What does The Ghost of Christmas Past answer when Scrooge asks him what business brought him here?

Scrooge has
been informed by Marley's ghost that he will be visited by spirits. When the Ghost of Christmas
Past arrives, Scrooge asks him if he is one of the spirits Marley told him would come. The ghost
says he is, and Scrooge then asks him why he is there. Rather than give him a specific answer,
the ghost simply says he has arrived for Scrooge's "reclamation."

Though Scrooge would rather not have had to deal with this ghost, he is also strangely
drawn to him and finds he can't resist when the spirit takes hold of his arm and tells him to
come with him.

Scrooge, at this point, has little idea of what is about to
happen to him or what his reclamation will consist of. Nevertheless, he travels with the ghost
to visit scenes from his past that will start to melt his long-frozen
heart.
