Question 198096
The two circles are named P and Q. 
P = {A D B E}
Q = {B E C F G}}}

a) asks for the intersection of P and Q. That means 'what members are in BOTH P and Q. B and E are in both, so the answer is {B E}
b) asks for the union of P and Q. That means 'what members are in either P or Q'
P has A D B E and Q has B E C F G.
So P union Q = {A D B E C F G}
