Hi, I am reading these papers, and I don't know what the instructions are at the beginning of the paper. Is it "choose 4 out of the first 7 questions" or is it "choose 4 out of the first 7 and make sure you choose 1 from each part" and there are parts 1 and 2? which one is it?

if it is the second one, can you please specify which questions are from part 1 and which ones from part 2
