Final answer:
Technician A is correct that some feeler gauges come in a bent arrangement for cramped spaces. Technician B is correct that feeler gauges can be stacked to achieve a desired thickness.
Step-by-step explanation:
Technician A is correct that some feeler gauges come in a bent arrangement to be more easily inserted in cramped spaces. This allows for better access when measuring gaps in tight spots. Technician B is also correct that two or more feeler gauges can be stacked together to make up a desired thickness. This is commonly done to achieve a specific measurement when a single feeler gauge is not available in the desired thickness.
