47. Group A and Group B each have 10 students taking an English oral test, with each student tested 5 times. The number of times each student passed is as follows:
\begin{tabular}{|l|l|l|l|l|l|l|l|l|l|l|}
\hline Group A & 4 & 1 & 2 & 2 & 1 & 3 & 3 & 1 & 2 & 1 \\
\hline Group B & 4 & 3 & 0 & 2 & 1 & 3 & 3 & 0 & 1 & 3 \\
\hline
\end{tabular}
(1) If passing 3 times or more (including 3 times) is the passing standard, then, the passing rate of $\qquad$ group is higher; (2) The oral test passing times of $\qquad$ group are more stable.
Answer: B; A
