Question

1776 saw what major setbacks for patriots of the american revolution?
benedict arnold betrayed america to the british.
new york and philadelphia were lost to the british.
britain drove the american militias from bunker hill.

Explanation:

• Benedict Arnold's betrayal occurred later in the war, not in 1776.
• The Battle of Bunker Hill took place in 1775.
• In 1776, the British did gain control of New York. Philadelphia was captured by the British in 1777. But among the options given, the most relevant for 1776 is the loss related to New York (as the other two options have incorrect time - lines for 1776).

Answer:

New York and Philadelphia were lost to the British.
