I think that the question is:
Which of the following would serve as support for this assertion? and apart from the first sentence, those are options.
and the answer is: both of the above. One sentence lists the benefits for the team and the other for the company.
Low income, less jobs, taxes,no education
The League of Nations, frankly, sucked.
Other factors included:
The US didn't join.
The Treaty of Versailles (joining the League was like a punishment)
Limited Variety of Nation in the League (many countries weren't invited to join)
And, the League was practically unable to negotiate disputes.
The amount of senators per state would be 2
I think is B
I hope this helps!:)
