饼图显示了 A 学校和 B 学校学生最喜欢的零食。 下面的每个陈述要么是正确的，要么是错误的，要么是根据所给信息无法判断的。对于每个陈述，在正确的列中打勾（$\_$）。

陈述	正确	错误	无法确定
A 学校和 B 学校中选择糖果作为最喜欢零食的学生人数相等。
B 学校中 $\frac{3}{4}$ 的学生选择巧克力和糖果作为他们最喜欢的零食。

1. Evaluate the first statement regarding the number of students who chose candy.

Both pie charts show that $20\%$ of students chose candy. However, the total number of students in School A and School B is not given. Therefore, we cannot determine if the actual number of students is equal. The statement is 'Not possible to tell'.

2. Evaluate the second statement regarding the fraction of students in School B who chose chocolates and candy.

In School B, the fraction of students who chose chocolates is $\frac{1}{2}$ ($50\%$) and candy is $20\%$.
Total percentage = $50\% + 20\% = 70\%$.
The statement claims the fraction is $\frac{3}{4}$, which is equivalent to $75\%$.
Since $70\% \neq 75\%$, the statement is 'False'.
