Your goal

Integrate findings from sources with different purposes and samples, distinguish evidence from interpretation, and communicate a proportionate recommendation to a non-specialist audience.

Before you start

You should be able to sustain a reasoned comparison and qualify a claim, as in B2 Unit 1. Here, the challenge is not simply to list what each source says: you must explain how the sources relate and what remains uncertain.

1. Pre-check: write a briefing before seeing a model

A community panel must decide whether to expand a learning-evenings pilot or continue it at its present size. Read Documents A–C, then draft a 180–240-word briefing. Integrate at least two sources, explain an important limitation and recommend a next step. Distinguish the existing findings from any measures you propose. Keep your draft as “Before”. The word range is a guide.

Document A — organizer’s six-week report

Forty people registered for the learning evenings. Twenty-eight attended at least one session. At the final session, 20 participants completed an optional questionnaire; 16 described the activities as helpful. The report concludes that the pilot shows promise and recommends doubling the number of groups.

The report provides no entry assessment or comparison group and does not say whether the questionnaire respondents attended more regularly than other participants. It records participation and perceived usefulness, not measured language improvement.

Document B — volunteer interviews

A volunteer interviewed 12 people who had registered. Five mentioned transport difficulties and four said the activity pace was sometimes too fast. These categories may overlap. The notes do not explain how interviewees were selected or whether they also answered the questionnaire.

Several interviewees valued the supportive atmosphere, but the notes do not give a count for that view. The volunteer recommends improving access and pacing before expansion. The interviews identify concerns worth investigating; they do not show how common those concerns are among all registrants.

Document C — coordinator’s capacity note

The current pilot uses eight volunteer preparation hours per week. The same volunteer time is available for another six weeks. The coordinator has not estimated the hours needed for twice as many groups. She can keep a consistent attendance record and add a short, common language task at the start and end of the next cycle, provided these checks fit within the existing preparation time.

The panel must choose a next step under uncertainty. It is not required to declare the pilot a success or a failure.

2. Presentation: compare your briefing with a model

“The evidence supports continuing the pilot at its present size while addressing access and pacing, rather than immediately doubling the groups. The organizer’s report offers an encouraging signal: 16 of 20 questionnaire respondents found the activities helpful. However, that figure represents respondents, not all 40 registrants, and it measures perceived usefulness rather than language gains (Document A).

The interviews add a different perspective. Transport and pacing concerns suggest practical changes to investigate, although the unknown selection process and possible overlap with questionnaire respondents prevent us from treating the two sources as independent confirmation of a general pattern (Document B). Positive comments and concerns can coexist.

Capacity also remains unresolved. Eight preparation hours are available each week, but no estimate has been made for an expanded service (Document C). I recommend a further six-week cycle at the current scale, with clearer attendance records and a manageable common task before and after participation. Staff should also record which access or pacing adjustments they try. These are proposed checks, not findings already established. The panel could then review participation, task performance and volunteer workload together. Even improved task results would require cautious interpretation without a comparison group.”

Notice the synthesis

A shared theme is developed across sources instead of presenting three unrelated summaries.
The denominator stays visible: 16 of 20 respondents is not 16 of all participants or proof about all registrants.
Evidence about satisfaction, access and capacity answers different questions.
The recommendation is proportionate to the information available; it does not turn uncertainty into either certainty or paralysis.

3. Practice: inspect the reasoning

1. Is “80% of registrants found the pilot helpful” accurate?

No. Sixteen of 20 questionnaire respondents is 80% of respondents. There were 40 registrants, and the views of the non-respondents are not reported.

2. Can we add five transport concerns and four pacing concerns to claim nine dissatisfied people?

No. The categories may overlap, and reporting a concern does not necessarily mean overall dissatisfaction. The sources do not provide that conclusion.

3. Does Document B disprove Document A?

No. Helpful activities can still be difficult to reach or too fast for some people. The sources have different purposes and unknown sample relationships.

4. Would a before-and-after task prove that the program caused an improvement?

Not by itself. It could provide evidence of change in performance on the selected tasks, but without a comparison group other explanations remain possible.

Revise the claim

Rewrite: “The pilot improved language skills for most learners.”
Rewrite: “The interviews confirm the survey.”
Explain the difference between “we observed” and “we propose to check”.
Write one sentence that connects an encouraging signal with a practical uncertainty.

Possible revisions

“Most questionnaire respondents described the activities as helpful; language improvement was not measured.” “The interviews add concerns about access and pacing, but their relationship to the survey sample is unknown.” “The survey suggests perceived value, while the capacity note leaves the feasibility of expansion unresolved.”

4. Production: brief a mixed audience

Revise your original briefing for a panel that includes learners, volunteers and a funder. Attribute evidence to Documents A–C. Include an encouraging finding, a limitation, a practical recommendation and a review condition. You may recommend a different next step if you explain its risks and resource assumptions.

