Paragraph and Sentence Completion

Paragraph & Sentence Completion

Paragraph and Sentence Completion questions test whether a candidate can select the most appropriate word, phrase, clause, sentence, or concluding idea to complete a sentence or paragraph logically and grammatically.

These questions require a combination of:

• grammar
• vocabulary
• comprehension
• contextual understanding
• logical reasoning
• connector usage
• tone recognition
• sentence structure
• coherence
• cause-and-effect understanding

The central principle is:

The correct completion must fit both the language and the logic of the given sentence or paragraph.

A useful approach is:

Read the incomplete text → Identify the missing function → Check grammar → Check context → Check logical flow → Eliminate unsuitable options → Re-read the completed text

Sentence Completion

A Sentence Completion question provides an incomplete sentence and asks the candidate to choose the option that best completes it.

The missing part may be:

• a noun
• a verb
• an adjective
• an adverb
• a phrase
• a clause
• a connector
• a logical conclusion

Grammar-Based Sentence Completion

Example:

If you work hard, you _____ the examination.

A. passed
B. will pass
C. would passed
D. had pass

Correct:

B. will pass

This follows the first conditional pattern:

If + Simple Present → will + V1

Vocabulary-Based Sentence Completion

The committee decided to _____ the matter before taking a final decision.

A. investigate
B. destroy
C. ignore
D. celebrate

Correct:

investigate

The context requires a verb meaning:

examine carefully

Preposition-Based Completion

She is capable _____ handling difficult situations.

A. to
B. at
C. of
D. by

of

The correct expression is:

capable of + noun/V-ing

Conjunction-Based Completion

Although the task was difficult, _____.

A. the team completed it successfully
B. because the team failed
C. but the team completed it
D. so the team refused

Correct:

Cause-and-Effect Completion

The rainfall was extremely low; therefore, _____.

A. reservoirs received less water
B. rainfall increased sharply
C. crops received abundant moisture
D. rivers overflowed immediately

Correct:

A

The completion must logically follow the cause.

A road cannot logically be compared with a year.

Parallel Structure

The programme aims to improve healthcare, strengthen education and _____.

Correct completion:

create employment

The three elements remain parallel:

• improve
• strengthen
• create

Incorrect:

creating employment

because it breaks the pattern.

Sentence Completion with Pronoun Reference

The government introduced a new policy, but it _____.

The pronoun it refers to:

the policy

So the completion must logically describe the policy.

Example:

failed to address several important concerns.

Sentence Completion with Time Sequence

By the time the rescue team arrived, _____.

Correct:

the villagers had already left the area

Reason:

The earlier past action requires:

Past Perfect

Sentence Completion with Modal Meaning

You should _____.

The completion should take V1.

Example:

Sentence Completion with Fixed Expressions

Learn common structures:

• interested in + V-ing
• capable of + V-ing
• responsible for + V-ing
• insist on + V-ing
• prevent from + V-ing
• look forward to + V-ing
• decide to + V1
• refuse to + V1
• had better + V1

Sentence Completion Questions May Test Meaning More Than Grammar

Example:

Despite repeated setbacks, the athlete remained _____.

A. resilient
B. careless
C. indifferent
D. hostile

Correct:

resilient

All options are adjectives, but only one fits the context.

Sentence Completion Strategy

For each incomplete sentence:

• identify the grammatical structure
• identify the relationship between the existing parts
• predict the likely idea
• check the options
• eliminate grammatically incorrect choices
• eliminate logically inconsistent choices
• select the most natural completion

Paragraph Completion

A Paragraph Completion question gives an incomplete paragraph with one sentence or part missing. The candidate must select the sentence that best completes the paragraph.

Unlike Sentence Completion, Paragraph Completion requires understanding the entire flow of ideas.

Understand the Paragraph Structure

A paragraph may follow:

Introduction → Explanation → Example → Conclusion

or:

Problem → Cause → Effect → Solution

or:

Claim → Evidence → Interpretation → Conclusion

The missing sentence must fit its correct role.

Paragraph Completion at the End

Example:

Rapid urbanisation has increased demand for housing, transport and water. In many cities, infrastructure has not expanded at the same rate. As a result, congestion, water shortages and informal settlements have increased. _____

Best completion:

Cities therefore need integrated planning and greater investment in infrastructure.

Why?

The paragraph develops:

growth → pressure → problems → solution

Paragraph Completion in the Middle

Example:

Forests play an important role in regulating climate. _____ They also protect soil from erosion and provide habitats for numerous species.

Possible completion:

They absorb carbon dioxide and store large quantities of carbon.

