小提示：

从图中读出意大利面条和意式夹馅卷的条形高度

Read the spaghetti and manicotti bar heights from the graph.

大提示：

所求比值是意大利面条比意式夹馅卷，顺序不能反

The requested ratio is spaghetti to manicotti, in that order.

解答：

喜欢意大利面条的学生有 $250$ 人，喜欢意式夹馅卷的学生有 $100$ 人。

比值为 $\dfrac{250}{100} = \dfrac{5}{2}\text{。}$

所以正确答案是 E。

There are $250$ students who preferred spaghetti and $100$ that preferred manicotti.

The ratio is therefore $\dfrac{250}{100} = \dfrac{5}{2}.$

Thus, E is the correct answer.
