Content note: Fictional medical drama: illness, vomiting, distress and dismissive or sexist remarks. Questions assess what the characters say, not whether a diagnosis is medically correct. Do not use the scene as health advice.

Warm-up: A website stops working just after a change. Is the change definitely the cause? What else would you need to know?

Learn the words, watch, then check your understanding. Practise the phrases and brief speaking tasks. Finish with the mastery quiz and final conversation.

Vocabulary helps you discuss the scenes; not every entry is spoken in the clips.

Speaking · 3 brief prompts

Answer aloud for 20–45 seconds. Add a reason or example. With a tutor, ask one follow-up question.

  1. How does the time pressure affect the conversation?
    One possible answer

    It makes delaying a decision seem consequential, even though the cause is uncertain.

  2. What is the difference between considering a risk and proving it exists?
    One possible answer

    Considering it may justify checking further; proving it requires supporting evidence.

  3. Rephrase an overconfident claim about a broken website.
    One possible answer

    Instead of “The update caused it”, say “The timing suggests a connection, but we should test it”.

When a test changes the explanation

House makes an announcement to the passengers and then revises the explanation of the apparent wider outbreak.

First watch: What does the announcement reveal, and what remains unexplained?

Open the original source to watch.

Watch and check · 6 questions

All six questions refer to this clip. Choose one answer per question.

Interpret the scene1. What is House doing when he names an additional symptom in the announcement?

Listen for the evidence2. Which new symptom does he introduce for that test?

Answer key and explanations

  2. C. A tremor in the left hand. Correct. The exact symptom matters because it is deliberately suggested.
  3. C. They begin showing or reporting the suggested symptom. Correct. Their response becomes part of his reasoning.
  4. A. Meningitis. Correct. House explicitly says the left-hand tremor is not a symptom of meningitis and explains that he planted the idea.
  5. A. The effect of suggestion and shared anxiety. Correct. This is the character’s explanation of the wider response.
  6. B. A complimentary bar service. Correct. He announces a complimentary bar service as part of his attempt to calm the passengers.

Useful phrases

Original language for practice, not programme quotations.

That fits some of the evidence, but it does not explain everything.
Acknowledge partial support without overstating it.

We should revise the explanation, not ignore the new result.
Respond constructively to disconfirming information.

Speaking · 3 brief prompts

Answer aloud for 20–45 seconds. Add a reason or example. With a tutor, ask one follow-up question.

  1. Why is it important that the original case remains unresolved?
    One possible answer

    One explanation can account for part of a situation without accounting for the whole.

  2. Can the way a question is asked influence an answer?
    One possible answer

    Yes. A leading description can prompt people to notice or report a particular detail.

  3. Explain a changed view without sounding defensive.
    One possible answer

    I initially thought the update was responsible, but the new test suggests we should check the connection instead.

Put it together

Final speaking · 12 minutes

A small organisation’s booking page has stopped loading for some users. Compare explanations, request evidence and revise your account when a new clue arrives. This is a non-medical investigation.

Role A

You coordinate bookings. The problem was first reported after a text update, so you suspect the update. You know two affected users work in the same building.

Role B

You support the website. You know the page opens on your phone. Halfway through the conversation, reveal that both affected users can open it after changing to another network.

Practise

  1. State a working hypothesis and at least one alternative.
  2. Choose a useful comparison rather than defending the first explanation.
  3. Introduce the new clue and revise the account.
  4. Summarise what is supported, what remains unresolved and the next check; retry after feedback.

On your own: Speak both roles aloud, then improve your closing response.

Success criteria

  • Use calibrated certainty rather than unsupported claims.
  • Respond explicitly to the new clue.
  • Separate a partial explanation from a completed investigation.
One possible conversation

Coordinator: The reports began after the update, so that is my working hypothesis.

Support: It is possible, but the page opens on my phone. Could their connection be a confounding factor?

Coordinator: What evidence would distinguish the two explanations?

Support: They have now tried a different network, and it opens there.

Coordinator: Then we should revise the explanation. The update may not be the cause.

Support: Agreed. We should check the shared network, although the exact fault remains unresolved.

Try it again

A third user reports the problem from another location. Reopen the investigation without claiming the earlier clue was useless.

Finish by choosing two useful expressions and saying how you could use them.
