PSAs and SAs

What is the difference, can someone please enlighten me.

A sufficient assumption, if added as a premise to the argument is going to make the conclusion 100% true.

Pseudo Sufficient Assumption questions aren't asking you for a sufficient assumption, but they're asking you for something that will most justify the conclusion—so it doesn't have to make the conclusion 100% true, but usually comes really, really close to it (hence the word pseudo).

I like to think of PSAs kind of like really strong strengthen questions. The correct answer choice will make the conclusion very well supported, if not 100% supported, but it doesn't have to.

You can see the difference in validity that these questions are testing you on with this video in the core curriculum:

Hope this helps!
