I have two questions.
It is important to remember that Jacob Marley was dead. Did Scrooge know that? Of course he did.
Scrooge and Marley had been partners in London for many years, and excellent men of business they were, too.
Q. I have no idea why there is "they were" at the end of the sentence."// If "they were" is gotten rid of ,I think, the sentence will be a perfect sentence. I think the sentence have useless words(="they were" ) now.
Q. What do "they" mean? Scrooge and Marley?
