Before you start
Report a change without naming its cause.
See one possible response
The booking limit changed.
A fictional photography club changes its equipment-booking policy. Note A says only that the booking limit changed on Monday. Note B separately confirms that the committee changed the limit from two hours to three. These are fictional internal arrangements, not public policy or legal guidance.
What you will practise
- Separate a reported change from an explanation of its cause.
- Compare active, passive and intransitive descriptions without inventing motives.
- Reformulate a change report while preserving supported agency and lexical patterns.
Respond before revealing. Preserve scope, attribution and evidence limits. A defensible alternative or genuine ambiguity must not be marked wrong merely for differing from the model.
A change is not a cause explanation
The policy changed reports a change without grammatically naming a changer. It does not prove that the change had no cause or that no person was involved. Some verbs allow a related transitive form: the committee changed the policy. Others require a different verb or structure.
The booking limit changed on Monday.
The committee changed the booking limit on Monday.

Passive voice leaves the agent unexpressed
The limit was changed presents it as affected by a changing event while leaving the agent unexpressed. An optional by-phrase can identify that agent when known. Omitting the agent does not itself prove ignorance, concealment or lack of responsibility.
The booking limit was changed from two hours to three.
The booking limit was changed by the committee.
Match the report to the evidence
Use Note A for a source-limited change report; use Note B when naming the committee. Do not apply one alternation to every verb: the price rose, but the organiser raised the price. Choose a natural structure and retain the distinction between known event, known actor and inferred cause.
Note A records a change but does not identify who made it.
Note B identifies the committee as the agent of the change.
Related meanings can require different verbs

Guided practice
Say or write your answer first. Then compare the meaning and grammar with the model.
1. Compare The door opened with Jo opened the door.
Compare a model and explanation
The first reports opening without naming a causer; the second identifies Jo as causing it.
The intransitive version does not rule out a person opening it.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
2. Use Note B to put the booking limit first and retain the committee.
Compare a model and explanation
The booking limit was changed by the committee from two hours to three.
Other natural placements of the by-phrase are acceptable.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
3. Does Note A alone establish that the committee made the change?
Compare a model and explanation
No. It reports the change but does not name its agent.
Note B is the separate evidence for the committee.
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 report omits the agent. Does that prove deliberate concealment?
Compare a model and explanation
No. Motive cannot be inferred from omission alone.
Context could explain the omission in several ways.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
5. Correct The organiser rose the price.
Compare a model and explanation
The organiser raised the price.
Raise takes the affected price as object; rose is the past of intransitive rise.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
6. Compare The glass broke with This glass breaks easily.
Compare a model and explanation
The first reports a particular event; the second describes a general tendency or property.
Do not confuse a specific change report with a middle-style property description.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
7. First use Note A, then update the report after reading Note B.
Compare a model and explanation
Initially, we knew only that the limit changed. Note B identifies the committee and says it changed the limit from two hours to three.
The stronger attribution is licensed by new evidence.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
8. An unsupported draft says The limit changed itself because the committee was hiding something. Replace it using Note A only.
Compare a model and explanation
The booking limit changed on Monday; Note A gives no actor or motive.
The repair removes an invented self-cause and an invented motive.
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
Club member: The booking limit changed on Monday. Do we know who changed it?
Secretary: Note A doesn’t say, but Note B names the committee.
Club member: Then we can write that the committee changed it from two hours to three.
Secretary: Yes. We shouldn’t infer a motive that neither note gives.

- An unnamed visitor.: No visitor is identified.
- The organiser.: Raised takes the price as object and names its causer.

Which editing principle is strongest?
Match agency and causation to the evidence and the verb’s actual pattern.: Both source fidelity and lexical grammar matter.
Compare all choices
- Add a likely actor whenever a sentence seems vague.: Likelihood is not source support.
- Match agency and causation to the evidence and the verb’s actual pattern.: Both source fidelity and lexical grammar matter.
- Convert every transitive verb into the same intransitive pattern.: Not all verbs allow the alternation.
Use it in your own words
One event, three views
Invent a low-stakes event with a known actor and a verb that allows change alternation. Give intransitive, active and passive versions.
Reveal a possible response
The display changed. The technician changed the display. The display was changed by the technician. In the first sentence, the actor isn’t expressed; that doesn’t mean there was no actor.
- Keep one event and its roles
- Use natural patterns
- Explain the difference in agent visibility
Different verbs are welcome when their patterns are natural.
Source-limited reporting
Report a change from a source that gives no cause or agent. Explain what you refuse to infer.
Reveal a possible response
The timetable changed yesterday. The note doesn’t identify a changer or a reason, so I won’t attribute it to a particular person or claim the omission is deliberate concealment.
- State the event
- Identify source limits
- Avoid invented motives
Use a fictional everyday arrangement.
Put it all together
A fictional game club first learns that a score limit changed. A later message names the organiser and states the old and new limits but no motive. Give the initial report and a justified update.
Reveal a possible response
Initially, we knew only that the limit had changed. The later message says the organiser raised it from ten to twelve. We can now name the actor and the amount of change, but we still shouldn’t invent a reason.
- Separate evidence stages
- Use rise
- raise or another valid pattern
- Strengthen only supported details
This is a fictional grammatical case, not an evaluation of a real organisation.
Take it with you
An intransitive change report does not prove there was no cause. Passive voice can leave an agent unexpressed. Name an actor only when evidence supports it, using the verb’s natural pattern.
