Q: The Marlan Sea and The Jowal Sea are two bodies of water currently being studied by scientists at the Hamford Research Complex. The goal of the study is to find out which sea would be a better choice to support the construction of an experimental underwater laboratory. The employees first begin by analyzing the surrounding regions of the two seas. They discover that the Marlan Sea has many rivers flowing into it. The vast majority of these rivers are located near farms that grow crops to sell to the local cities. The Jowal Sea is surrounded by mostly uninhabited land. The rivers that flow into it have almost no human civilizations near them and instead are surrounded by flat plains and some forests. Which sea has more oxygen in it?
A: Jowal
