Step-by-step explanation:
The ironic aspect of Jordan's statement about comparing large and small parties is that C) Jordan's statement suggests that small parties are less influential than large ones.
The passage states that in a truly multiparty system, having a large number of political parties would lead to a crowded and fragmented political field, making it difficult to arrive at decisions that benefit the public interest. This is referred to as hyperpluralism, and it contrasts Jordan's statement that highlights the advantages of both large and small parties.
Furthermore, the passage mentions that political parties representing the interests of minorities, ideological issues, or other specific issues would compete for attention. This implies that small parties would also have a potential for influence, contradicting Jordan's statement.
