Respuesta :
Restrictions for who can receive government campaign money have made a contribution to the continuation of presence of a two-party system.
Option A
Explanation:
The right answer is B, although the diagram best illustrates relationship of cause and effect that has shaped American politics.
The restrictions on who is eligible for public campaign money have actually helped the two-party system to survive.
There's quite limited public financing for election campaigns in the U.S. so candidates ending up in the private sector.
In turn, it finances only those who are genuinely liable to get the positions in the vote. This closes the Democratic-Republican question and strengthens the system of two parties.
