Question

The Prohibition Party was founded in 1869 solely for the purpose of preventing the manufacturing and sale of alcoholic beverages in the United States. The Prohibition Party is an example of which of the following?
A. a party that has a broad program and attempts to gain national favor
B. a group that broke away from a major political party
C. a party that has only one goal

Answer 1

C) a party that has only one goal

why: its literally in the question, "solely" means only and its one goal was to prevent the manufacturing and sale of alcohol in the US

Answer 2

I believe the answer is: a party that has only one goal.

This type of party tend to be formed and funded by one specific interest group that wanted to influence a single legislation from the government. One-goal party would most likely unable to obtain majority votes since only a handful of people influenced by the cause promoted by the party.
