I was solving a question which is the following :(adsbygoogle = window.adsbygoogle || []).push({});

Give examples of 3 sets W,X,Y such that W ε X and X ε Y but W doesn't ε Y . I solved the question by taking the following 3 sets:

W = {1,2}

X = { 7 , 8 , W}

Y = { 3 , 4 , X}

looking it from the theory point of you I find that W is not a part of Y but the problem is I cannot come up with an example from real life that satisfies this condition. Kindly help me visualize this.

Thanks in advance.
