What are ways that scientists have proposed to deal with the problem?

Well, scientists make a hypothesis. You see, a hypothesis is a way scientists test or try to make sure the problem or statement is true. For example, putting 4 plants outside and labeling them from 1 A-D. Then, watering A every day. Watering B only twice a week. Watering C only four times a month. This hypothesis is showing the scientist trying to find out how many times he or she should water the plant. Hope this helped!! :)
