Pressing the MASTER WARN or MASTER CAUT switchlight in either cockpit extinguishes the lamp and rearms the mechanism for additional malfunctions or failures. Is this statement true or false?

The statement is true because pressing the MASTER WARN or MASTER CAUT switchlight in the T-6B aircraft does indeed extinguish the respective lamp and rearm the system for any additional malfunctions or failure warnings that may occur. This functionality is designed to ensure that pilots are made aware of any critical alerts or warnings in the system while allowing them to acknowledge existing alerts without losing subsequent notifications. Thus, pressing these switchlights enables the pilots to maintain awareness of aircraft status effectively, which is crucial for safety and operational efficiency during flight.
