Before you start
Give a clearly approximate attendance figure.
See one possible response
About fifty people attended.
You edit a fictional account of a long costume-making session and attendance at a local performance.
What you will practise
- Interpret and use an emphatic quantified phrase without inventing exact measurement.
- Distinguish approximate quantity from a subset of an identified group.
- Recast a marked quantity for a different audience without increasing certainty.
Respond before revealing. Preserve participant roles, source limits and register; justify a valid alternative where the context permits it.
A good three hours
In a good + number + plural unit, good emphasises a substantial amount, often a full amount or more: It took a good three hours. This is not the ordinary a + singular noun pattern. It does not supply stopwatch precision.
The final fitting took a good three hours.
We walked a good five kilometres before finding the entrance.
Some fifty people
Some before a number can mean approximately, especially in more formal reporting: Some fifty people attended. Contrast some of the fifty people, which selects a subset of a known group. Stress and context matter; the written pattern alone must be read as a whole.
Some fifty visitors saw the rehearsal.
Some of the fifty visitors stayed for questions.
Keep neutral and marked versions distinct
About fifty states an estimate; a good fifty can emphasise the amount as substantial. An editor should preserve both the numerical uncertainty and the evaluative force when they matter. Use an exact figure only when the source provides one.
It took about three hours, which felt like a long session.
Approximately fifty people attended; the exact count was not recorded.
Keep the estimate and the evaluation
Approximate length, with no exact timing.
The speaker presents the amount as considerable.
Guided practice
Say or write your answer first. Then compare the meaning and grammar with the model.
1. The repair took a good four hours. Is good judging the repair’s quality?
Compare a model and explanation
No.
It evaluates the substantial amount of time in this phrase.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
2. Some forty guests arrived. Some of the forty guests arrived early. What changes?
Compare a model and explanation
The first estimates a total; the second identifies a subset of a known forty.
The added of the changes the reference structure.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
3. Some sixty people attended.
Compare a model and explanation
Approximately sixty people attended.
This retains the approximation in a neutral form.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
4. A good three hours becomes exactly three hours and zero minutes. Is that faithful?
Compare a model and explanation
No.
The original is emphatic, not a precise timing record.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
5. Describe a substantial distance using a good + five + kilometres.
Compare a model and explanation
We walked a good five kilometres.
This marked quantified pattern allows the plural unit after a good.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
6. A good fifty people and about fifty people can refer to similar numbers. What extra effect can good add?
Compare a model and explanation
It can present the amount as substantial.
The evaluative emphasis is not a new exact count.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
7. The source says some thirty helpers, but a chart demands an exact total.
Compare a model and explanation
The exact total is not supplied; label the figure approximately thirty.
Do not fabricate precision to fill a reporting format.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
8. A rehearsal lasted a substantial three hours. Attendance was roughly fifty, and ten stayed after. Give a careful account.
Compare a model and explanation
The rehearsal lasted a good three hours. Some fifty people attended, and ten stayed afterwards.
The measured or stipulated ten is not confused with the approximate attendance.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
A short conversation
Listen to the exchange, then take one role. The speaker labels identify roles; do not narrate them.
Open the conversation transcript
Writer: I’ve written that the rehearsal took exactly three hours and fifty people attended.
Editor: The notes say a good three hours and some fifty people. Neither is an exact measurement.
Writer: So I should keep the estimates and the sense that it was a long session.
Editor: Yes. Don’t turn an emphatic account into a precise attendance record.
Listening checks
Listen to each extract, then choose the best answer. These three questions have their own score.
Answer key with explanations
What is conveyed?
A substantial, not precisely measured period.: The speaker explicitly distinguishes emphasis from timing.
Compare all choices
- A substantial, not precisely measured period.: The speaker explicitly distinguishes emphasis from timing.
- Exactly one hundred and eighty minutes.: Precise timing is denied.
- A positive evaluation of the clothes only.: Good modifies the quantity of time here.
What does some fifty mean here?
Approximately fifty.: The lack of an exact count confirms approximation.
Compare all choices
- Exactly fifty without uncertainty.: That exceeds the source.
- Approximately fifty.: The lack of an exact count confirms approximation.
- A subset of an already counted group of fifty.: There is no of the subset phrase.
