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 happened when Consoli lifted one of the bags?

   Return to the passage, recording or visual
   1. He found it empty and damaged.
   2. He found it densely filled with oysters.
   3. He discovered that it contained a seahorse.
   4. He measured exactly fifty gallons of water.
   Check answers and explanations

   Answer

   He found it densely filled with oysters.

   The observation revealed a striking change in the oysters’ mass over three months.

   When he lifts one bag from the water, it is densely filled with oysters that, he says, had been nearly weightless when he received them three months earlier.

2. Question 2 · Single choice

   Choose one answer.

   What can an adult oyster filter in one day?

   Return to the passage, recording or visual
   1. Five gallons
   2. Fifteen gallons
   3. Fifty gallons
   4. Five hundred gallons
   Check answers and explanations

   Answer

   Fifty gallons

   The recording gives a specific daily filtration estimate to illustrate oysters’ ecological value.

   An adult oyster can filter as much as 50 gallons of water a day, a process that can improve water clarity and support the growth of sea grass.

3. Question 3 · Single choice

   Choose one answer.

   What did Consoli find among the oyster-created habitat?

   Return to the passage, recording or visual
   1. A seahorse
   2. A juvenile seal
   3. A freshwater turtle
   4. A colony of mussels
   Check answers and explanations

   Answer

   A seahorse

   This concrete discovery demonstrates that the artificial habitat supports varied marine life.

   Consoli says he even discovered a seahorse among the habitat formed by the oysters.

4. Question 4 · Single choice

   Choose one answer.

   By what year had overharvesting reduced oyster numbers by more than 99 percent?

   Return to the passage, recording or visual
   1. 1999
   2. 2001
   3. 2011
   4. 2021
   Check answers and explanations

   Answer

   2011

   The date identifies the historical point associated with the most dramatic documented decline.

   Oyster reefs once covered much of the Chesapeake, but overharvesting reduced their numbers by more than 99 percent by 2011, according to one estimate.

5. Question 5 · Single choice

   Choose one answer.

   What difficulties accompany the recent expansion of oyster farming?

   Return to the passage, recording or visual
   1. Tourism and shipping conflicts
   2. Environmental and disease-related difficulties
   3. Lack of suitable shell material
   4. Insufficient demand for oysters
   Check answers and explanations

   Answer

   Environmental and disease-related difficulties

   The speaker explicitly identifies environmental and disease-related obstacles.

   Oyster farming in the Chesapeake has expanded in recent years despite environmental and disease-related difficulties, according to Ryan Carnegie, a biologist at the Virginia Institute of Marine Science.

6. Question 6 · Single choice

   Choose one answer.

   Which two factors aided the partial comeback of wild oysters?

   Return to the passage, recording or visual
   1. Warmer winters and reduced salinity
   2. Improved management and restoration investment
   3. Private ownership and expanded tourism
   4. Disease resistance and deeper channels
   Check answers and explanations

   Answer

   Improved management and restoration investment

   The recording attributes limited recovery to management improvements and restoration investment.

   Wild oysters have also made a partial comeback, aided by improved management and investment in restoration.

7. Question 7 · Single choice

   Choose one answer.

   What does North say about present oyster populations?

   Return to the passage, recording or visual
   1. They exceed historic levels.
   2. They have returned to historic levels.
   3. They are probably only a fraction of historic levels.
   4. They cannot be estimated scientifically.
   Check answers and explanations

   Answer

   They are probably only a fraction of historic levels.

   Her statement supplies the recording’s clearest qualification concerning the extent of recovery.

   Still, Elizabeth North, a fisheries oceanographer at the University of Maryland Center for Environmental Science, says current oyster populations are probably only a fraction of their historic levels.

8. Question 8 · Single choice

   Choose one answer.

   What does Consoli do while adding oysters to the bay?

   Return to the passage, recording or visual
   1. He sells them to commercial harvesters.
   2. He monitors their condition.
   3. He relocates them to freshwater ponds.
   4. He removes their shells for construction.
   Check answers and explanations

   Answer

   He monitors their condition.

   His simultaneous monitoring indicates that restoration involves active stewardship and observation.

   He wants to act as a caretaker, adding more oysters to the bay while monitoring their condition.

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.