Then give a two-minute spoken briefing in plain English. Explain one technical limitation without hiding behind specialist vocabulary. If a partner is available, ask them to challenge your strongest claim. Respond by clarifying or revising it rather than defending it automatically.

If studying alone, record a likely challenge and your response. Note one place where you made the information easier to understand without changing its meaning.

Review with four checks

Score each area 0–3 using evidence from your response. If you have not attempted the task, write “Not tried yet”. These scores describe this task; they do not award a CEFR level or predict an exam score.

Task completion

0 — The briefing does not communicate a defensible interpretation or next step.
1 — Sources are mainly listed or important findings are misrepresented; the recommendation is weakly connected to the evidence.
2 — Relevant sources are integrated accurately, limitations are explained and the recommendation is proportionate.
3 — The briefing also handles tensions and uncertainty insightfully, distinguishing existing evidence, assumptions and proposed checks.

Clear meaning and organization

0 — The argument cannot yet be followed.
1 — Source summaries and conclusions are linked loosely or leave important reasoning implicit.
2 — The reader can follow a coherent synthesis from findings through limitations to recommendation.
3 — A controlled structure and selective emphasis make a complex relationship accessible without oversimplification.

Fit for the situation and interaction

0 — The response disregards the audience or seriously misrepresents a source or opposing view.
1 — Some adaptation is evident, but technical wording, attribution or overconfidence obstructs understanding.
2 — Register and explanation suit a mixed audience; attribution is clear and challenges are handled fairly.
3 — The response mediates competing perspectives sensitively and makes precise qualifications accessible to non-specialists.

Language range and control

0 — There is not enough language control to convey the analysis reliably.
1 — Imprecision or errors blur source relationships, qualifications or the writer’s stance.
2 — Flexible, appropriate language conveys synthesis and qualification accurately, with occasional minor weaknesses.
3 — Precise wording, varied structures and well-controlled cohesion express subtle distinctions efficiently.

5. Post-check: work with fresh sources

A panel is now reviewing a separate four-session digital-reading workshop. Use these new documents. Do not import any facts from the first pilot.

Document D — workshop summary

Sixty people registered and 36 attended at least once. Eighteen attendees completed an optional feedback form; 12 rated the workshop useful. There was no baseline task or comparison group. The organizer recommends running more workshops.

Document E — follow-up notes

A facilitator spoke with ten registrants who were available for follow-up. Six wanted slower demonstrations. Selection was not random, and overlap with feedback respondents is unknown. The notes do not show how many of the ten attended each session.

Document F — delivery note

The current volunteers can deliver one further cycle at the same scale. Extra workshops would require additional volunteers, who have not yet been recruited. A short demonstration-and-response task could be trialled in the next cycle, but no results from such a task exist yet.

Write a fresh 180–240-word briefing for the panel. Integrate the evidence, explain a sample or measurement limitation, recommend a practical next step and state what further information would inform a later decision. Review it with the same rubric.

Check the boundaries of the evidence

Twelve of 18 respondents rated the workshop useful; that is not a finding about all 60 registrants. Six interviewees wanted slower demonstrations, but the selection and sample overlap are unclear. No language or digital-reading improvement has been measured. Another cycle at the same scale is currently supported by capacity; expansion depends on additional volunteers.

One possible response — read after your own attempt

“I recommend one further cycle at the present scale, with slower demonstrations and a clearer review process, before scheduling additional workshops. The feedback offers a positive signal: 12 of 18 respondents rated the workshop useful. However, the optional form does not establish the views of all 60 registrants, and no baseline or comparison data show an improvement in performance (Document D). Six of ten people reached for follow-up wanted a slower pace, which provides a reason to test a pacing adjustment. Their availability-based selection and unknown overlap with feedback respondents limit any estimate of how widespread that need is (Document E). Capacity also favors a limited continuation: existing volunteers can support another cycle, whereas expansion would require people who have not been recruited (Document F). I would record attendance consistently and trial the proposed demonstration-and-response task, while checking that this review work remains manageable. The panel should then consider participation, responses to the revised pace, task performance and confirmed volunteer capacity together. These checks may strengthen a later decision; they should not be presented as results already obtained or, by themselves, proof of program impact.”

Listening practice for this unit

Listen for meaning

Listen before opening the transcript. For practice, listen once for the main point and again for details. Record replays or slower playback with your result.

Listen in American English

Audio uses an American English voice available on your device. Pause and Stop appear when a session starts.

What distinction matters?
Why is independent confirmation uncertain?

Transcript — open after listening

Positive ratings show perceived value among respondents, not measured language gains. The interview sample may overlap with the survey and was selected differently. These sources can inform a cautious continuation without independently confirming a general impact claim.

Listening answers and reasons

Perceived value versus measured gains. Selection and overlap are unclear.

If you read the transcript before answering, record that as supported practice rather than an independent listening check.
