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.
(A) they denounce the big government, saying government is doing too much and has become too powerful, while at the same time supporting
(B) they denounce big government- they say that government is doing too much and has become too powerful-but supporting at the same time
(C) they denounce big government, say that government is doing too much and it has become too powerful, while they support at the same time
(D) while they denounce big government, saying that government is doing too much and has become too powerful, at the same time supporting
(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
Meaning is crucial to solving this problem:Understanding the intended meaning is key to solving this question; the intended meaning of the crucial part of this sentence is that many people in the United States denounce the big government, in that they say the government is doing too much and has become too powerful, while at the same time they support many specific government programs for health care, education, and the environment.
Concepts tested here: Meaning + Modifiers + Grammatical Construction + Tenses + Parallelism• Semicolons and the “comma + conjunction” construction are used to link two independent clauses; commas are used to link an independent clause with a dependent one; comma cannot be used to join two independent clauses.
• Dashes are used in place of colons: to introduce a list, a definition/explanation, or an answer/solution.
• Any elements linked by a conjunction ("but" in this sentence) must be parallel.
• All elements in a list must be parallel.
• Habitual actions are best conveyed through the simple present tense.
• The simple present continuous tense is used to refer to actions that are currently ongoing and continuous in nature.
A: Correct This answer choice correctly acts upon the independent subject pronoun "they" with the active verb "denounce" to form a complete thought, leading to a complete thought. Further, Option A uses the phrase "saying government is doing too much and has become too powerful"; the construction of this phrase conveys that intended meaning - that many people in the United States denounce the big government,
in that they say the government is doing too much and has become too powerful. Moreover, Option A currently uses the simple present tense verb "denounce" to refer to habitual action. Further, Option A correctly uses commas to link the independent clause "they denounce the big government" to the dependent clauses "saying government is doing too much and has become too powerful" and "while at the same time supporting...the environment. Additionally, Option A avoids the parallelism errors seen in Options B and C, as it lists no elements together and maintains parallelism between "saying government is doing too much and has become too powerful" and "supporting...the environment".
B: This answer choice incorrectly uses dashes to join the independent clause "they denounce big government" to the independent clause "they say that government is doing too much and has become too powerful" and the dependent clause "but supporting at the same time...the environment"; remember, semicolons and the “comma + conjunction” construction are used to link two independent clauses; commas are used to link an independent clause with a dependent one; comma cannot be used to join two independent clauses, and dashes are used in place of colons: to introduce a list, a definition/explanation, or an answer/solution. Further, Option B fails to maintain parallelism between "denounce the big government" and "supporting at the same time...the environment"; remember, any elements linked by a conjunction ("but" in this sentence) must be parallel.
C: Trap. This answer choice alters the meaning of the sentence through the phrase "say that government is doing too much and it has become too powerful"; the construction of this phrase incorrectly implies that many people in the United States denounce the big government, and
as a separate action they say the government is doing too much and has become too powerful; the intended meaning is that many people in the United States denounce the big government,
in that they say the government is doing too much and has become too powerful. Further, Option C fails to maintain parallelism among "they denounce big government", "say that government is doing too much and it has become too powerful", and "they support...the environment"; remember, all elements in a list must be parallel.
D: This answer choice fails to form a complete sentence; "while they denounce big government", "saying that government...become too powerful", and "at the same time...the environment" are all dependent clauses, so there is no independent subject for these clauses to modify.
E: This answer choice incorrectly uses dashes to join the independent clause "they say that government is doing too much and has become too powerful" to the dependent clauses "while they are denouncing big government" and "supporting at the same time...the environment"; remember, semicolons and the “comma + conjunction” construction are used to link two independent clauses; commas are used to link an independent clause with a dependent one; comma cannot be used to join two independent clauses. Further, Option E incorrectly uses the simple present continuous tense verb "are denouncing" to refer to a habitual action; remember, habitual actions are best conveyed through the simple present tense, and the simple present continuous tense is used to refer to actions that are currently ongoing and continuous in nature.
Hence, A is the best answer choice.Additional Note: Please note that in Option A "saying government..." and "at the same time supporting..." are not joined by the conjunction "while"; rather both are subordinate actions to "denounce the big government"; "while" is actually used to convey a sense of concurrence between "denounce" and "supporting".
