When a General Knowledge quiz etcet have answers that require a lot of depth, it can be just called 'Knowledge' since the generality is lost.
Not looking forward to this weekend, the infamous Tennis Club General Knowledge Quiz is happening, and my brother and sister-in-law and wife all want to go.
You mean the 'Knowledge' quiz?
Nothing is free, not even knowledge. Usually somebody who thinks knowledge should be free is a thief looking to make money off what somebody else knows.
