The “liberty boys” were established as a protest against which of these

The Liberty Boys, then named Sons of Liberty, were established as a protest against the Stamp Act.

Explanation:

The Stamp Act was adopted by Parliament and promulgated by the king on March 22, 1765, but did not come into effect until November 1, 1765. It required the payment of a stamp for all publications made in the colonies. It aroused great animosity on the part of the American colonists and was hardly applied. Tax collectors were indeed threatened with tar and feathering by the most radical settlers. Many settlers refused to pay for the stamps and the situation became more radical. In Boston, the home of Massachusetts Governor Thomas Hutchinson was vandalized. Many associations were born to organize the protest: they would soon be known as the Sons of Liberty. Similar incidents occurred in New York and Charleston. The stamps were seized and destroyed. Committees of Correspondence were formed to unite opponents and relay calls for the boycott of English goods.  

Egoism

Explanation:

Egoism refers to a moral theory which claims that acting according to one's self-interest is the ideal route to be morally good. Egoists also assume that if everyone behaves in their own self-interest then the social system is more effective to fix moral dilemmas to all parties' satisfaction. It's based on the premise that individuals are usually the best judges of what's in their own interest, and they're far more driven to work hard to support themselves than to accomplish some other goal.
