there's this kind of question in RC asking you to add a sentence at the end of the passage.
for this type of question, I guess it's still like a main point/must be true question. that is it sums up the passage, but still stays in the scope without any extention.
is there an RC question asking you to choose a sentence to begin the next paragraph after the end of orginial passage?
if there is, I guess the strategy would be different from the first one, but I haven't met any to test my thoughts.
