Well, actually the idea is that because it is wrongly spelt it should be discarded, and the correct answer would be "what". I didn't realise "when" was another possibility. I will change that, thanks for telling me.
The whole test is three pages, but I divided it into three separate worksheets so that they didn't have to do it all in one go.
Hi, there! I thought number 8 (first exercise) was a bit of a trap and I should choose "when" because "which" is spelled wrong ("witch"), but after I checked my answers I realised it was a typo. Thought I'd let you know, it's a great worksheet in every other aspect :)
