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 wavelengths0.1 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 radiationıhowever 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 millimetersıit 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

(C) infrared radiationıhowever is invisible because its wavelength-0.1 millimeters-is too long for the eye to register it ----> words like however, therefore should be followed by a comma

(D) however because the wavelength of infrared radiation is 0.1 millimetersıit is too long

for the eye to register and thus invisible

IMO A,

";" indicates both the clauses should be independent...drop D,
Op E you please edit as u missed some part...

Op B, -ing form without COMMA modifies the preceding noun..so here making is modifying eye...so that means eye making it invisible...nonsensical

Op A and Op C are close contender, though its always painful to pick the choice which is passive but still i picked Op A....i learned some concept and it worked and helped me when to pick passive....

When a passive voice is preferred???

Case 1:-- When the subject of the sentence is Indefinite, general or is unimportant.

ex:- they mine the coal in Asansol. (active voice---poor)

the subject is indefinite and it is not clear what is meant by THEY.

Coal is mined in Asansol. (passive and better)

Case 2:-- WHAT WAS DONE is more important.

Ex:- Columbus discovered America (active---poor)

America was discovered by Columbus (passive--better)

Now coming back to the question...see

If you say,

1. eyes register infrared....(active voice)

2. Infrared registered by the eye...(passive voice)

Though m saying this wrong because its the wavelength not infrared which is registered but that doesn't make sense on what i wanna explain...so please ignore this thought

Now how to select between these two...as i mentioned earlier..when what was done is more important rather than the subject of active voice....one more hint..if you see this "is invisible because its wavelength-0.1..." this is describing INFRARED..so it should come first...

hence the correct structure is

Infrared..is bla bla bla...to be registered by the eye...

This is my opinion...correct me if m wrong.

Thanks
