Final answer:
The question is about the state of a valve when a brake handle is in the extreme left position, which relates to an unspecified mechanical or engineering system. Without further context, it's not possible to accurately determine the valve's state.
Step-by-step explanation:
The question pertains to the position of a brake handle and its corresponding valve state in a mechanical or engineering context, which could potentially refer to a component within a transportation system or machinery. While the specific system or machinery isn't named, and the numerical reference (13-98) lacks context, the question suggests that it requires an understanding of mechanical systems where handles control valve positions, such as in automotive, aircraft, or industrial engineering applications. Without additional context, it's not possible to provide a precise answer to what the valve state is when the brake handle is in the extreme left position, as this can vary depending on the specific design of the system.