What group is described?
A subset of a known group of fifty volunteers.: Of the identifies the larger group.
Compare all choices
- Approximately fifty additional volunteers.: The phrase does not introduce an extra estimated group.
- Every volunteer necessarily.: Some does not establish that all stayed.
- A subset of a known group of fifty volunteers.: Of the identifies the larger group.

Answer key with explanations
In a good three hours, good primarily contributes ___.
emphasis on a substantial amount: It does not merely describe the quality of the hours.
Compare all choices
- proof of exact stopwatch timing: The construction does not provide that precision.
- a claim that the event was enjoyable: A long duration need not be enjoyable.
- emphasis on a substantial amount: It does not merely describe the quality of the hours.
Which means approximately sixty attendees?
Some sixty attendees.: Some before a number can signal an estimate.
Compare all choices
- Some sixty attendees.: Some before a number can signal an estimate.
- Each of the sixty attendees.: This distributes a claim across the identified group.
- Some of the sixty attendees.: This selects a subset of a known group.
Which preserves an approximate source?
About fifty people attended.: Approximation remains explicit.
Compare all choices
- Exactly fifty attended, with no uncertainty.: This adds precision.
- About fifty people attended.: Approximation remains explicit.
- Fifty more attended than expected.: This invents a comparison.
Does a good five kilometres guarantee a precise endpoint at five kilometres?
No.: The expression is emphatic and commonly approximate.
Compare all choices
- Yes, but only in British English.: Regional variation does not create a measurement guarantee.
- Yes, down to the metre.: That precision is not encoded.
- No.: The expression is emphatic and commonly approximate.
What does some of the fifty people require?
An identified larger group of fifty.: The phrase refers to a subset of that group.
Compare all choices
- An identified larger group of fifty.: The phrase refers to a subset of that group.
- An exact claim that all fifty acted.: Some does not establish all.
- A second group of fifty additional people.: No extra group is introduced.
Which noun form fits the target pattern?
a good three hours: The quantified phrase uses the plural unit.
Compare all choices
- a good of three hours: Of is not part of this construction.
- a good three hours: The quantified phrase uses the plural unit.
- a good three hour: This is not the duration noun phrase target.
An editor removes good and writes approximately three hours. What may be lost?
The speaker’s emphasis on the amount as substantial.: The numerical estimate can remain while evaluation weakens.
Compare all choices
- The number three itself.: The number remains.
- A guaranteed positive verdict on the event.: Such a verdict was not encoded.
- The speaker’s emphasis on the amount as substantial.: The numerical estimate can remain while evaluation weakens.
When an exact total is needed but only some fifty is supplied, what is responsible?
Mark the total as approximate or seek the actual count.: Do not invent missing precision.
Compare all choices
- Mark the total as approximate or seek the actual count.: Do not invent missing precision.
- Add ten to make the estimate safer.: That invents another number.
- Record exactly fifty as verified.: That misrepresents the source.
Use it in your own words
An emphatic quantity
Describe a fictional activity with a good plus a number, then make the approximate nature clear.
Reveal a possible response
Sorting the costumes took a good four hours. I didn’t time it exactly, but it was a substantial job.
- Use the marked pattern
- Avoid fake precision
Other practical activities are acceptable.
Total or subset
Contrast some fifty guests with some of the fifty guests in a coherent account.
Reveal a possible response
Some fifty guests attended the preview. In a different event with exactly fifty registered guests, some of the fifty stayed for questions.
- Keep the two reference systems distinct
- Do not silently join incompatible counts
You may instead use one exact group and explain the contrast directly.
Put it all together
A fictional charity rehearsal log says a good two hours and some forty attendees; twelve feedback forms were counted. Give a neutral report that preserves which quantities are exact.
Reveal a possible response
The rehearsal lasted roughly two hours, described as a substantial session. Approximately forty people attended. Twelve feedback forms were counted. Only the form total is exact in the supplied record.
- Preserve approximation and evaluation
- Distinguish the counted figure
- Transfer to source-based reporting
Do not invent attendance precision or a response rate.
Take it with you
Marked quantity phrases can add approximation or evaluation. A good three hours does not mean the time was enjoyable. Keep neutral quantity and speaker assessment distinct.
