I came across two questions concerning conditionals in a coursebook. It goes like this,
Most people (buy/will buy) state-of-the-art products if they (have/will have) the money.
The right answer is using the first conditional structure i.e. will buy and have.
My question is why not buy and have instead! Couldn't it be a general truth? How should I pick between these two? Is there a quick trick to help us choose the correct answer?
There is an incomplete sentence in which the students are instructed to finish it using a result clause:
If people are not careful when they choose new products, ...
My question is if I could use both zero and first conditional structures in here and both would be correct
If people are not careful when they choose new products, they regret/will regret it.
