Answer #1

As questions itself stating that sam wants to predict who will be representative of grade seventh students council representative, therefore we can only consider grade seventh students. Suppose there may be 100 students in grade seventh, hence from that 100 student we have to choose one representative. We are not going to consider entire school here. Hence only grade seventh will participate in this survey to choose grade seventh representative council.

Note- please find me in comment box if you find any difficulty.
