Main Idea, Tone and Author's Purpose

CSAT · Reading Comprehension


Introduction

Main-idea, title, tone and purpose questions ask about the passage as a whole. They are the most common RC question types and, once you have a one-line summary, the quickest to answer.

Key concepts

Main idea and title

The main idea is what the whole passage is about – broad enough to cover every paragraph, narrow enough to be specific. A good title captures the main idea in a few words.

  • Too narrow: covers one example or one paragraph.
  • Too broad: could describe many other passages.
  • Distorted: uses passage words but changes the claim.

Tone and attitude

Tone wordClues in the text
Critical'fails', 'neglects', contrasts between promise and result
Appreciative / laudatorypraise, 'remarkable', 'deserves recognition'
Scepticaldoubt about claims: 'one hopes', 'remains to be seen'
Ironic / sarcasticsaying the opposite of what is meant
Neutral / objectivefacts and process without judgement
Optimistic / pessimisticexpectations about the future
Balancedweighs both sides, conditional conclusions

Author's purpose

Ask *why* the passage was written: to explain, describe, argue, criticise, compare or warn. Look at the verbs: 'shows', 'argues', 'suggests', 'warns'.

The role of a sentence or example

Some questions ask why the author mentions something. Usually it is to support a claim, to illustrate a point, to introduce a contrast or to anticipate an objection.

📐 Formula box
  • Main idea = topic + author's point about it
  • Tone = author's attitude, shown by word choice
  • Purpose = the verb: explain / argue / criticise / warn

Solved examples

Example 1

The new policy, announced with much fanfare, promises universal access within a year. One hopes the funds, the staff and the buildings will appear with equal speed.

The author's tone is best described as:

(a) Sceptical (b) Angry (c) Enthusiastic (d) Neutral

✅ Worked solution
  1. 'One hopes … with equal speed' gently doubts the promise – scepticism, not open anger or praise.

Answer: (a) Sceptical

Example 2

Village health workers walk long distances, keep careful records and are often the first to notice an outbreak. Their contribution deserves far greater recognition and fairer pay.

The author's attitude towards village health workers is:

(a) Indifferent (b) Critical (c) Appreciative (d) Sarcastic

✅ Worked solution
  1. The author praises their work and argues for recognition – appreciative.

Answer: (c) Appreciative

Example 3

This report sets out the rainfall data for the past decade, explains how the averages were calculated and lists the stations used.

The primary purpose of the passage is to:

(a) Criticise weather forecasts (b) Argue for a new policy (c) Tell a story about farmers (d) Describe the data and method of a report

✅ Worked solution
  1. Purely descriptive: what the report contains.

Answer: (d) Describe the data and method of a report

Example 4

Cities often treat street vendors as obstacles. Yet vendors supply cheap food, keep streets lively and safe, and earn livelihoods. Planning for vendors, rather than evicting them, serves everyone better.

Which title best suits the passage?

(a) Evicting Vendors Safely (b) Making Room for Street Vendors (c) The Dangers of Street Food (d) Why Cities Need Malls

✅ Worked solution
  1. The passage argues for planning for vendors – the title must reflect that argument.

Answer: (b) Making Room for Street Vendors

Example 5

Some say technology will solve climate change on its own. Technology matters, but without policies that price pollution and help people adapt, new inventions will spread too slowly.

The author's main point is that:

(a) Policy alone is sufficient (b) Climate change cannot be solved (c) Technology is useless (d) Technology must be supported by policy

✅ Worked solution
  1. 'Technology matters, but without policies …' – both are needed.

Answer: (d) Technology must be supported by policy

Example 6

It is remarkable how many committees have studied this problem, how many reports have recommended the same steps, and how few of those steps have been taken.

The tone of the passage is:

(a) Celebratory (b) Purely factual (c) Ironic and critical (d) Hopeful

✅ Worked solution
  1. Contrasting many reports with few actions is ironic criticism.

Answer: (c) Ironic and critical

Example 7

Traditional water tanks once stored monsoon rain for the dry months. Many have silted up or been built over. Reviving them is cheap compared with new dams and would recharge groundwater.

The author is primarily:

(a) Advocating the revival of traditional tanks (b) Criticising farmers (c) Explaining how silt forms (d) Describing the history of dams

✅ Worked solution
  1. The passage ends with an argument for reviving tanks.

Answer: (a) Advocating the revival of traditional tanks

Example 8

Data can mislead. A district may show high average incomes because a few very rich households lift the average, while most families remain poor. The median often tells a truer story.

The passage mainly warns against:

(a) Studying districts (b) Relying on averages that hide inequality (c) Using the median (d) Collecting income data

✅ Worked solution
  1. The example shows how averages can hide the condition of most families.

Answer: (b) Relying on averages that hide inequality

💡 Shortcut / exam tip
  • Write a six-to-ten-word summary before reading the options.
  • Mild tone words (sceptical, critical) are more often right than extreme ones (furious, contemptuous).
  • The last sentence often states the author's conclusion.
⚠️ Common traps
  • Choosing a title that fits only the first paragraph.
  • Confusing the tone of a quoted person with the author's tone.
  • Picking 'neutral' for a passage that clearly argues a position.
