What term describes assumptions that must be accepted for an argument to be true?

The term that describes assumptions that must be accepted for an argument to be true is "underlying assumptions." These are the foundational beliefs or premises that are taken for granted within the context of an argument. Without accepting these assumptions, the argument may not hold or may lead to different conclusions. Identifying underlying assumptions is crucial in critical thinking, as it allows one to assess the validity and strength of an argument.

In contrast, logical fallacies refer to errors in reasoning that undermine the logic of an argument, but they do not specifically highlight the assumptions that are required for its truth. Inductive reasoning and deductive premises refer to methods of reasoning and structures of arguments rather than the assumptions themselves. Therefore, recognizing the underlying assumptions is key to critically evaluating the argument's overall validity.
