History
History (from Greek ἱστορία, historia, meaning "inquiry, knowledge acquired by investigation") is the study of the past as it is described in written documents. Events occurring before written record are considered prehistory. It is an umbrella term that relates to past events as well as the memory, discovery, collection, organization, presentation, and interpretation of information about these events. Scholars who write about history are called historians.
Teachers
You seemed to be listening to me, not to find out useful information, but to try to catch me in a logical fallacy. This tells us all that you are used to being smarter than your teachers, and that you listen to them in order to catch them making mistakes and prove how smart you are to the other students. This is such a pointless, stupid way of listening to teachers that it is clear you are going to waste months of our time before you finally catch on that the only transaction that matters is a transfer of useful information from adults who possess it to children who do not, and that catching mistakes is a criminal misuse of time.
