Choose a short recording.

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.

Only the blonde woman considers a booking-limit change shown by a moved capacity slider on a booking sheet with indistinct unnumbered markers and a calendar. The scene does not identify who changed it or imply absence of a cause.
The booking limit changed on Monday.This does not prove that no person or cause was involved.

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

the price rosethe organiser raised the pricethe price was raised by the organiser
Rise is intransitive here. Raise takes an object, and its passive can retain the supported agent in a by-phrase. Do not force every change verb into one pattern.
All three supplied adults act as a committee, deliberately changing the same booking-limit slider together, with a meeting folder and calendar. Their agency is now explicit, with no unrelated bookings or invented numeric limit.
The committee changed the booking limit on Monday.The related passive can retain this agent: the limit was changed by the committee.

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.

Listening checks

Listen to each extract, then choose the best answer. These three questions have their own score.

1. What does the note establish?
Read the listening transcript

The opening time changed yesterday. This short note doesn’t say who made the change or why.

2. Who is identified as causing the increase?
Read the listening transcript

The organiser raised the entry price. As a result, the price rose from five to six units. This is a fictional event description.

3. What remains unspecified?
Read the listening transcript

The file was changed by Rae. We know the actor, but the source does not explain Rae’s reason.

Answer key with explanations
  1. What does the note establish?

    A change in opening time.: The event is stated; actor and reason are not.

    Compare all choices
    • That the writer is deliberately concealing the actor.: No motive is supplied.
    • A change in opening time.: The event is stated; actor and reason are not.
    • That no person caused the change.: Lack of a named actor does not establish that.
  2. Who is identified as causing the increase?

    The organiser.: Raised takes the price as object and names its causer.

    Compare all choices
    • The price itself as a deliberate actor.: The price is the affected item, not a deliberate actor.
    • An unnamed visitor.: No visitor is identified.
    • The organiser.: Raised takes the price as object and names its causer.
  3. What remains unspecified?

    The reason for the change.: The actor is named, but the motive is not.

    Compare all choices
    • The reason for the change.: The actor is named, but the motive is not.
    • Whether a change is reported.: The change is stated.
    • The identity of the actor.: Rae is explicitly named.

Mastery quiz

Choose the best answer for each situation. The score is out of eight.

1. What does The limit changed alone not establish?
2. Which version names an actor supported by Note B?
3. Which passive version retains the source-supported actor?
4. Which statement about an omitted agent is justified?
5. Choose the standard pair for an increase in price and its human cause.
6. Which sentence describes a general property rather than one specific event?
7. You have Note A but not Note B. Which report stays within the evidence?
8. Which editing principle is strongest?
Answer key with explanations
  1. What does The limit changed alone not establish?

    That no person caused the change.: An unexpressed actor is not a nonexistent actor.

    Compare all choices
    • That no person caused the change.: An unexpressed actor is not a nonexistent actor.
    • That the limit is the thing affected.: The limit is the changing entity.
    • That a change is being reported.: The verb reports a change.
  2. Which version names an actor supported by Note B?

    The committee changed the limit from two hours to three.: Both actor and values come from Note B.

    Compare all choices
    • A visitor secretly changed the limit.: Neither visitor nor secrecy is supplied.
    • The committee changed the limit from two hours to three.: Both actor and values come from Note B.
    • The limit deliberately changed itself.: This invents deliberate agency for the limit.
  3. Which passive version retains the source-supported actor?

    The limit was changed by the committee.: The by-phrase names the agent.

    Compare all choices
    • The limit changed the committee.: This also changes the affected entity and actor.
    • The committee was changed by the limit.: This reverses the roles.
    • The limit was changed by the committee.: The by-phrase names the agent.
  4. Which statement about an omitted agent is justified?

    Its omission alone does not reveal the writer’s motive.: Omission is not sufficient evidence of concealment or ignorance.

    Compare all choices
    • Its omission alone does not reveal the writer’s motive.: Omission is not sufficient evidence of concealment or ignorance.
    • It always proves concealment.: That invents a motive from grammar alone.
    • It always proves the actor is unknown to everyone.: A known actor can be omitted for other reasons.
  5. Choose the standard pair for an increase in price and its human cause.

    The price rose; the organiser raised it.: Rise and raise have different object patterns here.

    Compare all choices
    • The organiser raised; the price rose the organiser.: The stated roles and complements do not fit the intended event.
    • The price rose; the organiser raised it.: Rise and raise have different object patterns here.
    • The price raised; the organiser rose it.: These forms reverse the required patterns.
  6. Which sentence describes a general property rather than one specific event?

    This material bends easily.: Present simple here describes a tendency.

    Compare all choices
    • The material bent during the test yesterday.: This reports a particular event.
    • Jo bent the material at noon.: This identifies a particular caused event.
    • This material bends easily.: Present simple here describes a tendency.
  7. You have Note A but not Note B. Which report stays within the evidence?

    The limit changed on Monday; the note names no agent.: It states the event and the source limit.

    Compare all choices
    • The limit changed on Monday; the note names no agent.: It states the event and the source limit.
    • No one made the change.: That is not established either.
    • The committee definitely made the change.: Note A alone does not supply that actor.
  8. 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.
