Answer 1

"ceewill has it right except the first answer. It was the Fourth century CE when the date for Christmas became firmly set - not based on any idea of when Jesus was actually born but for other reasons as cited in the Wiki source below. ( I see it's the same one as "ceewill")
Bing Crosby's "White Christmas" has been the most popular recorded version.
Your teacher's question makes Albert seem like a kept man - a "consort" - though I suppose that is the correct term. He was Queen Victoria's husband and father of their 9 kids.

Answer 2

What century: I think this is open to conjecture but possibly the 1st century (see: http://en.wikipedia.org/wiki/Christmas). However, I would also point out that the various Eastern Orthodox churches celebrate Christ's birth in January.

Christmas single: White Christmas

Christmas tree: Prince Albert

Victorian novel: A Christmas Carol

Edit: In response to Spreedog's reply below: Oops! I got a little confused; I had the following in mind when I wrote my answer, which even so would mean I should have written the third century (which wasn't even an option): "Sextus Julius Africanus popularized the idea that Jesus was born on December 25 in his Chronographiai, a reference book for Christians written in AD 221. This date is nine months after the traditional date of the Incarnation (March 25), now celebrated as the Feast of the Annunciation. March 25 was considered to be the date of the vernal equinox and therefore the creation of Adam; early Christians believed this was also the date Jesus was crucified. The Christian idea that Jesus was conceived on the same date that he died on the cross is consistent with a Jewish belief that a prophet lived an integral number of years."
