Detailed Explanations
(All explanations are gathered here. In each explanation, the correct answer is shown as a single word only.)
1. one
“One” substitutes for a singular countable noun previously mentioned (“proposal”). It refers to a different item of the same category, not the identical object. This is nominal substitution, a key cohesion strategy in academic writing.
2. so
“Do not so” substitutes for the verb phrase “agree with the recommendation.” So functions as a pro-form replacing the entire action. This is verbal substitution, avoiding repetition.
3. be
After verbs like “expect,” ellipsis often removes repeated complements. The full clause would be “expected them to be consistent.” Be completes the infinitive without restating the adjective phrase.
4. so
“Was so” substitutes for “criticized.” So replaces the passive verb phrase. This is verbal substitution in passive context, enhancing concision.
5. so
“Turned out to be so” substitutes for “controversial.” So replaces an adjective complement after linking verbs. This is adjectival substitution.
6. one
“One” replaces “framework.” It indicates another item of the same type, preserving cohesion while preventing lexical repetition.
7. so
“Did so” replaces “objected to the conclusion.” So functions as a verbal pro-form representing the entire predicate.
8. so
“Did not so” substitutes for “fail to replicate the findings.” So replaces the verb phrase in contrastive comparison.
9. were
“Not all were” omits the adjective “unrealistic.” The predicate complement is understood from context. Were maintains correct agreement and tense in auxiliary-only ellipsis.
10. so
“Was not so” substitutes for “accurate.” So replaces the adjective complement. This is adjectival substitution after linking verb “was.”
11. so
“Did so” replaces “perform better.” So substitutes for the verb phrase complement. This is common after auxiliary “did.”
12. one
“One” substitutes for “hypothesis.” It indicates a different member of the same category in comparative structure.
13. so
“Proved so otherwise” uses so as clause substitution for “the data were reliable.” So represents the entire previously assumed proposition.
14. so
“If they do so” substitutes for “challenge existing theories.” So replaces the action. This structure is frequent in academic cause-effect discussion.
15. be
After modal “would,” ellipsis removes repeated complement phrases. Be completes the infinitive structure without restating the adjective “comprehensive.”
