Selecting an Appropriate Step-Level Verifier
For which system (A or B) would a symbolic engine be the most effective type of step-level verifier, and for which system would a model that predicts the future utility of a path be more appropriate? Justify your choices based on the characteristics of each task.

Selecting an Appropriate Step-Level Verifier
Match each description of a method for evaluating an individual reasoning step with the corresponding verifier type.
A system is designed to solve complex mathematical proofs, generating one logical step at a time. The validity of each new step depends entirely on whether it follows from the previous steps according to the strict, formal rules of logic and algebra. Which of the following verifier types would be the least effective and reliable for this specific task?
