Learning Outcomes
- Identify and distinguish simple, compound, complex, and compound-complex sentences.
- Detect and correct common GMAT sentence errors: run-ons, fragments, misplaced modifiers, and parallelism failures.
- Apply strategies for clarity, concision, and variety under timed conditions.
- Translate key concepts into Bengali for bilingual reinforcement.
Conceptual Explanation
Core definitions
A sentence expresses a complete thought and is built from clauses: independent (can stand alone) and dependent (cannot stand alone). Effective GMAT sentence correction requires rapid parsing of clause roles, verb agreement, pronoun reference, and modifier placement.
Sentence types — quick table
| Type | Structure | Example | Why it matters |
|---|---|---|---|
| Simple | One independent clause | The cat sleeps. | Clarity; often used to fix awkward constructions. |
| Compound | Two independent clauses + coordinating conjunction | The cat sleeps, and the dog barks. | Combines related ideas; watch for comma + conjunction and independent punctuation. |
| Complex | Independent + one/more dependent clauses | Although the cat sleeps, the dog barks. | Introduces subordination; check subject-verb agreement in main clause. |
| Compound-complex | At least two independents + one/more dependent | Although the cat sleeps, the dog barks, and the bird sings. | Most advanced; common GMAT trap for misplaced modifiers and parallelism. |
Common GMAT traps
- Run-on (comma splice) — two independents not properly joined.
- Fragment — missing subject or verb, or dependent clause standing alone.
- Misplaced modifier — modifier not adjacent to the word it describes.
- Non-parallel lists — inconsistent grammatical form in series.
Bilingual (EN → বাংলা)
Key terms
- Sentence — বাক্য
- Independent clause — স্বাধীন কর্তন (স্বতন্ত্র বাক্যাংশ)
- Dependent clause — অনুসরিত কর্তন (আধারিত বাক্যাংশ)
- Modifier — সংশোধক
- Parallelism — সমান্তরালতা
Short concept translations
Clarity (স্পষ্টতা): বাক্যটি যেন বিভ্রান্তি তৈরি না করে।
Conciseness (সংক্ষেপ): অতিরিক্ত শব্দ বাদ দিন — "He succeeded because he worked hard."
Misplaced modifier example: "She almost drove her kids..." → স্পষ্ট: "She drove her kids almost every day."
Important Notes
- On the GMAT, prefer choices that improve clarity and concision while preserving original intent.
- Always check pronoun reference, verb tense/number, modifier placement, and parallel structure.
- When in doubt, break complex choices into clauses and test each clause independently.
- Time management: spend ~1–1.5 minutes per sentence correction item; eliminate clearly wrong options fast.
Exercises
True / False
- “A compound sentence may contain subordinating clauses.”
Answer
True — a compound sentence can include subordinating clauses; then it becomes compound-complex.
- “Removing a modifier always makes the sentence clearer.”
Answer
False — removing necessary modifiers can create ambiguity; only remove unnecessary words.
- “Pronoun-antecedent agreement is irrelevant in sentence correction.”
Answer
False — it is essential; mismatched number or unclear antecedent cause errors.
Fill in the Blanks
- Complete: “______ the rain, we proceeded with the picnic.”
Answer
Although the rain, we proceeded with the picnic. ⇒ Correct: "Despite the rain, we proceeded..." or "Although it rained, we proceeded..." (preferred: "Despite the rain, ...")
- Fix fragment: “Because the test was hard.” → Complete the thought.
Answer
Because the test was hard, many students studied all night.
- Parallelize: “She likes to swim, running, and to bike.” → Correct version.
Answer
She likes swimming, running, and biking. (Alternatively: To swim, to run, and to bike.)
Multiple Choice (MCQ)
-
Choose the best revision: “The manager, along with her team, are planning the event.”
- The manager, along with her team, are planning the event.
- The manager, along with her team, is planning the event.
- The manager along with her team are planning the event.
- The manager with her team planning the event.
Answer
B — “is” agrees with the subject "The manager" (the phrase "along with her team" is parenthetical).
-
Identify the misplaced modifier: “Walking to class, the rain drenched Maria.”
Answer
Misplaced modifier — it incorrectly modifies "the rain." Correct: "Walking to class, Maria was drenched by the rain." or "As Maria was walking to class, the rain drenched her."
-
Which choice is most concise and preserves meaning? Original: “The reason why he succeeded is because he worked hard.”
- The reason why he succeeded is because he worked hard.
- He succeeded because he worked hard.
- It is because he worked hard that the reason he succeeded exists.
- Because of hard work he succeeded was the reason.
Answer
B — concise and clear: “He succeeded because he worked hard.”
Matching
Match error type → example number (A–D)
| Error type | Example |
|---|---|
| 1. Run-on / comma splice | A. She loves coffee, she drinks it every morning. |
| 2. Fragment | B. Because the project was late. |
| 3. Misplaced modifier | C. Almost drove her kids to school every day. |
| 4. Parallelism | D. He likes hiking, to swim, and biking. |
Answer
1 → A (run-on); 2 → B (fragment); 3 → C (misplaced modifier / ambiguous "almost"); 4 → D (non-parallel list — fix to "hiking, swimming, and biking").
Descriptive
Explain briefly (1–2 sentences): Why is parallelism important in lists on the GMAT?
Answer
Parallelism ensures grammatical consistency and clarity; nonparallel lists create awkwardness and often indicate an incorrect answer choice because they violate grammatical symmetry.
Creative
Rewrite the following into a clear compound-complex sentence: “He studied for months. He failed twice. He still applied again.”
Answer
Although he studied for months and failed twice, he still applied again, demonstrating persistence.
Activities
- Timed sentence-correction drills: 10 items × 10 minutes; review with explanations.
- Peer editing: exchange five sentences and identify errors + rewrite for clarity.
- Recasting practice: take complex official questions and rewrite in two simpler forms.
Vocabulary
- Subordinate / dependent clause — পূরক- or নির্ভরশীল কর্তন
- Parallelism — সমান্তরালতা
- Modifier — সংশোধক
- Antecedent — পূর্বপ্রচলিত (প্রোনাউনের পূর্ববর্তী নাম)
Homework
- Complete 20 official GMAT Sentence Correction problems. For each: identify error type and rewrite the sentence. Use timed 1.5 minutes per question.
- Write 5 compound-complex sentences on any academic topic; exchange with a peer for feedback.
Answer / model
Model for item 1: After solving, list error types (e.g., subject-verb agreement, modifier placement) and supply corrected sentence. For item 2: Example — "Although researchers found promising trends, the sample size was small, and they recommended further studies to confirm the results."
Practice Task
Daily micro-task (10 minutes): pick one paragraph from an article; identify all sentence types, mark any errors, and rewrite one sentence to improve clarity and concision.
Answer / sample
Sample rewrite: Original — "The study, which was conducted over several months, the results were inconclusive." Correct — "The study, conducted over several months, produced inconclusive results."
