For each of 5 kinds of food, the graph above shows the percent of 800 people surveyed who said they enjoy that kind of food. Based on the info in graph, which of the following statements must be true?
I. Some of the people said they enjoy more than one kind of food
II. More than half the people said they enjoy Italian food.
III. All the people who said they enjoy mexican food also said they enjoy Italian food
BAR GRAPH: chinise 38%, French 11%, German 12% Italiain 55%, and mexican 39%
why II.?

55% is more than half, so II is true. The one most people get stuck on here (maybe you mistyped?) is I. The way you know that I is true is that the percents add up to more than 100%.
