First of all, thank you for submitting a QOD. Please don't be discouraged by the barrage of comments, but rather accept that by posting one of these, your words will be examined and parsed to the n-th degree. You may want to take this as a lesson that would apply to your work in general; a first assumption should probably NEVER be put forth as a definitive answer.
For example, "The database crashed because program X had a coding error." may be a disasterous thing to say if you don't absolutely know it's true. If it's not, you've left the real cause of the problem to possibly recur and you've also undercut your reputation with management and reduced your chances of cooperation from developers.
Yes, this was just a silly little quiz question, but (as you've now seen), erroneous statements presented as facts can blow up quite a storm.
