How to approach this practice

Read the questions, then listen before opening the transcript. Notice names, numbers and any corrections the speaker makes.

1. Question 1 · Single choice

   Choose one answer.

   What do the Rangers take residents into?

   Return to the passage, recording or visual
   1. Municipal offices
   2. Back alleys
   3. Research laboratories
   4. Public parks
   Check answers and explanations

   Answer

   Back alleys

   The recording states that residents are taken into back alleys for direct observation.

   They take people into back alleys to illuminate the problem, turning an issue that might otherwise remain out of sight into something residents can observe directly.

2. Question 2 · Single choice

   Choose one answer.

   What happens before the initiative’s broader strategy is explained?

   Return to the passage, recording or visual
   1. Residents adopt specified sanitation practices.
   2. The source details a formal curriculum.
   3. Persistent rat survival is established.
   4. Officials announce a guaranteed outcome.
   Check answers and explanations

   Answer

   Persistent rat survival is established.

   The narration first establishes that rats continue thriving despite poison.

   No matter how much poison is put out, rats continue to thrive.

3. Question 3 · Single choice

   Choose one answer.

   Why might residents need to become part of the response?

   Return to the passage, recording or visual
   1. They possess specialized biological expertise.
   2. They live alongside the unresolved problem.
   3. They have requested stronger poisons.
   4. They manage every municipal alleyway.
   Check answers and explanations

   Answer

   They live alongside the unresolved problem.

   Their living environment continues experiencing the problem despite the existing approach.

   If the problem persists despite that approach, the people living alongside it may need to become part of the response.

4. Question 4 · Single choice

   Choose one answer.

   What does the source not specify?

   Return to the passage, recording or visual
   1. The program’s existence
   2. The residents’ involvement
   3. The precise practices expected
   4. The use of back alleys
   Check answers and explanations

   Answer

   The precise practices expected

   The recording explicitly withholds details about the particular practices residents should adopt.

   The source does not provide a detailed account of the lessons or specify which particular practices residents are expected to adopt.

5. Question 5 · Single choice

   Choose one answer.

   What immediate effect do the visits have on residents’ understanding?

   Return to the passage, recording or visual
   1. They make the issue more observable.
   2. They eliminate the rat population.
   3. They provide detailed scientific training.
   4. They guarantee behavioral compliance.
   Check answers and explanations

   Answer

   They make the issue more observable.

   The visits transform an unseen issue into one residents can directly observe.

   They take people into back alleys to illuminate the problem, turning an issue that might otherwise remain out of sight into something residents can observe directly.

6. Question 6 · Single choice

   Choose one answer.

   What does the recording say poison may represent?

   Return to the passage, recording or visual
   1. A permanent solution
   2. A symptom-oriented measure
   3. An educational encounter
   4. A resident-led experiment
   Check answers and explanations

   Answer

   A symptom-oriented measure

   Repeated poison use is characterized as treating an immediate symptom rather than wider conditions.

   The approach also draws a distinction between treating a symptom and examining the wider situation.

7. Question 7 · Single choice

   Choose one answer.

   How does the program involve residents in practice?

   Return to the passage, recording or visual
   1. Through nationwide online courses
   2. Through repeated resident visits
   3. Through compulsory neighborhood inspections
   4. Through laboratory testing of poison
   Check answers and explanations

   Answer

   Through repeated resident visits

   Its method is a series of visits that expose residents to the problem’s setting.

   In D.C., the Rat Rangers are testing that idea through education, one resident visit at a time.

8. Question 8 · Single choice

   Choose one answer.

   What does the final sentence imply about the program’s scale?

   Return to the passage, recording or visual
   1. It is being implemented incrementally.
   2. It has already become national policy.
   3. It operates without resident participation.
   4. It focuses exclusively on chemical treatment.
   Check answers and explanations

   Answer

   It is being implemented incrementally.

   The phrase suggests a gradual, resident-by-resident implementation rather than immediate mass change.

   In D.C., the Rat Rangers are testing that idea through education, one resident visit at a time.

What to review next

Listen again to difficult sections, then open the transcript to check what you heard. Repeat a useful phrase aloud and try the recording once more without the text.

A focused practice result shows how you did on these tasks. Use several activities across skills to decide what to study next; one practice score does not certify an overall CEFR level.

Before you practise: a worked example

Listen for the final information, especially when a speaker corrects or changes an earlier statement.

Example transcript: “Let’s meet at five — actually, half past five would be better.” What is the final suggested time?

The final suggested time is 5:30. Actually signals a correction; the first time is replaced by the later suggestion.

This teaching example is separate from the scored questions. After your test, compare any mistakes with the explanation and revisit the topic before trying again.
