B) The Green Party's electoral success will be hindered as its unique platform is absorbed.
C) The Democratic Party will be forced to share campaign funds with the Green Party.
D) The Green Party will successfully replace the Democratic Party as a major party.
Correct Answer: B
This scenario is a direct application of the principle that the incorporation of a third party's agenda into a major party's platform serves as a barrier, diminishing the third party's appeal to voters who can now find those policies within a major party.
A) A third-party candidate is unable to raise as much money as major party candidates.
B) In a congressional election, a third-party candidate receives 20% of the vote but wins no seat.
C) A third-party candidate is not invited to a nationally televised presidential debate.
D) A major news network provides minimal coverage of a third party's national convention.
Correct Answer: B
This scenario directly illustrates the effect of a winner-take-all system. Despite securing a significant minority of votes (20%), the candidate wins nothing because they did not come in first place, highlighting how this system is a barrier.
A) Third parties are primarily hindered by a lack of compelling ideas and charismatic candidates.
B) The primary obstacles are financial, as third parties cannot compete with the fundraising of major parties.
C) Third parties struggle against both the fundamental rules of the electoral system and the strategic adaptability of the major parties.
D) Voter apathy and low turnout are the most significant barriers to the success of third parties.
Correct Answer: C
This option correctly combines the two distinct barriers mentioned in the text: the 'rules of the electoral system' (winner-take-all) and the 'strategic adaptability of the major parties' (incorporating third-party agendas).
A) violates copyright law and leads to lawsuits.
B) confuses voters, leading to lower overall turnout.
C) forces the third party to find more radical and less popular issues.
D) removes a key reason for voters to support the third-party candidate.
Correct Answer: D
The core function of this barrier is that if voters can get the policies they want from a major party candidate who has a realistic chance of winning, their incentive to vote for the third-party candidate, who is a long shot, is greatly diminished.
