Concepts tested here: Grammatical Construction + Tenses + Pronouns + Verb Forms + Awkwardness/Redundancy• The present perfect tense (marked by the use of the helping verb “has/have”) is used to describe events that concluded in the past but continue to affect the present.
• The simple past tense is used to refer to actions that concluded in the past.
• Information that is permanent in nature is best conveyed through the simple present tense.
• "do so" is the correct usage for referring to an action, and "do it" is the correct usage for referring to a noun.
• The infinitive verb form (“to + base form of verb" - "to + consider" in this sentence) is the preferred construction for referring to the intent or purpose of an action.
A: This answer choice incorrectly uses the simple past tense verb "was never applied" to refer to an action that concluded in the past but continues to affect the present; remember, the present perfect tense (marked by the use of the helping verb “has/have”) is used to describe events that concluded in the past but continue to affect the present, and the simple past tense is used to refer to actions that concluded in the past. Further, Option A incorrectly uses the present perfect tense verb "has been required" to refer to information that is permanent in nature; remember, information that is permanent in nature is best conveyed through the simple present tense, and the present perfect tense (marked by the use of the helping verb “has/have”) is used to describe events that concluded in the past but continue to affect the present. Additionally, Option A incorrectly uses "do it" to refer to the action "call a convention"; remember, "do so" is the correct usage for referring to an action, and "do it" is the correct usage for referring to a noun. Besides, Option A uses the present participle ("verb+ing" - "considering" in this case) to refer to the purpose of the action "call a convention"; remember, for referring to the purpose or intent of an action, the infinitive verb form (“to + base form of verb" is preferred over the present participle ("verb+ing" - "considering" in this sentence) construction.
B: This answer choice incorrectly uses the simple past tense verb "was never applied" to refer to an action that concluded in the past but continues to affect the present; remember, the present perfect tense (marked by the use of the helping verb “has/have”) is used to describe events that concluded in the past but continue to affect the present, and the simple past tense is used to refer to actions that concluded in the past. Further, Option B incorrectly uses the present perfect tense verb "has been" to refer to information that is permanent in nature; remember, information that is permanent in nature is best conveyed through the simple present tense, and the present perfect tense (marked by the use of the helping verb “has/have”) is used to describe events that concluded in the past but continue to affect the present. Additionally, Option B incorrectly uses "do it" to refer to the action "call a convention"; remember, "do so" is the correct usage for referring to an action, and "do it" is the correct usage for referring to a noun. Besides, Option B uses the phrase "for consideration" to refer to the purpose of the action "call a convention"; remember, for referring to the purpose or intent of an action, the infinitive verb form (“to + base form of verb") is the preferred construction. Option B also uses the passive construction "there has been a requirement", leading to awkwardness and redundancy.
C: This answer choice fails to form a complete sentence; as both "Under a provision of the Constitution that was never applied" and "whereby Congress is required...states" are both dependent clauses, this sentence lacks an independent subject. Further, Option C incorrectly uses the simple past tense verb "was never applied" to refer to an action that concluded in the past but continues to affect the present; remember, the present perfect tense (marked by the use of the helping verb “has/have”) is used to describe events that concluded in the past but continue to affect the present, and the simple past tense is used to refer to actions that concluded in the past. Additionally, Option C incorrectly uses "do it" to refer to the action "call a convention"; remember, "do so" is the correct usage for referring to an action, "do it" is the correct usage for referring to a noun. Besides, Option C uses the present participle ("verb+ing" - "considering" in this case) to refer to the purpose of the action "call a convention"; remember, for referring to the purpose or intent of an action, the infinitive verb form (“to + base form of verb" is preferred over the present participle ("verb+ing" - "considering" in this sentence) construction.
D: This answer choice fails to form a complete sentence; as both "Under a provision of the Constitution that was never applied" and "whereby Congress is required...states" are both dependent clauses, this sentence lacks an independent subject.
E: Correct. This answer choice acts upon the independent subject noun "Congress" with the active verb "is required" to form a complete thought, producing a complete sentence. Further, Option E correctly uses the present perfect tense verb "has never been applied" to refer to an action that concluded in the past but continues to affect the present and correctly uses the simple present tense verb "is required" to refer to information that is permanent in nature. Additionally, Option E correctly uses "do so" to refer to the action "call a convention". Besides, Option E uses the infinitive verb form ("to + base form of verb" - "to + consider" in this sentence) to refer to the purpose of the action "call a convention". Option E is also 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 (~2 minutes):
