Final answer:
The correct response is to record the load and the failure mode when a specimen fails during testing. These details are essential for analyzing the material properties and understanding the specimen's performance under stress.
Step-by-step explanation:
When the specimens fail, record the load carried by the specimen during the test, and note the failure mode. The load refers to the force or weight that was being applied to the specimen when it failed, while the failure mode describes how the material broke or deformed, such as fracturing, shearing, or bending. Recording accurate information about both of these aspects is essential for analyzing material properties and the performance of the specimen under stress.
It is important to accurately document any observations during material testing, such as any physical changes in the specimen or any audible indications of failure. This process can help in understanding the stress-strain relationship and the mechanical properties of the material being tested.

This procedure is likely part of a density determination test in which the material's volume is determined by the water displacement method, allowing for the calculation of density by dividing the weight by the volume.
