AI Explanation
The correct answer is A) provide an alternate means of determining the water level, if the gage glass fails. Try-cocks are used on auxiliary boilers as a backup method to visually verify the water level in the boiler, in case the primary water level gage glass becomes inoperable. This ensures the boiler operator can still monitor the water level and make necessary adjustments to maintain a safe water level, even if the gage glass fails. The other answer choices do not accurately describe the primary purpose of try-cocks on an auxiliary boiler.
