Question

what did the author mean when he said, \the cause of america\ is \the cause of all mankind\?
○ nobody wants to pay taxes on tea, paper, and lead.
○ people in all parts of the world wanted to unite.
○ everybody wants to be able to decide how to get rich.
○ people everywhere struggle against oppressive government.

Explanation:

The phrase "The cause of America" being "the cause of all mankind" implies a universal struggle. Oppressive government is a global issue. Taxation (tea, paper, lead) is too specific. Uniting (option 2) is not the core. Deciding to get rich (option 3) is material - focused. Struggling against oppressive government is a common human struggle.

Answer:

People everywhere struggle against oppressive government.
