past perfect or past simple
There are two sentences and I have to choose one that is correct:
a)I felt ill when I ate the pudding.
b)I felt ill when I had eaten the pudding.
I am really confused here, as the rules of both past perfect and past simple can indicate the sequence of actions, and one of the rules for past perfect is to describe reason for past situation.
So, I am not really sure what is a really correct answer here.
A or B must be chosen based on a picture which represents a guy eating a pudding.
If you could help me that would be great, thank you :)
