Given a premise, retrieve a hypothesis that is entailed by the premise.but uh i i have one mainly i bought it because i'm in uh taking a lot of courses along with work and  it's very useful in that respect but i hope to do something more with it
I purchased one, largely due to the fact that I am doing numerous courses, for which it is very helpful.
I didn't buy it in the end because I knew it wouldn't prove to be very useful.
