The water strider, a species of semi-aquatic insects, can not only walk on the surface of water but also can generate enough upward thrust with its legs to launch itself off the surface, by achieving one of the most complex physical maneuvers - jumping on water.
First understand the sentence what it has to say-
Water strider can do -1) walk on the surface of water
2) generate enough upward thrust which leads its leg to launch itself off the surface
A) can not only walk on the surface of water but also can generate enough upward thrust with its legs to launch itself off the surface, by
WRONG Parallelism error- can not only but also can- it should be not only can but also can
B) not only can walk on the surface of water but also can generate enough upward thrust with its legs to launch itself off the surface, thereby
WRONG Parallelism error corrected and no further error added
C) can walk not only on the surface of water but also off the surface, generating enough upward thrust with its legs to launch itself and
WRONG idiom but also with not only missing
D) not only can walk on the surface of water but also generate enough upward thrust with its legs to launch itself off the surface, thereby
WRONG Parallelism error not only can but also (can missing)
E) can not only walk on the surface of water, generating enough upward thrust with its legs to launch itself, but also walk off the surface, thereby
WRONG Changes the meaning of the sentence here it says -
Water strider can do -1) walk on the surface of water, generating enough upward thrust with its legs to launch itself ( does not answer the question
launches where?)
2)walk off the surface
