Sentence Improvement & Sentence Completion: The Complete Expert System

Part 1: Sentence Improvement — Understanding the Format

In Sentence Improvement questions, a sentence is given with an underlined portion. You're given 4 options to replace the underlined part, plus an option "No improvement needed." You must select the option that makes the sentence grammatically correct and stylistically better.

The "No Improvement" Trap — The Most Critical Rule

30-35% of Sentence Improvement questions have "No Improvement" (option D or E) as the correct answer. This is where aspirants lose the most marks because they:

• Assume every sentence must have an error (wrong assumption)
• Change correct sentences because "the other options look more formal"
• Confuse British English vs American English usage (both can be correct)

Rule: Before selecting any replacement option, ask yourself: "Is the original sentence grammatically correct AND is the meaning clear?" If yes to both — the answer is "No Improvement." Don't change what isn't broken.

Also remember: Stylistic changes (making writing more "flowery" or "formal") do NOT qualify as sentence improvement in competitive exams. Only grammatical errors count.

The 6-Check System for Sentence Improvement

When you see the underlined portion, quickly run through these 6 checks on it:

1. Check 1 — Tense: Is the tense consistent with the time indicators in the sentence? ("since" = perfect, "ago" = simple past, "by tomorrow" = future perfect)
2. Check 2 — Subject-Verb Agreement: Does the verb agree with the grammatical subject (not the nearest noun)?
3. Check 3 — Pronoun Case: Is the pronoun in the correct case? (Subject: I/he/she/they vs Object: me/him/her/them)
4. Check 4 — Preposition: Is the correct preposition used? (At, in, on for time and place have specific rules)
5. Check 5 — Parallel Structure: If the sentence has a list, are all items in the same grammatical form? ("He likes running, swimming, and to play tennis" → wrong. Should be "running, swimming, and playing.")
6. Check 6 — Redundancy/Conciseness: Does the underlined portion contain unnecessary repetition?

Parallel Structure Rules

This is the silent marks-killer in Sentence Improvement. When a sentence lists actions, comparisons, or qualities, all elements must be in the same grammatical form:

• Wrong: "She enjoys singing, dancing, and to cook." → Right: "singing, dancing, and cooking."
• Wrong: "He is intelligent, hardworking, and has ambition." → Right: "intelligent, hardworking, and ambitious."
• Wrong: "The report was long, complex, and lacked clarity." → Right: "long, complex, and unclear."

Part 2: Sentence Completion — Finishing Strong

Sentence Completion gives you the first half of a sentence and asks you to choose the best ending from 5 options. The challenge: multiple options may seem grammatically correct — you must pick the one that best preserves meaning, tone, and logic.

4-Step Sentence Completion Strategy:

1. Before reading options: Cover the options and complete the sentence in your own words. This prevents options from biasing your judgment.
2. Identify the sentence direction: Does the first half suggest a contrast (need "however/but"), a consequence (need "therefore"), or a continuation?
3. Grammar filter: The completion must be grammatically correct. Eliminate options with wrong tense, wrong pronoun, or broken parallel structure.
4. Best-fit test: Among the grammatically correct options, choose the one that is most logically consistent with what the first half implies — not just any valid completion.

The "Best-Fit" vs "Technically Correct" Distinction

This is where top scorers separate from average scorers. Example:

Options A, B, C, and D are all grammatically correct. But the signal word "Although" requires a contrast — the second half must contradict the first half (thorough preparation). Option C provides the required contrast (prepared thoroughly → still failed). Options A and D AGREE with thorough preparation (wrong direction). Option B is irrelevant.

Answer: C — Always look for the contrast/agreement signal first.
