Diagram

Can someone please diagram the statement, "no one gains such understanding without experience." I get confused on these more complex statements.

Hello @masonnavarrete,

We are used to the if/then format when discussing sufficient and necessary conditions, so sometimes it helps to frame statements in terms of if/then.

"Problems can be solved only by people who really understand them, and no one gains such understanding without experience."

If someone solved a problem (SP), then what? That person really understood (U) it. No exceptions, because people with understanding are the only ones who can solve problems.
SP - - - - - - - - > U

If that person had the understanding (U), then what? That person had experience (E). No exceptions, because no one gains understanding without experience.
U - - - - - - - - - -> E

Combining these statements: SP - - - - - - >U - - - - - - ->E
Understanding and experience are both necessary for solving problems, which is why C is correct.

It is very important that you practice identifying sufficient and necessary conditions when they are not explicitly written in the if/then format. In this case, "only" and "no one" were key words.

The word "always" in answer choice C made me think that it was too strong of a word for a must be true question? Please explain
