Answer:
Scrooge wants to know if he can erase the writing on his gravestone.
Step-by-step explanation:
In the comic, Scrooge was terrified to see his name on the gravestone. He prays to the spirit if there is anyway he can change, any way to erase that writing on his gravestone. In the illustrations, Scrooge is lying on his knees praying to the Ghost of Christmas Yet to Come. He says "I will honor Christmas in my heart and try to keep it all year! I will live in the Past, Present, and Future! The spirits of all three shall strive within me! I will not shut out the lessons they have taught. Oh tell me-- Tell me that I may erase the writing on this stone!"
Hence, Scrooge wants to know if he changes, he can erase the writing on his gravestone in the future.
