Take the following as truth: This eerie lake, shimmering in the heat, is so heavy with salt and other minerals that nothing lives in its waters; swimmers find it almost impossible to sink or even to submerge themselves.
Then the following statement: "They've tested the salinity of the water and it was unusually high, so high that there are no signs of life in it whatsoever." is true, false, or inconclusive?
Answer: Inconclusive
