P: modern system LP circuitry is more susceptible than the one in old system? recent days, one plan its signal is missing when one of its passenger use the laptop
C: the modern system has high risk than the old one because the use of the electronic devices.
Least support:
A:
(A) After the laptop computer was turned off, the
plane regained course and its navigation
instruments and dials returned to normal.-->support, no cause, no result.
(B) When in use all electronic devices emit
electromagnetic radiation, which is known to
interfere with circuitry.-->support, prove the evidence is reliable.
(C) No problems with navigational equipment or
instrument dials have been reported on
flights with no passenger-owned electronic
devices on board.-->support, no cause, no result
(D) Significant electromagnetic radiation from
portable electronic devices can travel up to
eight meters, and some passenger seats on
modern aircraft are located within four meters
of the navigation systems.-->support, prove the evidence is sufficient.
(E) Planes were first equipped with low-power
circuitry at about the same time portable
electronic devices became popular.-->weaken

我觉得是不是E还会有点weaken的成分，因为electron device 是在modern 用的时候才开始广泛使用的，所以说old 用的时候，electron device 用的少，所以没有veer off， 如果用的话也会veer off 的~所以说新的不一定比旧的更容易造成危险。

没觉出来有weaken的成份阿，后面的bala说的意思我没明白，怎么还联系到old上面去了。
从选项来看， low-power circuitry at about the same time portable electronic devices became popular应该也就是说这两个发生的时间是一样的，是在electronic device get popular的时候。顶多就是表示一个时间的关系，没有什么weaken的含义阿~
木有明白bala的解释~

我换个说法哈：看这个时间轴：vacuum-tube circuitry（old）------->low-power circuitry(new)+electronic
devices become popular.所以可以得出，以前vacuum-tube circuitry 使用的时候，electron devices 用的少，所以事故率低，如果用的和现在一样多的话，事故率也会增高的，所以我觉得会weaken。
