Sentence Improvement

Concept

Sentence Improvement questions give you a full sentence and four alternative ways to phrase part or all of it. Your job is to pick the version that best improves the original — keeping the meaning intact while making it clearer, more concise, grammatically sound, or more idiomatic. The original sentence always has something wrong with it: it may be wordy, grammatically incorrect, stylistically awkward, or just not the best way to express the idea.

The crucial principle is meaning preservation. You cannot change what the sentence means. If Option C makes the sentence more concise but subtly shifts the meaning (say, from “might” to “will”), it’s wrong. The improvement must be purely about expression quality, not about changing the message.

GATE tests your ability to recognize what makes English sentences work well: they should be direct, use the right word for the job, avoid unnecessary filler, and follow the natural order of ideas. Technical writing especially favors brevity and precision — the kind of clean prose that gets information across without wasting the reader’s time.

Types & Approach

Redundant Expressions — The most common improvement target. Sentences often contain two words that say the same thing. “Past history,” “future plans,” “absolutely essential,” “completely eliminate,” “end result,” “free gift,” “new innovations,” “refer back.” Remove one of the redundant pair.

Wordy Constructions — Simple ideas dressed up in unnecessary words. “Due to the fact that” → “because.” “In order to” → “to.” “At this point in time” → “now.” “It is important that” → often just state the thing directly. The improved version usually has fewer words and more direct structure.

Awkward Phrasing — Sometimes grammatically correct but hard to parse. Passive voice isn’t automatically wrong, but active voice is usually clearer. Long sentences with embedded clauses can be broken up. Look for the option that makes the sentence easier to read at a glance.

Incorrect Grammar Disguised as Improvement — Some options try to “fix” something that isn’t broken, or introduce a new error while fixing the original. Watch for tense shifts that change meaning, subject changes that affect agreement, and idiom violations.

Idiom Errors — Prepositions and fixed phrases. “Comply to” should be “comply with.” “An interest in” not “an interest for.” These need to be memorized or recognized by feel.

Step-by-Step Example

Q: “The experiment failed due to the fact that the sample was contaminated.” Approach: Step 1 → Identify redundancy: “due to the fact that” is wordy for “because.” Step 2 → Check if any option introduces a new error: Option B replaces with “because,” which is cleaner. Step 3 → Confirm meaning: both express the same cause-effect relationship. Answer: (B) because — removes unnecessary wordiness while preserving meaning.

Common Mistakes

• Choosing the shortest option blindly — sometimes the original length is necessary for precision. “Due to the fact that” vs “because” — the second is always better, but “The experiment, which cost millions, failed” is not improved by shortening to “The experiment failed.”
• Falling for grammatically correct but idiomatically wrong options — “comply to” is wrong even if it sounds formal.
• Forgetting that the “no improvement” option (often Option D or E) exists and is sometimes correct. If the original is genuinely fine, pick it.
• Assuming shorter is always better — but “not unlike” and “similar to” have slightly different meanings. Check meaning, not just length.
