CELPIP Speaking Task 5 asks you to compare two options and persuade another person to choose one. A strong answer clearly states your choice and explains why it is better.
I think we should choose the gym membership because it gives us more flexibility and better long-term value. First, a gym usually has many types of equipment, so we can do cardio, strength training, and stretching in one place. In comparison, the swimming pool is useful, but it only gives us one type of exercise. Second, the gym has longer opening hours, which means we can go before work, after work, or on weekends. That would make it easier for us to stay consistent. The swimming pool might be relaxing, but if our goal is overall fitness, the gym is the better choice. So I really think we should go with the gym membership.
