Concepts tested here: Tenses + Idioms + Awkwardness/Redundancy• The simple past tense is used to refer to actions that concluded in the past.
• The past perfect tense (marked by the use of helping verb "had") is used when a sentence contains two actions in the past; the helping verb "had" is used with the action in the "greater past".
• “that” is used to provide information needed to preserve the core meaning of the sentence, and the “comma + which” construction is used to provide extra information.
• "ability to" is the preferred construction.
A: Correct.1/ This answer choice correctly uses the simple past tense verb "did" to refer to an action that concluded in the past.
2/ Option A avoids the idiomatic error seen in Option C, as it directly modifies "burden" with "it once did", without using "that" or "which".
3/ Option A correctly uses the idiomatic construction "ability to".
4/ Option A is free of any awkwardness or redundancy.
B:1/ This answer choice incorrectly uses the past perfect tense verb "had (carried)" to refer to an action that concluded in the past; remember, the simple past tense is used to refer to actions that concluded in the past, and the past perfect tense (marked by the use of helping verb "had") is used when a sentence contains two actions in the past; the helping verb "had" is used with the action in the "greater past".
C:1/ This answer choice incorrectly uses the past perfect tense verb "had (carried)" to refer to an action that concluded in the past; remember, the simple past tense is used to refer to actions that concluded in the past, and the past perfect tense (marked by the use of helping verb "had") is used when a sentence contains two actions in the past; the helping verb "had" is used with the action in the "greater past".
2/ Option C incorrectly uses "which" to refer to information needed to preserve the core meaning of the sentence; remember, “that” is used to provide information needed to preserve the core meaning of the sentence, and the “comma + which” construction is used to provide extra information.
3/ Option C uses the needlessly indirect construction "able no longer", leading to awkwardness.
D:1/ This answer choice incorrectly uses the past perfect tense verb "had (carried)" to refer to an action that concluded in the past; remember, the simple past tense is used to refer to actions that concluded in the past, and the past perfect tense (marked by the use of helping verb "had") is used when a sentence contains two actions in the past; the helping verb "had" is used with the action in the "greater past".
2/ Option D incorrectly uses the unidiomatic construction "ability for"; remember, "ability to" is the preferred construction.
3/ Option D uses the needlessly wordy construction "having the ability of carrying", leading to awkwardness and redundancy.
E:1/ This answer choice incorrectly uses the unidiomatic construction "ability for"; remember, "ability to" is generally preferred over "ability for".
2/ Option E incorrectly uses the unidiomatic construction "ability of"; remember, "ability to" is the preferred construction.
3/ Option E uses the needlessly wordy construction "with the ability of carrying", leading to awkwardness and redundancy.
