Read the excerpt, and then answer the question. "mr. gray was thirty-eight, and tall and slender…unsentimental, and with that kind of trim-chiseled face that just seems to glint…with frosty intellectuality! " "a dog's tale." mark twain, 1904. based on the excerpt, the narrator's description most reinforces which of mr. gray's character traits? a. fitness b. spitefulness c. understanding d. heartlessness

Personally, I'd go with D. heartlessness.
It's not A, fitness, because we don't know if Mr. Gray was fit - we only know he was tall and slender; B is also wrong because the text says nothing about him being spiteful; C is wrong for the same reason. Thus, this leaves us with D, because the text says he is 'unsentimental,' which means the same as heartless. 

Even though Fred and George are twins they were of course born at different times so the twin born first is the middle child of the Weasley family
