So, are you implying that anything involving potentially "dangerous" stuff like rape, suicide, violence, drinking, war etc is to be reserved only for "serious" academic research and be left out of test questions?
Imagine a test question "To one liter of a water/alcohol mixture in 1:1 ratio half a liter of water is added. What is the new alcohol-to-water ratio?". A former alcohol addict might be "triggered" by this question - but would you exclude it from a test?
Or, in a history test, avoid asking questions about the Afghanistan war because the kid's father lost a leg in Afghanistan?
