标题: it在一句话里只能指代一个事物?

234. The physical structure of the human eye enables it to sense light of wavelengths up to 0.0005 millimeters; infrared radiation, however, is invisible because its wavelength—0.1 millimeters—is too long to be registered by the eye.


(A) infrared radiation, however, is invisible because its wavelength—0.1 millimeters—is too long to be registered by the eye


(B) however, the wavelength of infrared radiation—0.1 millimeters—is too long to be registered by the eye making it invisible


(C) infrared radiation, however, is invisible because its wavelength—0.1 millimeters—is too long for the eye to register it


(D) however, because the wavelength of infrared radiation is 0.1 millimeters, it is too long for the eye to register and thus invisible(A)


(E) however, infrared radiation has a wavelength of 0.1 millimeters that is too long for the eye to register, thus making it invisible


这样看来用分号隔开的一句话,各自的it可以指代不同的事物?(按A的说法,分号前的it指eye,分号后的之radiation.)

不好意思,无法解释,可能ETS认为分号可以。

分号隔开的两个句子应该都是完整的、独立的句子,所以同一个代词应该可以指代不同的事物。
