supposed to be true, or a statement entirely contrary to fact,
as in a wish.