This sentence supports the ecological role introduced in the first sentence and connects naturally to They also…

Paragraph Completion with Contrast

Digital technology has improved access to information. It has made communication faster and cheaper. _____. Unequal digital access, however, continues to exclude many people.

Suitable missing sentence:

Yet the benefits of digital technology are not distributed equally.

This prepares for the next sentence.

Paragraph Completion with Cause and Effect

The region experienced prolonged drought. Reservoir levels fell sharply and groundwater extraction increased. _____.

Suitable completion:

Consequently, many communities faced severe water shortages.

Paragraph Completion with Example

Many traditional practices contribute to environmental conservation. _____ Such practices demonstrate how local knowledge can support sustainable resource management.

Possible completion:

For example, some communities protect sacred groves from commercial exploitation.

The phrase:

Such practices

refers back to the example.

Paragraph Completion with Explanation

Inflation reduces the purchasing power of money. _____ Therefore, when prices rise faster than incomes, households may be able to buy fewer goods and services.

Best completion:

The same amount of money can then purchase a smaller quantity of goods.

Paragraph Completion with Recommendation

Air pollution increases the risk of respiratory and cardiovascular diseases. Vehicle emissions, construction dust and industrial activities are major contributors. _____

Possible conclusion:

Reducing pollution therefore requires coordinated action across several sectors.

Paragraph Completion with Summary

Renewable energy can reduce emissions, diversify energy sources and improve energy security. However, its expansion requires investment in grids and storage. _____

Suitable completion:

Thus, the energy transition requires both renewable generation and supporting infrastructure.

Use Pronoun References

Suppose the option begins:

These measures can significantly improve urban resilience.

Then the previous sentences should mention several measures.

If no such measures have been introduced, the option is unlikely to fit.

Use Connector Logic

An option beginning:

However

must contrast with the previous idea.

An option beginning:

Therefore

must follow a cause or argument that produces a result.

An option beginning:

For example

must illustrate a preceding general statement.

Use Topic Continuity

A paragraph about:

groundwater depletion

should not suddenly conclude with:

Therefore, space exploration must receive more funding.

Even if grammatically correct, it is contextually irrelevant.

Avoid Repetition

The best completion should add something useful.

Poor completion:

Urban flooding is a serious problem in many cities.
Urban flooding is a serious problem.

This merely repeats the previous idea.

Better:

Improved drainage, wetland protection and land-use planning can help reduce the risk.

Paragraph Completion Example

Read:

Education has an important role in social mobility. It can improve employment opportunities and help individuals acquire knowledge and skills. However, unequal access to quality education can reinforce existing social divisions. _____

A. Therefore, improving educational access is essential for creating more equal opportunities.
B. Schools should remain closed permanently.
C. Employment has no connection with education.
D. Inequality is always impossible to reduce.

Correct:

A

The paragraph moves:

importance → benefit → problem → conclusion

Sentence Starters

A Sentence Starter is the beginning portion of a sentence. The candidate must choose the completion that fits its grammar, meaning, and logical direction.

Sentence starters often provide strong clues.

Although

Although _____, the team completed the project on time.

The missing part should normally contain a fact that contrasts with successful completion.

Suitable:

Although it faced several difficulties, the team completed the project on time.

Because

Because _____, the match was postponed.

The missing part must provide a cause.

Example:

Because heavy rain continued throughout the afternoon, the match was postponed.

Unless

Unless _____, the problem will continue.

Despite

Despite _____, she completed the journey.

After despite, normally use:

• noun
• noun phrase
• V-ing

Correct:

Despite the heavy rain…

Despite feeling tired…

Not:

Despite she was tired… in standard usage.

In Spite Of

Pattern:

In spite of + noun/V-ing

Example:

In spite of facing difficulties, he continued his studies.

In Order To

Pattern:

in order to + V1

Example:

In order to reduce pollution, the city expanded public transport.

So That

Pattern:

so that + clause

Example:

Second conditional.

If they had left earlier, they would have arrived on time.

Third conditional.

When

Example:

For future time:

I will inform you when the results are announced.

Not usually:

when the results will be announced

in this type of future time clause.

While

May indicate:

simultaneous action

Example:

While she was studying, her brother was watching television.

It may also show contrast:

While the first proposal is inexpensive, the second is more effective.

Since

May mean:

from a point in time

or:

because

Example:

Since 2020, the city has expanded rapidly.

Example:

Since the road was blocked, we took another route.

Context determines the meaning.

Given That

Introduces a fact or condition.

Example:

Given that rainfall has declined, water conservation has become increasingly important.

As a Result

Requires an earlier cause.

Example:

The rainfall failed for several weeks. As a result, reservoir levels declined.

