I am crushing these PAI disagree questions !

This seems so simple to me, yet the MSS questions were getting me!!

If you are a shark then you are a fish. Ollie is a shark. Ollie must be a fish.

S - F

O(f)

A-B

x(b)

Am I right?

If one is a shark then one is a fish. Ollie is a shark which means ollie has to be a fish.

mini subset/dot: ollie

subset: shark

superset: fish

Sharks are sufficient to fish, but not necessary. Fish is necessary to be sharks.

Am I right?

Subset: teacher

Superset: career

A teacher is sufficient for a career, but not necessary.

A career is necessary for a teacher.

Taking my example from the last lesson (lmk if I got it wrong) -

Subset: pizza

Superset: food

Pizza is sufficient to be food, but food is not necessary to be pizza.

Going back to do my foundation lessons because I am the worst studier and skipped ahead to LR lol

I think I get it - subset is small and the super set is big

subset: pizza

superset: food

Needed this! Currently improving in some areas and struggling in other areas of LR. It really is discouraging when improvement is not happening when you put so much work into the test!
