The Cost of Silence

Explain a cause-and-effect relationship, distinguish evidence from reassurance and communicate an unwelcome concern clearly.

Created by , British English teacher.

Content note: Adults: a historical disaster, possible strong language and serious harm discussed in dialogue. Use dialogue-only extracts without graphic injuries. This is historical drama, not a documentary or a safety manual.

Warm-up: A project report says that everything is on schedule, but one important test has not been completed. What would you ask before accepting the reassurance?

Learn the words, watch, then answer the quiz. Practise the phrases and speaking prompts. On your own, replay only what you need; with a tutor, develop each response together.

Vocabulary helps you discuss the scene; not every entry is spoken in the clip.

Answer key and explanations
  1. C. The situation is presented as less dangerous than Legasov fears. The reassuring account is what he challenges.
  2. A. Details in the report that do not fit the reassuring explanation. He points to evidence and inconsistencies rather than relying only on confidence.
  3. B. That the reactor core may be exposed and the danger greater than reported. This is the serious alternative that needs investigation.
  4. C. He asks whether Legasov’s concern rests on the description of a rock. Gorbachev questions the basis of Legasov’s concern before the clip ends.
  5. A. The test is incomplete, so the deadline may be less secure than the report suggests. The speaker states what is known and qualifies the implication.
  6. B. What evidence has been checked, and what remains unverified? This asks for the basis and limits of the claim.

Develop your answer with a reason or example. On your own, answer aloud before opening a model.

  1. What makes Legasov’s intervention more than an expression of anxiety?
    One possible answer

    He identifies information that does not fit the reassuring conclusion. His concern can therefore be investigated rather than accepted or dismissed simply as a feeling.

  2. Why might a team prefer a reassuring summary even when it is incomplete? Give two possible explanations without assuming bad intentions.
    One possible answer

    A team may be under time pressure or may trust the person who prepared it. They may also lack the expertise to recognise a gap. Those possibilities make a clear verification process important.

  3. Role-play a project meeting: a launch is marked ready, but a required compatibility test is unfinished. State the fact, explain a possible consequence and request one practical next step.
    One possible answer

    Analyst: The report says ready, but the compatibility test is incomplete. Manager: Is that enough to delay the launch? Analyst: I cannot predict the result. Before we proceed, could we finish that test and review the decision tomorrow?

Explaining the chain of events

In the dramatised hearing, Legasov uses a visual explanation to connect decisions with the accident.

First watch: How does a hidden problem change the meaning of a safety measure?

About the clip: picture and dialogue1. What does the scene show while Legasov explains the shutdown and its consequences?

About the clip: listening2. What was the shutdown action supposed to do?

About the clip: listening3. What problem does Legasov describe in the dramatised explanation?

About the clip: listening4. According to the scene, what limited the operators’ understanding of that danger?

Original language practice (not a quote)5. Which explanation makes a causal link rather than merely a sequence?

Original language practice (not a quote)6. Which question explores accountability without assuming a motive?

Interactive scoring needs JavaScript. Use the answer key to check your choices.

Answer key and explanations
  1. A. The control room and reactor as the events unfold. The scene cuts between Legasov’s testimony and images of the plant and its operators.
  2. B. Stop the reactor’s reaction safely. Its intended purpose was to reduce and stop the reaction.
  3. C. A design flaw could initially increase the reaction during shutdown. The explanation contrasts the intended effect with the dangerous initial effect under those conditions.
  4. A. Important information about the flaw had been withheld. The scene links incomplete knowledge with concealed information.
  5. B. Because the file was incomplete, the reviewer could not check the missing figures. Because explains how one condition affected another.
  6. C. Who knew about the limitation, and how was that information communicated? It asks for relevant facts before judging why people acted as they did.

Useful phrases

Original phrases to practise, not programme quotations.

The problem was not only the decision, but the information available when it was made.
Connect a decision with its information context.

Let me explain the chain of events one step at a time.
Organise a cause-and-effect explanation.

Speaking · 3 prompts

Develop your answer with a reason or example. On your own, answer aloud before opening a model.

  1. How do the switches between the hearing and events at the plant help explain a complicated process? What might the audience still need to know?
    One possible answer

    The cutaways let us connect Legasov’s explanation with the people and machinery involved. We still need to ask which parts are a dramatisation and which details are established by evidence.

  2. What is the difference between identifying a mistake and explaining how an organisation allowed it to happen?
    One possible answer

    Identifying a mistake names an action. Explaining the wider process asks about information, checks, incentives and responsibility. A useful review can examine both without assuming that one person explains everything.

  3. Explain a harmless chain of errors: an old timetable is sent, a room booking changes, and a team misses a meeting. Your partner asks where verification or clearer ownership could have interrupted the chain.
    One possible answer

    First, an outdated timetable was circulated. Because no one checked the revision date, the team relied on it. The room change was then sent to only one person. A single current timetable and a named contact could have interrupted the sequence.
