Grammar/Logic question

[quote=“TomHill”]It if rains at the weekend, it’ll be very busy.
If we go to the pool now, we won’t go to the beach.

My conclusion is that the test is poor and that both sets of answers are correct as we are teaching grammar, not logic.[/quote]
Actually, those second two sentences seem to be both grammatically correct and logical. You just have to think of a context in which it would make sense-- and in this case it isn’t even that difficult.

Sentence 1: You work in an umbrella store in a holiday spot— or any sort of situation where raining on the weekend would cause a place to become busier.
Sentence 2: A parent gives children a choice of going to the pool or the movies now and the movies or the beach tomorrow. The children want the pool today and the beach tomorrow.

I’d give those kids full marks on that question and flunk the test writer.
