sentences 10 and 11
Explanation:
It's not A because they're comparing fresh water and salt water.
It's not B because they're trying to also find out their freezing rate comparative.
It's not D because they're trying to compare the freezing rates and they need them at the same temperature. Also said in sentence eight that they do that anyways.
It's easy to see that sentences 10 and 11 contains the conclusion if you just read the two.
So, if 1 mole occupies 22.4 L, the imediate conclusion is that a bigger number of moles will occupy more than 22.4 L, and a smaller number of moles will occupy less than 22.4 L. In your case, 3 moles of gas will occupy 3 times more volume than 1 mole of gas
