Meaning is crucial to solving this problem:Understanding the intended meaning is key to solving this question; the intended meaning of this sentence is that gusty westerly winds will continue to usher in a seasonably cool air mass into the region, and simultaneously, a broad area of high pressure, which will bring fair and dry weather for several days, will build.
Concepts tested here: Meaning + Verb Forms + Awkwardness/Redundancy• The simple future tense is used to refer to actions that will take place in the future.
• The simple present tense is used to indicate actions taking place in the current time frame, indicate habitual actions, state universal truths, and convey information that is permanent in nature.
• For referring to purpose/intent of action the infinitive verb form ("to +base form of verb") is preferred over the present participle ("verb+ing").
• The introduction of present participle ("verb+ing"- “building” in this case) after comma generally leads to a cause-effect relationship.
• Any elements linked by a conjunction ("and" in this sentence) must be parallel.
A: This answer choice redundantly uses "in" alongside "into", rendering it awkward and needlessly wordy.
B: This answer choice alters the meaning of the sentence through the phrase "and a broad area of high pressure will build"; the construction of this phrase incorrectly implies that gusty westerly winds will continue to usher in a seasonably cool air mass into the region, and
at an indeterminate time a broad area of high pressure, which will bring fair and dry weather for several days, will build; the intended meaning is that gusty westerly winds will continue to usher in a seasonably cool air mass into the region, and
simultaneously, a broad area of high pressure, which will bring fair and dry weather for several days, will build. Moreover, Option B incorrectly uses the simple present tense verb "bring" to refer to a future action; please remember, the simple future tense is used to refer to actions that will take place in the future, and the simple present tense is used to indicate actions taking place in the current time frame, indicate habitual actions, state universal truths, and convey information that is permanent in nature. Further, Option B uses the present participle ("verb+ing" - "ushering" in this case) to refer to the intent of the action "continue"; please remember, for referring to purpose/intent of action the infinitive verb form ("to +base form of verb") is preferred over the present participle ("verb+ing"). Additionally, Option B redundantly uses "in" alongside "into", rendering it awkward and needlessly wordy.
C: This answer choice alters the meaning of the sentence through the phrase "a broad area of high pressure building"; the use of the "comma + present participle ("verb+ing" - "building" in this case) incorrectly implies that gusty westerly winds will continue to usher in a seasonably cool air mass into the region, and
as a result, a broad area of high pressure will build and bring fair and dry weather for several days; the intended meaning gusty westerly winds will continue to usher in a seasonably cool air mass into the region, and
[b]simultaneously, as a separate action[/b] a broad area of high pressure, which will build and bring fair and dry weather for several days; remember, the introduction of present participle ("verb+ing"- “building” in this case) after comma generally leads to a cause-effect relationship. Further, Option C fails to maintain parallelism between "building" and "bring"; please remember, any elements linked by a conjunction ("and" in this sentence) must be parallel.
D: This answer choice alters the meaning of the sentence through the phrase "with a broad area of high pressure building"; the use of the "comma + present participle ("verb+ing" - "building" in this case) incorrectly implies that gusty westerly winds will continue to usher in a seasonably cool air mass into the region, and
as a result, a broad area of high pressure will build and bring fair and dry weather for several days; the intended meaning gusty westerly winds will continue to usher in a seasonably cool air mass into the region, and
[b]simultaneously, as a separate action[/b] a broad area of high pressure, which will build and bring fair and dry weather for several days; remember, the introduction of present participle ("verb+ing"- “building” in this case) after comma generally leads to a cause-effect relationship. Further, Option D fails to maintain parallelism between "building" and "bring"; please remember, any elements linked by a conjunction ("and" in this sentence) must be parallel. Additionally, Option D uses the present participle ("verb+ing" - "ushering" in this case) to refer to the intent of the action "continue"; please remember, for referring to purpose/intent of action the infinitive verb form ("to +base form of verb") is preferred over the present participle ("verb+ing").
E: Correct. This answer choice uses the phrase "while a broad area of high pressure builds", conveying the intended meaning - that gusty westerly winds will continue to usher in a seasonably cool air mass into the region, and simultaneously, a broad area of high pressure, which will bring fair and dry weather for several days, will build. Moreover, Option E correctly uses the simple future tense verb "will bring" to refer to an action that will take place in the future. Further, Option E avoids the parallelism error seen in Option C and D, as it does not employ a conjunction. Additionally, Option E uses the infinitive verb form ("to + base form of verb" - "to + usher" in this sentence)" to refer to the intent of the action "continue". Besides, Option E is free of any awkwardness or redundancy.
Hence, E is the best answer choice.To understand the concept of "Simple Tenses" on GMAT, you may want to watch the following video (~1 minute):
