Wait are oceans and seawater the same?

I was confused as to how to read this.

@Lui, thank you for your question,

In my opinion, one of the toughest calls to make on the LSAT is when the LSAT test-makers are bringing in a whole new concept, or just using a synonym for the same concept. I consider this like "the final boss" of the LSAT. Here, when they refer to the composition of the ocean (which is made up of water), and separately to seawater, then yes they are referring to the same concept. Unlike when they give premises about "Monkeys" and then a conclusion about "All Mammals," those are not synonymous.

Hope that helps and happy studying,
