Q: Jim and Greg are brothers who both run their own farms, but they rarely see each other due to them living in different states. Greg runs a farm in Texas where he rarely sees rain so he spends much of his day watering his crops. Jim lives in Illinois where it rains much more regularly so he has more time to spend dealing with his farm animals instead of watering his plants.

The brothers are currently planning a fishing trip together, but they are just debating which lake to travel to. Whose lake will have more algae?

Jim
