Answer:
1. A marketer is speaking throughout the poem. You can tell the speaker is simply trying to do his job in the place where he lives and is very cheery and joyous in the poem.
2. The poem is about a local marketer trying to sell his wares in the busy London-town.
3. The speaker has a cheery tone. You can tell by the way he says things like, "Let non despise the merry, merry cries of famous London-town!" Glad to be there.
4. Since I don't have access to the lesson you have I'm going to guess the time period is around the 19th century.
5. The speaker creates an image of a busy and cheerful town, full of a variety of people and things you can gather from it.
I hope this helps.
