Which excerpt from The Call of the Wild is an example of direct characterization? “Dave refused to run quietly on the trail behind the sled, where the going was easy, but continued to flounder alongside in the soft snow, where the going was most difficult, till exhausted.” “But Mercedes interfered, crying, ‘Oh, Hal, you mustn’t,’ as she caught hold of the whip and wrenched it from him. ‘The poor dears! Now you must promise you won’t be harsh with them for the rest of the trip, or I won’t go a step.’” “‘Mush on, poor sore feets,’ the driver encouraged them as they tottered down the main street of Skaguay. ‘Dis is de las’. Den we get one long res’. Eh? For sure. One bully long res’.’” “But the Outside dogs, though practically broken in since their landing, did not amount to much. Three were short-haired pointers, one was a Newfoundland, and the other two were mongrels of indeterminate breed.”
