5.5 Jumbled Sentences & Sentence Improvement

Key Takeaways

  • Jumbled sentences and Sentence correction are separate bullets of the CIL Paper-I English syllabus, the first testing coherence and the second testing grammar.
  • In a jumbled-sentence item the opening part almost never begins with a pronoun, a conjunction or a definite article referring to something not yet introduced.
  • Mandatory pairs — two parts that must sit together because of a pronoun, an article or a connector — are the fastest route to eliminating options.
  • In sentence improvement, the correct answer changes only what is grammatically wrong; an option that rewrites the whole sentence in acceptable but different English is usually a distractor.

Part 1: Jumbled Sentences and Para Jumbles

A jumbled item gives the parts of a sentence, or the sentences of a paragraph, out of order and asks for the correct sequence. The efficient approach never reconstructs the whole sequence from scratch; it identifies one or two certainties and eliminates options that violate them.

Step 1: Find the opener

The opening part is usually identifiable by exclusion. An opener almost never:

  • begins with a pronounit, they, this, these, he, she — because the referent has not yet been introduced;
  • begins with a conjunction or connectorbut, however, therefore, moreover, hence, also;
  • begins with the attached to a noun not yet mentioned;
  • begins with a relative clausewhich, who, whose.

An opener typically introduces the subject with an indefinite article or a proper noun, and states the general idea before any qualification.

Step 2: Find mandatory pairs

A mandatory pair is two parts that must be adjacent and in a fixed order. The signals:

SignalWhat it forces
A pronounMust follow the part naming its referent
The + nounMust follow the part where that noun first appeared with a or an
This, these, suchMust follow the idea being pointed back to
Correlatives: not only ... but also; either ... or; neither ... norFixed order, usually adjacent
Firstly ... secondly; on the one hand ... on the otherFixed order
However, but, neverthelessMust follow the statement being contrasted

Once a mandatory pair is fixed, scan the four options and strike out every one that separates the pair or reverses it. This single step often leaves only one option standing.

Step 3: Apply ordering logic

If pairs do not settle it, the sequence usually follows one of these patterns:

  • Chronological — events in the order they happened; watch for dates and time markers.
  • General to specific — a broad statement, then detail, then example.
  • Problem to solution — the difficulty stated, then the remedy.
  • Cause to effect — the cause precedes therefore or as a result.

Worked example

A. It was subsequently extended to the Jharia field. B. Commercial coal mining in India began at Raniganj in 1774. C. The activity was initially confined to shallow workings near the outcrop. D. These early operations used simple manual methods.

B must open: it is the only part with a proper noun and no back-reference, while A begins with It, C with The activity and D with These. D contains These early operations, which points back to the workings described in C, so C must precede D. A begins with It was subsequently extended, marking a later stage, so it comes last. The order is B, C, D, A.

Notice that identifying the opener and the single mandatory pair C-D was enough; the rest followed.

Part 2: Sentence Improvement and Correction

A sentence-improvement item underlines part of a sentence and asks which replacement is best, with no improvement usually among the options. The governing principle:

Change only what is actually wrong. An option that produces different but equally acceptable English is a distractor, not an improvement.

The error checklist

Run the underlined portion against these in order.

Error typeWhat to check
Subject-verb agreementIgnore intervening phrases; find the true subject
TenseConsistency with the rest of the sentence; correct sequence in reported speech
PronounAgreement in number and person; unambiguous referent
ParallelismItems in a list must share grammatical form
Modifier placementA participial opener must attach to the subject that follows
PrepositionFixed collocations
ArticlePresence, absence, and a versus an by sound
ComparisonComparative for two, superlative for more than two; like versus as
RedundancyReturn back, repeat again, more better, cent per cent
ConditionalIf I were, not if I was, for hypothetical conditions

High-frequency traps

Agreement across a phrase. The set of drawings is ready, not are — the subject is set, not drawings.

Either or neither. These take singular verbs: Neither of the pumps is operating.

Collective nouns. In Indian usage as in British usage, a collective noun takes a singular verb when the group acts as a unit: The committee has approved the proposal.

Dangling modifiers. Having inspected the belt, the fault was obvious is wrong, because the fault did not inspect the belt. Correct it to Having inspected the belt, the engineer found the fault obvious.

Parallelism. The trainee is responsible for planning, scheduling and to monitor the work breaks the pattern; it should be monitoring.

Double comparatives. More easier and most fastest are always wrong.

Since and for. Since takes a point in time — since 2015; for takes a duration — for eight years.

One of the. One of the best engineers who have worked here — the relative clause attaches to engineers, which is plural.

Worked examples

Each of the four subsidiaries have submitted their report.

The subject is Each, which is singular, so the verb must be has, and the pronoun should be its. Corrected: Each of the four subsidiaries has submitted its report.

The output of the mine is higher than last year.

This compares an output with a year. Corrected: higher than that of last year, or higher than it was last year. Faulty comparison is one of the most reliably tested errors.

He is senior than me.

Words of Latin origin ending in -or — senior, junior, prior, superior, inferior, preferable — take to, not than. Corrected: He is senior to me.

Method Summary

For jumbles, find the opener, find one mandatory pair, and eliminate. For improvement, run the checklist and prefer the minimal correction. Both formats reward elimination over construction, and both are quick enough that they should never be the items that run you out of time on Paper-I.
