What is wrong with this sentence and why? My colleagues supported my proposal for two reasons: first, it is practical and second, its simplicity. a. The sentence does not use parallel structure because "it is practical" and "its simplicity" are not parallel. b. The colon should be a comma because the phrases before and after are closely related. c. First and second should be in parentheses since they introduce items in a list.

Read the excerpt from part 3 of the call of the wild. but it was in giving the law and making his mates live up to it, that buck excelled. dave and sol-leks did not mind the change in leadership. it was none of their business. their business was to toil, and toil mightily, in the traces. so long as that were not interfered with, they did not care what happened. billee, the good-natured, could lead for all they cared, so long as he kept order. the rest of the team, however, had grown unruly during the last days of spitz, and their surprise was great now that buck proceeded to lick them into shape. what theme is most supported by the ideas in this excerpt? good leaders are strong and intelligent. loyalty can be a very powerful force. only the strong survive in the wilderness. we are all ruled by our natural instincts.
