Every refinement must first satisfy the Holy Trinity of Grammar:
1. Tense Consistency: Does the improvement match the sentence's timeline?
2. Subject-Verb Agreement: Is the number (singular/plural) correct?
3. Parallel Structure: Are similar elements formatted identically?
Example:
Sometimes a sentence is grammatically correct but idiomatically weak. Look for correct Prepositional usage and Phrasal Verbs.
Trap: Using 'superior than' instead of 'superior to'.
Example:
Don't just look for 'an' answer; look for the Best answer.
Step 1: Compare the original part with Option A.
Step 2: If both are okay, check for Wordiness.
Hack: Shorter, more direct sentences are usually preferred in competitive exams.
Example:
In 15-20% of exam questions, the original sentence is already optimal. Don't force a change if the original satisfies all rules.
Check-list:
- No Tense shift?
- Pronouns clear?
- Prepositions correct?
