Respuesta :
The answer is: "'You’ve changed lots, Jimmy. I never thought you were so tall by two or three inches.'"
The statement itself contains the evidence. By admitting his awe that Jimmy has changed a lot, it implies that he is surprised at what his friend has become. Primarily due to his appearance. In this statement, he pinpointed the change in his height.
I know this was asked almost a month ago but for any other students that search this in the future, the answer is actually "His hand was steady when he began to read, but it trembled a little by the time he had finished." I just finished the test and got this one wrong, but it told me the correct answer and this is it :)
