Before you start
Compare The more we revise, the clearer it becomes with It contains no more than six pages. What relationships are expressed?
Useful background: Comparatives; B1 changing situations and measured differences; basic quantities.
Link two changing quantities or qualities
The + comparative can introduce each side of a linked change. The relationship may be positive or negative; keep the direction clear. Such wording does not by itself prove a scientific cause or supply a numerical formula.
The more we simplify the instructions, the easier they become to follow.
The longer we wait, the less time we have for questions.
State a limit carefully
Not more than commonly states an upper bound. No more than can also express an upper bound and often presents the amount as small or limited in context. Neither expression alone forces an exact number.
The summary must be not more than six pages long.
The whole summary takes no more than six pages.
Keep evaluation separate from measurement
No less than often adds emphasis to a surprisingly large amount; not less than states a lower bound more neutrally in many contexts. Context controls the rhetorical effect. Preserve the actual inequality when paraphrasing.
The review took no less than three hours.
Allow not less than twenty minutes for the discussion.
A minimum includes its boundary
At least twenty minutes is a neutral paraphrase; fifteen does not meet this minimum.
This does not require every discussion to finish at exactly twenty minutes.
Guided practice
Say or write your answer first. Compare the meaning and form; the model is one possible answer.
1. Link the changes: We wait longer. We have less time left.
Compare a model and explanation
The longer we wait, the less time we have left.
The two comparatives show opposite directions of change.
2. Complete with fewer or less: The clearer the form, the ___ questions people ask.
Compare a model and explanation
fewer
Questions is a plural countable noun.
3. Paraphrase not more than six pages using at most.
Compare a model and explanation
At most six pages.
Both expressions state an upper bound including six.
4. Does no more than six pages require exactly six pages? Explain.
Compare a model and explanation
No. It sets an upper bound; the actual length may be shorter.
Evaluative smallness does not turn an inequality into equality.
5. Paraphrase not less than twenty minutes using at least.
Compare a model and explanation
At least twenty minutes.
Twenty is a lower bound, not a maximum.
6. Read the review note. Explain why the four-page summary complies with the page limit.
Compare a model and explanation
Four is below the maximum of six, so it fits the limit.
Compliance depends on the inequality, not on reaching the maximum.
7. Explain why The more examples we add, the clearer the text becomes does not by itself establish an experimentally proven cause.
Compare a model and explanation
It states a relationship in the speaker’s account, but supplies no study, measurement or independent evidence.
Grammar can express a claimed relationship without proving it.
8. Rephrase The review took no less than three hours neutrally while preserving the minimum.
Compare a model and explanation
The review took at least three hours.
The lower bound is kept while the marked evaluative emphasis is reduced.
A short conversation
Listen first if you can, then open the transcript when useful.
Open the conversation transcript
A: The longer the introduction gets, the less room we have for the examples.
B: Then let’s shorten it. The summary must be no more than six pages.
A: The current version is four pages, so we’re within the limit.
B: Good. Allow at least twenty minutes for discussion. The clearer the examples are, the more useful that time should be.
Listening checks
Listen to each extract or open its transcript. These three questions have their own score.

Speaking task 1
Explain the review note to a colleague, including one linked change and both a maximum and a minimum.
Reveal a possible response
The longer the introduction gets, the less room we have for examples. The summary can be at most six pages, and the current four-page version fits. We should allow at least twenty minutes for discussion.
Success check: Keep directions, bounds and actual values distinct.
Speaking task 2
Create two descriptions of the same review duration, one neutral and one expressing surprise.
Reveal a possible response
The review took at least three hours. It took no less than three hours, although we had expected a brief check.
Success check: Use context to establish the evaluative effect rather than asserting it is automatic.
Speaking task 3
Critique a misleading paraphrase that turns a range into an exact value.
Reveal a possible response
Saying the document is exactly six pages misreports a six-page maximum. The limit allows shorter documents, and we would need separate evidence for an exact count.
Success check: Explain the specific change in meaning and repair it.
