A tall person can cover distance quickly , presumably Em will be slow .None of the above choices .Em did a little magic with the wand to make herself short .Em transformed into a person one foot shorter and walked quickly .
Why is it interesting to know Em 's height ?
She 's big on magic wands and transformation right now . Em felt she was running a little late , so she said , " We 'll walk quickly . " She did . I had to stretch my legs a bit to keep her pace , and she was shorter than me by a foot and was wearing a pack .
