The first two of the questions in (2) refer to some nonspecific time in the past; question (2c) asks more directly for the time - the event time - when the event mentioned (the building of the structure) took place. Question (1) about when the respondent first experienced back pain lasting a week or more is also an example of this type. The answers to such questions are largely independent of the interview time (so long as the target event preseded the interview). They require respondents to search their memory for information about individual events of the specified type and to compose their answers on the basis of this infomation.

Yes, both of them are. Beowulf is the superhuman hero, who is a typical figure for an epic. He kills monsters, saves the realm, finally gets to rule one, etc. But he is ultimately alone in his heroism. As for Wiglaf, he is a prototype of a courageous warrior loyal to his king. He is the only one who comes to Beowulf's aid in his fight with the dragon. Epics always have these loyal and devoted followers of the main heroes, just like they have disloyal, cowardly people who abandon their ruler in his hour of need.