On the Other Hand

Introduces contrast or another perspective.

Example:

Private vehicles offer flexibility. On the other hand, public transport can move large numbers of people more efficiently.

Not Only

Pattern:

not only…but also

Example:

The programme not only created employment but also improved local infrastructure.

No Sooner

Pattern:

No sooner had + subject + V3 + than…

Example:

No sooner had the meeting begun than the electricity failed.

Hardly / Scarcely

Pattern:

Hardly/Scarcely had + subject + V3 + when…

Example:

Hardly had he arrived when it started raining.

Common Traps in Sentence and Paragraph Completion

Trap 1: Grammatically Correct but Illogical

Sentence:

The city received exceptionally heavy rainfall; therefore, _____.

Option:

water scarcity increased because no rain fell

Grammatically possible, logically contradictory.

Trap 2: Correct Idea but Wrong Grammar

She is capable _____ the task.

Correct idea may involve performing it, but the grammar must be:

capable of performing

Trap 3: Repetition without Progress

A completion should usually develop the idea.

Weak:

Pollution is a serious problem. Pollution is serious.

Better:

Reducing it requires action from governments, industries and citizens.

Trap 4: Wrong Connector

Cause:

Rainfall was inadequate.

Result:

Crop production declined.

Correct connector:

therefore

Not:

however

unless the writer intends a contrast.

Trap 5: Extreme Conclusion

Given:

Some students found the new method difficult.

Wrong:

Therefore, the method is useless for everyone.

The conclusion exceeds the evidence.

Trap 6: New Unrelated Idea

A paragraph about:

soil erosion

should not conclude with an unrelated statement about:

international trade.

Trap 7: Pronoun without Antecedent

Option:

These measures were effective.

If the paragraph has not introduced any measures, this option cannot fit naturally.

Trap 8: Change of Tone

If a paragraph is balanced and analytical, a highly emotional conclusion may be inappropriate.

Trap 9: Wrong Time Sequence

Sentence:

By the time the police arrived…

The completion usually describes something that had already occurred:

the thieves had escaped

not:

the thieves will escape

Trap 10: Half-Correct Option

An option may begin logically but end with an unsupported claim.

Always evaluate the entire option.

How to Solve Sentence Completion Quickly

Use:

Grammar → Meaning → Logic → Natural Usage

Ask:

• What grammatical form is required?
• What idea is being developed?
• Does the completion match the connector?
• Is the resulting sentence natural?
• Does it preserve the intended meaning?

How to Solve Paragraph Completion Quickly

Use:

Theme → Previous Sentence → Missing Function → Next Sentence

Determine whether the missing sentence should:

• introduce
• explain
• contrast
• give an example
• show a result
• provide a solution
• conclude

Position of the Blank Matters

If the blank is at the beginning, it may need to introduce the topic.

If it is in the middle, it often connects two ideas.

If it is at the end, it often:

• concludes
• summarises
• recommends
• predicts
• gives a result

Before-and-After Technique

For a middle blank:

Sentence before → Blank → Sentence after

The correct choice should make both connections natural.

Example:

Technology has increased access to information. [BLANK] However, misinformation can also spread rapidly online.

The blank should probably develop the benefits before the contrast.

Possible:

Digital platforms allow information to reach large audiences almost instantly.

Then:

However…

introduces the negative side.

Quick Revision Table

Important Starter Patterns

Key Points to Remember

• Sentence and Paragraph Completion questions test both grammar and logic.
• Do not choose an option merely because it is grammatically correct.
• Do not choose an option merely because it contains words related to the topic.

For Sentence Completion:

• identify the grammatical structure
• predict the missing meaning
• check collocation
• check logical consistency

For Paragraph Completion:

• identify the theme
• understand paragraph structure
• read the sentence before the blank
• read the sentence after the blank
• determine the missing function

Remember connector meanings:

• although/however → contrast
• because → cause
• therefore/consequently → result
• moreover → addition
• for example → illustration
• unless → negative condition
• in order to → purpose

Watch for grammar patterns:

• modal + V1
• have/has/had + V3
• preposition + noun/V-ing
• in order to + V1
• despite + noun/V-ing
• although + clause

Avoid options that are:

• too extreme
• unrelated
• repetitive
• grammatically incorrect
• logically contradictory
• inconsistent with the tone
• dependent on information not provided

The strongest completion is the one that creates the greatest grammatical accuracy, contextual relevance, logical continuity, and natural flow.

A useful final formula is:

Sentence Completion = Grammar + Meaning + Logic

Paragraph Completion = Context + Coherence + Continuity

When these elements are checked systematically, Sentence and Paragraph Completion questions become far more predictable and easier to solve accurately.
