Difficulty: Easy
Correct Answer: No error.
Explanation:
Introduction:
This problem checks overall clause structure, prepositional harmony, and number agreement. Sometimes the correct choice is recognizing that all segments work fine together.
Given Data / Assumptions:
Concept / Approach:
Ensure agreement ("results" with "are"), idiomatic prepositions ("improvement of the diet"), and coherent meaning. The sentence states that recognizing a fact yields observable results manifested in improved diet among the poor.
Step-by-Step Solution:
1) Number agreement: "results" (plural) with "are" is correct.2) "are seen in" is idiomatic when indicating locus of manifestation.3) "gradual improvement of the diet of the poor" is grammatically and semantically sound.4) No modifier is misplaced; the chain of prepositional phrases is coherent.
Verification / Alternative check:
Paraphrase: "Because people recognize this fact, we can see the results in the steady betterment of poor people's diet." This retains meaning and grammar.
Why Other Options Are Wrong:
Common Pitfalls:
Overcorrecting idiomatic but valid prepositions; mistaking complex noun phrases for errors.
Final Answer:
Option E (No error)
