Venn diagram of Or and And in LR

[hyk1310]

Is it safe to conclude that Or encompasses more than And, in the sense that And is included in Or?

For example, in PT 25 S4 Q14, the stimulus says "...books will almost certainly contribute to the intellectual and emotional enrichment..."

Answer D says "blah blah blah... either intellectually or emotionally"

Here, I took the or to be inclusive of the "And", especially since we're not told that the two are mutually exclusive.

Please do let me know if I am making the right logical thinking for this principle question!

If you want to talk about that specific question, please post it in that part of the forum.

Yes, you're right that since "or" means "at least one", it is the broader term.

If you were making a venn diagram of truth value (sounds fun!), X and Y are a subset of X or Y.
