The situation is that I am going to organize an activity to raise money to help poor students. There are three options to choose: a school concert, a second-hand market, and a marathon.

Among the three options, I think a school concert is the best choice because it’s interesting and can attract many students. For example, students love music and will join the event. The second reason is that it’s easy to organize with help from teachers and students.

I don’t think a second-hand market is suitable because it takes a lot of time to prepare and find items to sell. For instance, not many students have things to donate.

Although a marathon is a meaningful idea, I don’t choose it because it requires much space and safety management. To illustrate, we would need permission and medical support.

To sum up, if I were in the case, I would choose a school concert for the reasons I have mentioned.
