Final answer:
The statement that a wide variety of competing groups represent nearly every interest in the state supports the pluralist system in Texas, where political power is dispersed among numerous organized groups.
Step-by-step explanation:
The statement that supports the argument that Texas operates under a pluralist system is "a wide variety of competing groups represent nearly every interest in the state." This aligns with pluralist theory, which suggests that political power is spread amongst a variety of organized groups, each vying for attention and influence on policy makers. In a pluralist system, groups like PACs, professional groups, and political parties work to have their voices heard and affect governmental decisions. This competition is thought to be beneficial for democracy, as it prevents a single interest from dominating and ensures a range of interests are considered.
