Question

The leader of the majority party in the House of Commons becomes the

a. prime minister.
c. president.
b. dictator.
d. shah.

Answer 1

I assume that the question is about the United Kingdom Parliament - since the United States does not have a "House of Commons".

However, the United Kingdom does not have a Dictator, a Shah (Iran had a shah) or a president (since it has a monarch) - so the correct answer is "prime minister" - answer c.
