I inadvertently missed out the most impossible* one of all.
5. At this time tomorrow __________ the museum.
a) we're going to visit
b) well be visiting
c) we'll visit
d) we're to visit
If you can pick between those four answers your better at this language lark than I am.
(* And yes, I know "impossible" is supposed to be one of those adjectives that you can't put "more" or "most" in front of. I don't buy it. Never have. It's just more bad advice.)
