Read this excerpt from Chapter Two of Jack London’s The Call of the Wild. Buck learned easily, and under the combined tuition of his two mates and Francois made remarkable progress. Ere they returned to camp he knew enough to stop at "h.o.," to go ahead at "mush," to swing wide on the bends, and to keep clear of the wheeler when the loaded sled shot downhill at their heels.

What is a good prediction question to ask after reading this excerpt?
Will Buck be a successful sled dog?
Are there other dogs helping pull the sled?
Will Francois teach the dogs commands?
Does the sled carry any cargo to the camp?
