Question

Given the following sets, select the statement below that is true.
A = {l, a, t, e, r}, B = {l, a, t, e}, C = {t, a, l, e}, D = {e, a, t}

B ⊂ C and C ⊆ A
C ⊆ B and D ⊂ B
D ⊂ A and A ⊂ D
B ⊂ A and C ⊂ D
D ⊆ A and A ⊂ C

Answer 1

B ⊂ C and C ⊆ A ---- false AND true ---> false
C ⊆ B and D ⊂ B
D ⊂ A and A ⊂ D ---- true AND false ---> false
B ⊂ A and C ⊂ D
D ⊆ A and A ⊂ C

try the others, remember that for
true/false AND true/false , only true AND true ---> true
any other combination is false.

Answer 2

This one is particularly confusing to me :/
