In 1995 Richard Stallman, a well-known critic of the patent system, testified in Patent Office hearings that, to test the system, a colleague of his had managed to win a patent for one of Kirchoff's laws, an observation about electric current first made in 1845 and now included in virtually every textbook of elementary physics.

A
B. laws, which was an observation about electric current first made in 1845 and it is
C. laws, namely, it was an observation about electric current first made in 1845 and
D. laws, an observation about electric current first made in 1845, it is
E. laws that was an observation about electric current, first made in 1845, and is

E项first made in 1845 不是修饰elevtric current吗？和A选项修饰的内容一样啊！怎么OG上说setting off the phrase first made in the1895 in commas distorts the meaning？

当然不一样~~~ A 选项的 first made in 1845 并没有用逗号隔开~~~

在A选项里，first made in 1845 是修饰 an observation
在E选项里，first made in 1845 变成了修饰 electric current

谢谢！看懂了~ A项make an observation
但怎么定语不紧跟被修饰对象啊？不会让人误解吗？

那是同位语.句子中指代同一事物的两个词、片语或子句，称同位关系。例如：My sister, Helen Wilson, will travel with me. 句中My sister和Helen Wilson指的是同一个人，它们是同位成分，后一成分通常叫做前一成分的同位语
在GMAT中,同位语修饰名词要优于定语从句修饰，更简洁.
