问题如下：
In constructing a chart, using a logarithmic scale on the vertical axis is likely to be most useful for which of the following applications?
选项：
A.
The price of gold for the past 100 years.
B.
The share price of a company over the past month.
C.
Yields on 10-year US Treasuries for the past 5 years.
解释：
A is correct.
The price of gold in nominal dollars was several orders of magnitude cheaper 100 years ago than it is today (roughly US$20 then versus US$1,100 today). Such a wide range of prices lends itself well to being graphically displayed on a logarithmic scale.
老师我想问下，这道题的lograthmatic是什么意思，为什么B不对，谢谢
