### HideShow timer Statistics

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.

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

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

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

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

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

option e ?

because the sentence in option e is arranged squentially and it also maintains its parallelism.

please correct me, if i m wrong.

+1 for B

Meaning:
A water strider can do two things
1) Can walk on the surface of water
2) Generate enough upward thrust with its legs to launch itself off the surface
These actions result in achieving one of the most complex manuevers

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 --> Not only X but also Y. X and Y must be parallel

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 --> Correct parallelism

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 --> changes the meaning

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 --> Parallelism error

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 --> Changes the meaning

Ans:- C
Insect can walk not only on the water's surface but also off the surface.
This walking generates thrust and achieves ....
Not only x but also y... X and Y should be parallel.

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 - incorect placement of 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 - Correct usage of idiomatic expressions "not only...but also..." and clear in meaning

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- Incorrect usage of NOT ONLY

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

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 - Incorrect meaning

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.

Meaning - The water strider is a species of semi-aquatic insects. The water strider can walk on water. The water strider can also generate enough upward thrust to launch itself off the surface of water, similar to a jump.

A,D, E - wrong parallel structure

B & C - C has wrong meaning, in C the two actions "of generating & of achieving" are separate, however they have a cause & effect relation. The generating of upward thrust results in one of the most complex physical maneuvers aka jump.

"AND" alone cannot be used as a connector to signify result of an action, you need to pair it with another connector (e.g. thus) to do that.

B is correct in meaning. It uses "thereby" to convey the result of the action preceding it.

If you marked C as correct answer, i suggest Ron's video on "Use of AND as a connector" from March 01, 2012, Thursday's with Ron Manhattan video. It will clarify the usage of AND.

Thanks,
GyM
