True or False: Expert systems typically require manual input without any automation.

The statement is false because expert systems are designed to replicate the decision-making ability of a human expert. Typically, they are equipped to automate inputs and processes to generate conclusions or recommendations based on the data and rules they have been programmed with. While they may sometimes require initial data input from users, the main function of expert systems is to utilize that input to perform automated reasoning and provide outputs without needing continuous manual interaction. They often incorporate mechanisms for learning and adapting, which further enhances automation.

In contrast, the other options imply different levels of manual input, but expert systems as a whole aim to minimize the necessity for ongoing manual input, thus emphasizing their automated nature.
