Machines replacing human labor

[gmat740]

Machines replacing human labor, there was wide anticipation that the workweek would continue to become shorter.

(A) Machines replacing human labor, there was wide anticipation that
(B) When machines replaced human labor, there was wide anticipation
(C) As machines replaced human labor, it was widely anticipated that
(D) Insofar as machines replaced human labor, it was widely anticipated
(E) Human labor being replaced by machines, there was wide anticipation that

IMO "C".

B and D are missing "that".

For "A" and "E"...we need sth like...."With machines..."...

and "E" there is "being" which although not always wrong....but is a reason of suspicioun.

(E) Human labor being replaced by machines, there was wide anticipation that

A -> missing conjunction
B,D -> that needed
E -> passive, missing conjuction

C is the best choice

Hi Rahul,

Although I also had same reasoning similar to yours....but can you please help me understand it in more detail....i.e. I am not sure what is meant by conjuction in A,E....and why exactly the same is required....

From the sentence structure I can make out...but can you please help me understand the language/grammar reason for the same ?

Similar why exactly "that" is needed in "B" and "D"....again here too I can make out from sentence structure that "that" is required...but what is the grammar/language rule behind the same....

Thanks
Mohit

hey i meant to say subordinators, not conjunction, got confused..
Subordinators can attach a subordinate clause to the main clause

as in I am good at football, i like watching cricket. This sentence is wrong as it is run-on. One part should be main clause and other subordinate.
this sentence requires a subordinator ( such as although, because, but) to make it complete.
although i am good at football, i like watching cricket. or
because i am good at football, i like watching cricket. (don't go by meaning
)

that which is missing in choice B and D above is required when to introduce a clause
