标题: OG11th----SC107

OG11th----SC107
The physical structure of the human eye enables it to sense light of wavelengyhs up to 0.0005 millimeters;infrared radiation,however,is invisible because its wavelegth---0.1 millimeters---is too long to be registered by the eye.

(c)infrared radiation,however,is invisible because its wavelength---0.1millimeters---is too long for the eye to register it
(e)however,infrared radiation has a wavelength---0.1millimeters---that is too long for the eye to register, thus making it invisible

答案是（A），但我觉得C，E也对，OG说指代有问题，没看出来。请N人赐教。谢了！
