Here's why:
* The context: The sentence is likely talking about a debate, discussion, or a formal setting where opposing sides present their viewpoints.
* The verb "made": This implies a deliberate action of delivering something.
* The noun "pitch": This word often refers to a persuasive speech or a set of arguments designed to convince an audience.
Therefore, "opposition made its pitch" means the opposing group presented their arguments or proposed their ideas to the audience.
