PrepTest 115 - Section 4 - Question 12

Show summary

The higher a dam, the more exposed it is to forces that can cause it to collapse. ██ ███ ███████ ████████ ██ ████ █████ ████ ████ ████ ███ ████ ███ ██████ █████ ███ ███ ███ ██ ███ ████ ███ █████████ ████ ████ ████████ ██████ ███ ████ ██ █████ ████ ████████ ██ ████ ████ █████ ███ ██████ █████

"Surprising" Phenomenon

Taller dams are more vulnerable to forces that could cause a collapse, and most arch dams are very high, so why is it that shorter arch dams account for all of the recent arch dam collapses?

Objective

The correct answer must help explain why shorter arch dams have been the ones to collapse, despite the fact that the taller ones are subject to greater forces. The stimulus doesn’t provide information on how either type of dam is constructed or maintained, so it's possible that the taller dams are built to be more resilient, or that they’re better maintained.
