Paragraph Summary, Odd Sentence & Completion
✨ Login to trackOdd sentence out
✨ Login to trackYou get four or five sentences that mostly build one theme, and one sentence that does not belong. The odd sentence usually shares some words with the theme — that is the trap. Test what the sentences do, not what they mention: the theme is an idea (a cause, a process, a place, an event), and four sentences push that idea forward while one quietly serves a different idea.
The theme is a job, not a topic
Four sentences work together like a small team: each one advances the same job. The odd sentence is the one doing a different job while wearing similar clothes. So after your first read, complete this line: "All the sentences except one are about…" — and finish it with a verb-ish idea (protecting coasts, cutting costs, explaining a rule), not just a noun (cyclones, money, law).
Four common intruder types
- Topic-mate, different job — talks about the same subject (e.g. the same sport, the same chemical) but serves another purpose: a profit line inside a logistics paragraph.
- Scope shift — national ↔ local, general rule ↔ one celebrity example, cause ↔ business result.
- Time or place shift — the paragraph sits in one period/region; the intruder floats elsewhere with no bridging words.
- Direction shift — four sentences build one chain (problem → cause → fix); the intruder starts a different chain that goes nowhere.
A reliable method
- Read all five sentences once for the flavour, then name the theme's job in 3 words.
- Underline the subject + verb of each sentence (what is each one doing?).
- The sentence whose doing does not serve the named job is your answer — even if it shares the most vocabulary with the others.
- Final check: remove the suspect and see whether the rest flow as one clean paragraph. If the remaining four still feel broken, you removed the wrong one.
A full walk-through
Sentences: (A) Cement demand tracks infrastructure spending closely. (B) Housing starts lifted cement sales last quarter. (C) The festival season usually sees a paint sales spike. (D) Government road projects added bulk orders for cement makers. (E) Cement prices firmed up in the southern plants.
- Theme's job: what is driving cement demand and prices — A, B, D, E all serve it.
- C talks about paint, a neighbouring building-material — the topic-mate trap. Shared folder (home improvement), different job. C is the odd sentence.
Exam-room method (60–90 seconds)
- Read the five sentences once at speed — do not solve yet.
- Write the theme's job in three words in your head.
- Mentally strike the sentence whose subject+verb does not serve that job.
- Check the survivor test: the remaining four must read as one paragraph with no gap. If two candidates feel odd, prefer the one whose removal heals the paragraph — relevance always beats rarity.
Question types you will see
Each type: how to recognise it, the method step by step, and one question to try.
Topic-mate intruder
All sentences mention the same broad subject, but one serves a clearly different purpose.
Name the theme's job.
Mark each sentence's purpose.
Pick the sentence serving a different purpose.
Exam writers reuse the topic words across all five sentences to defeat keyword spotting.
A–D describe how UPI made small-shop payments instant; E says "Smartphone prices fell sharply last year."
Show solutionHide solution
E touches the same digital ecosystem but is about hardware prices, not payment behaviour — odd one.
Scope shift
Four sentences stay at one level (national programme); one drops to a personal anecdote or rises to a global claim.
Fix the paragraph's level.
Flag the sentence at a different level.
Level breaks are subtler than topic breaks and test careful reading.
A–D on India's national rooftop-solar subsidy rules; E on one homeowner's electricity bill.
Show solutionHide solution
E is a single-household story inside a policy paragraph — odd one.
Time or place shift
One sentence sits in another era or region with no connector to the rest.
Note the time/place anchor of the majority.
Pick the floating sentence.
Anchors are easy for writers to control and easy for readers to miss under time pressure.
A–D on this winter's fog delays in north India; E on the 1905 famine.
Show solutionHide solution
E's anchor is a different century — odd one.
Direction shift (broken chain)
Four sentences form a problem → cause → fix chain; one starts a chain that goes nowhere.
Trace the chain.
Find the sentence nothing follows from.
Coherence questions test whether you track an argument's flow, not its vocabulary.
A: A lake filled with weeds. B: Sewage fed the weeds. C: The city diverted the sewage. D: The weeds died back within a year. E: Weeds make good compost.
Show solutionHide solution
A–D form one story; E is a true fact that interrupts the chain — odd one.
Shortcuts that save time
After reading all sentences, say the theme in three words (e.g. "mangroves protect coasts"). Any sentence that is not doing exactly that job is the odd one.
Four sentences on mangroves blocking cyclone waves; one sentence names a cyclone's wind speed.
Show solutionHide solution
The wind-speed sentence mentions the same cyclone but is about meteorology, not protection — odd one out.
The intruder often stays on-topic but shifts level: the paragraph is about a national programme and the odd sentence talks about one person's profit, or vice versa.
Four sentences on a vaccination drive's logistics; one says "Vaccine makers posted record profits."
Show solutionHide solution
Same subject family, different scope (business results vs. drive logistics) — odd one.
If four sentences live in one time period or one place and one floats to another era or region for no reason, that one is out.
Four sentences on this year's monsoon onset; one describes a 19th-century famine.
Show solutionHide solution
The historical sentence is off the time anchor — odd one.
Mistakes to avoid
Where most students lose marks on this subtopic.
Picking the sentence with the rarest word instead of the sentence that breaks the theme's job.
Keeping a sentence that merely mentions the theme's topic but actually develops a different point.
Choosing an odd sentence that is simply harder to understand — difficulty is not the test; relevance is.
Quick revision
Read this the night before the exam.
Theme = a job (verb idea), not a topic (noun).
Shared vocabulary is the trap; shared purpose is the test.
Intruders shift scope, time, place, or direction.
Remove the suspect — the rest must read as one clean paragraph.
