Hi, in A] the doer of action ''supporting'' is far away after crossing the verb. How do I understand this?
Hi fozzy,
This is in response to your PM. Although many people have arrived at the correct answer, let me describe it in a little more detail as to how to eliminate the incorrect answer choices and why the correct one is indeed correct.
A recent poll indicates that many people in the United States hold a combination of conservative and liberal political views; i.e.,
they denounce big government, saying government is doing too much and has become too powerful, while at the same time supporting many specific government programs for health care, education, and the environment.
MEANING ANALYSIS:According a recent poll, many people in the US have combination of conservative and liberal political views. They denounce big government for two reasons:
a. government is doing too much
b. government has become too powerful
But at the same time, they support many government health care, education, and environment programs.
ERROR ANALYSIS:If we carefully study the structure of the underlined portion of this sentence, we will see it uses the structure – They denounce A while… supporting B. The same structure can be seen in
OG 12 & 13#134 - Recently implemented "shift-work equations" based on studies of the human sleep cycle have reduced sickness, sleeping on the job, and fatigue among shift workers while raising production efficiency in various industries.
The above correct sentence employs the same structure – “Shift-work equations have reduced… while raising…”
The semicolon is correctly followed by an IC.
Comma + verb-ing modifier “saying” correctly modifies the preceding clause. The parallelism is maintained between the two reasons stated for denouncing the government.
Also, the simultaneous action has been correctly written by using “while”. The phrase
at the same time” just lays more emphasis on this simultaneity of actions. This sentence has no errors.
PoE:(A) they denounce the big government, saying government is doing too much and has become too powerful, while at the same time supporting:
Correct as is for the reason stated above.
(B) they denounce big government- they say that government is doing too much and has become too powerful-but supporting at the same time:
Incorrect. Use of “but” brings in contrast here. The intention is to talk about the simultaneity of actions. This is the reason why, in choice “while” has been followed by “at the same time”.
(C) they denounce big government, they say that government is doing too much and it has become too powerful, while they support at the same time:
Incorrect. The two ICS are connected by comma. This is a run-on sentence.
(D) while they denounce big government, saying that government is doing too much and has become too powerful, at the same time supporting:
Incorrect. There is no IC after semicolon.
(E) while they are denouncing big government- they say that government is doing too much and it has become too powerful-supporting at the same time:
Incorrect. Same error an in Choice D.
Hope this helps.

Thanks.
