But two in five people have an acute sensitivity to cucurbitacins, which makes it understandable if they think the rest of us are crazy for eating cucumbers at all.
What does the underlined 'it' refer to?
Is it 'if they think the rest of us are crazy for eating cucumbers at all'?
Can, then, a pronoun refer to an adverbial clause?
Thank you so much.
It's a dummy "it". The meaning of that part is: that fact that they think the rest of us are crazy for eating cucumbers at all (if that is the case) is understandable
