Question 69579
This is a classic "If ... then" relationship where the "if" identifies the hypothesis (something supposed to be true for the sake of argument) and the "then" identifies the conclusion (the conclusion is the outcome of the hypothesis).

Therefore, "if you get all a's on your geometry tests" is a hypothesis (something we suppose to be true)

and

"then everyone will want to sit near you in class" is the conclusion (outcome that will happen if the hypothesis is true).

Notice that the hypothesis may never happen, but if it does, the conclusion could be wrong.

For example, you may get all a's but maybe people don't like you ... or maybe they don't want the temptation of copying from you, so they may not want to sit by you anyway.
