MockoMany TEF reading questions ask for the main idea of a short text: an ad, a notice, an email, a short article. It sounds easy, but the options are designed so that a true detail from the text feels like the right answer. This lesson teaches you to separate the central message from the supporting details, and to choose the option that covers the whole text rather than just one line of it.
What you’ll learn
- Tell the difference between the main idea and a supporting detail
- Find the main idea quickly using the title, first line and repeated words
- Test each option against the whole text, not a single sentence
- Recognise the three classic wrong-answer types in main-idea questions
Main idea versus detail
The main idea is the one sentence that the whole text is built around, what the author would say if you asked "What is this about, in a nutshell?" A detail is a fact, example or reason that supports the main idea. Both are true and both come from the text, but only the main idea answers the question.
« Notre bibliothèque ouvre désormais le dimanche. Vous pourrez emprunter des livres, utiliser les ordinateurs et participer à des ateliers de lecture. »
"Our library is now open on Sundays. You can borrow books, use the computers and join reading workshops."
- Main idea: the library now opens on Sundays.
- Details: borrowing books, using computers, reading workshops.
- A question on the main idea wants the opening hours, not the list of activities.
Where the main idea hides
You rarely need to read every word to find the main idea. Scan these high-value spots first.
- 1The title or subject line, often the main idea in compressed form.
- 2The first sentence, since French texts frequently state the point up front.
- 3Repeated words or ideas, because what comes back is what matters.
- 4The last sentence, where a conclusion or call to action often restates the point.
The "covers the whole text" test
Once you have a candidate answer, check it against the entire text with one question: does this option summarise everything, or only one part? The right answer is broad enough to include the details. A wrong answer is usually too narrow.
Quick self-check
- Too narrow? It only matches one sentence, so it is a detail, not the main idea.
- Too broad or off-topic? It mentions things the text never says, so eliminate it.
- Just right? It could be the title of the text, so it is likely the answer.
The three classic distractors
What the wrong options usually do
- The detail trap: a true fact from the text, but only a small part of it.
- The word-match trap: it reuses a striking word from the text in a false statement.
- The outside-knowledge trap: plausible and true in general, but not what this text says.
Notice that all three can feel correct. That is the point. Always come back to what the text actually states, and choose the option that fits the text as a whole.
How to practise this
How to train this at home
- Read a short French article and write its main idea in one sentence, in your own words.
- Then list two details. Practising the split trains your eye for the difference.
- Cover the text and check: does your one-sentence summary still make sense alone?
- Time yourself, aiming to find the main idea of a short notice in under 30 seconds.
Key takeaways
- The main idea is what the whole text is about; a detail supports it.
- Scan the title, first line, repeated words and last line to find it fast.
- Pick the option that covers the entire text, not just one sentence.
- Watch for detail, word-match and outside-knowledge distractors.
