Final answer:
The statement is generally true; in certain technical situations such as aviation, if an engine stalls and won't clear, shutting it down and attempting a restart may be recommended, following safety protocols and operational guidelines.
Step-by-step explanation:
The question "True/False: If a stalled engine will not clear, you may shut down the engine and attempt a restart." pertains to procedures that might be followed in certain engineering or technical situations, such as aviation or automotive troubleshooting. In many instances, especially in aviation, if an engine gets stalled and normal troubleshooting procedures fail to clear the issue, it is often recommended to shut down the engine safely and attempt a restart, provided the circumstances allow for such an action to be taken safely. However, the specific procedures may vary based on the type of machinery, the situation at hand, and safety protocols. It is crucial to refer to the operating manual or guidelines for the specific machinery you are operating. For educational purposes and generally accepted practices, the statement can be considered true, with the provision that any such action should follow safety protocols and operational guidelines.
