What questions are scientists asking about Lake Vostok and what are they doing to learn about the lake? ​

This is the real

Scientist were asking questions about Lake Vostok, like "How did the lake form? Does anything live in the lake? If so, what lives in the lake? How could living things survive in this environment?"

Out of curiosity, they sent russian scientists plumbing the frozen Antarctic in search of a lake buried in ice for tens of millions of years have failed to respond to increasingly anxious U.S. colleagues -- and as the days creep by, the fate of the team remains unknown.

Explanation:

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
