问题如下：
The severity distribution of operational losses usually has the following shape:
选项： A. Symmetrical with short tails
B. Long-tailed to the right
C. Uniform
D. Symmetrical with long tails
解释：
B is correct. Loss severity distributions are bounded by zero but should include very large losses. So, they are asymmetrical with long right tails.
我以为是要把right改成left才对 一般画图不是左边肥尾吗
