Multi-party initiatives are becoming increasingly popular among the members of the parliament of Country W. Although legislation proposed under the auspices of more than one party may not adhere as strictly to the agenda of each of the parties involved as legislation proposed by only one party, the political backing of the voting blocs represented by the cooperating parties make such proposals more likely to pass than proposals that come from a single faction alone. The benefit of multi-party initiatives is that legislation important to the general welfare of Country W that might otherwise have foundered in inter-party disagreements can effectively be enacted.

A) Multi-party initiatives deal with proposals too large and complex for a single party to have passed into law.
B) Multi-party initiatives produce a confluence of ideas that results in legislation that is generally better overall for the welfare of Country W.
C) Multi-party initiatives have in the past been less common in the government of Country W than now.
D) Jointly-supported proposals represent only the interests of the parties that back their passage into law.
E) Jointly-supported proposals are not any more likely to be passed into law than proposals presented by individual parties
