> What Everyone Knows

I don't believe everyone knows of the formal meaning in logic, even among candidates for a Master's program. He doesn't seem to want to consider that there's a flaw in his question, rather than a failure on our academic institutions.

> and What No One Knows

The question certainly has some flaws in phrasing (discussed elsewhere in this thread). Its use of the word "implies" is not a flaw. If intro-level formal logic is a valid requirement, then there is no problem using "implies" in that context. If intro-level formal logic is not a valid requirement, then the whole question is bunk, but not the use of "implies".

It's perhaps plausible that someone might assume the colloquial definition, but if a candidate for a master's program doesn't know of the formal logic definition in the first place, that is a failure of our academic institutions.
