You don't need to diagram the statements out to find the correct answer here. But I have diagrammed them for you below just in case you were curious:

"People are not happy unless they feel that they are needed by others."

So: if people are happy, then they feel that they are needed by others.

P1: PH ==> FNBO
not FNBO ==> not PH

"Most people in modern society can achieve a feeling of indispensability only within the sphere of family and friendship."

Q1: PMS-most-FIOFF

"almost everyone knows that his or her job could be done by any one of thousands of others."

So: Most people know that his or her job could be done by any one of thousands of others

Q2: PK-most-JDA
JDA-some-PK


Now, we are told that a required condition, i.e. the necessary condition, for people being happy is that they feel needed by others. We also know that the majority of people only feel indispensable, i.e. only feel needed, within the sphere of family and friendship. Remember that a majority, i.e. most, means more than 50%, but less than 100%. So, this means that at least one person does feel indispensable outside of the sphere of family and friendship, i.e. answer choice (E): "Fewer than a majority (some) of people in modern society can find happiness outside the sphere of private interpersonal relationships."

Hope that helps! Please let us know if you have any other questions.

If you were not to diagram this question, how would you arrive at answer choice E?

I'm also wondering the sam thing. How would you arrive at E without diagramming?

I don't see how diagramming the 2nd and 3rd conditionals here would be helpful given that at least in their diagrams shown here, they don't tie together. Wouldn't this be a time waster?
