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 top 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

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

Choice E produces an illogical statement by using a restrictive clause introduced by that where a comma followed by the nonrestrictive "which" is required: a wavelength of 0.1 millimeters that is too long nonsensically suggests that not all wavelengths of 0.1 millimeters are too long for the eye to register.

237. It seems likely that a number of astronomical phenomena, such as the formation of planetary nebulas, may be caused by the interaction where two stars orbit each other at close range.

(A) may be caused by the interaction where two stars orbit each other

(B) may be caused by the interaction between two stars that each orbit the other

(C) are because of the interaction between two stars that orbit each other

(D) are caused by the interaction of two stars where each is orbiting the other

(E) are caused by the interaction of two stars orbiting each other

Choice C can be faulted because to form a passive construction, are should take a verb form such as caused rather than an adverb such as because. Also, the phrase two stars that orbit each other illogically suggests that there are two particular stars causing all the phenomena in question, rather than various sets of stars in various locations.

我怎么感觉234和237中的that，og给出的解释有矛盾呢，在234中是限定性到了237中成非限定性了？请nn指点，谢谢。
