时间Wed Sep 6 12:30:29 2017
各位好，想请问这题大家都怎麽想的呢?
In a survey, 130 people were asked how many movies they had seen in the
preceding year. Their responses varied from 0 to 30 movies. The graphs above
show two different summaries of the samesurvey results. How many people
responded that they had seen 11 or 12 movies?

此题答案是给E，请问是为什麽呢?(˙A˙);
