How to approach this practice

Read the passage for its main idea, then return to the relevant sentence or paragraph for each question. Base answers on the passage.

1. Question 1 · Single choice

   Choose one answer.

   What is the article’s central purpose?

   Return to the passage, recording or visual
   1. To document a rescue operation during a tropical storm
   2. To explain the arch’s disappearance and its geological significance
   3. To compare Hawaii’s arches with museum collections
   4. To argue that coastal erosion is entirely predictable
   Check answers and explanations

   Answer

   To explain the arch’s disappearance and its geological significance

   It explains the arch’s loss while placing it within broader coastal processes.

   The event is also a reminder that natural attractions are not preserved in the same way as buildings or museum objects.

2. Question 2 · Single choice

   Choose one answer.

   Why does the article describe familiar landmarks as seemingly permanent?

   Return to the passage, recording or visual
   1. Their apparent permanence reflects familiarity rather than invulnerability
   2. Their geological origins are usually unknown to visitors
   3. Their surfaces are protected from weathering by public attention
   4. Their locations make them less exposed than ordinary coastlines
   Check answers and explanations

   Answer

   Their apparent permanence reflects familiarity rather than invulnerability

   Familiarity can obscure the ongoing physical conditions supporting a formation.

   Natural landmarks can seem permanent because they remain familiar across many years, yet their survival depends on the continuing strength of the rock from which they are formed.

3. Question 3 · Single choice

   Choose one answer.

   In the fourth paragraph, what does “Its shape” refer to?

   Return to the passage, recording or visual
   1. The surrounding coast
   2. The opening created by erosion
   3. A sea arch
   4. The water beneath the formation
   Check answers and explanations

   Answer

   A sea arch

   The pronoun refers directly to the sea arch introduced in the preceding sentence.

   Its shape may look solid and balanced, but it is the result of a long process rather than a fixed structure.

4. Question 4 · Single choice

   Choose one answer.

   What relationship does the article establish between erosion and collapse?

   Return to the passage, recording or visual
   1. Erosion strengthens arches before storms remove them
   2. Erosion gradually alters arches and may ultimately destabilize them
   3. Erosion occurs only after an arch has already collapsed
   4. Erosion prevents coastal formations from changing shape
   Check answers and explanations

   Answer

   Erosion gradually alters arches and may ultimately destabilize them

   Erosion progressively weakens an arch until its stability is lost.

   As the surrounding coast continues to change, an arch can become narrower or less stable until it eventually collapses.

5. Question 5 · Single choice

   Choose one answer.

   Why does the article qualify the storm’s explanatory role?

   Return to the passage, recording or visual
   1. To deny that weather affects geological formations
   2. To distinguish contextual explanation from precise prediction
   3. To show that storms affect only artificial structures
   4. To suggest the arch collapsed before the storm arrived
   Check answers and explanations

   Answer

   To distinguish contextual explanation from precise prediction

   The storm provides context without making the exact collapse mechanically predictable.

   That does not make every coastal change predictable, but it helps explain why exposed rock formations are vulnerable during severe weather.

6. Question 6 · Single choice

   Choose one answer.

   How is the final paragraph organized?

   Return to the passage, recording or visual
   1. By presenting a chronology of Hawaii’s volcanic eruptions
   2. By comparing preservation of nature with preservation of manufactured objects
   3. By listing competing explanations for the arch’s collapse
   4. By shifting from geology to emergency management procedures
   Check answers and explanations

   Answer

   By comparing preservation of nature with preservation of manufactured objects

   It contrasts natural attractions with human-made objects before describing landscape transformation.

   Their value often lies in their unaltered form and in the processes that created them.

7. Question 7 · Single choice

   Choose one answer.

   What broader conclusion does the article invite about natural attractions?

   Return to the passage, recording or visual
   1. Their value depends exclusively on maintaining familiar shapes
   2. Their disappearance can reveal the continuing forces that created them
   3. Their preservation is generally more reliable than architectural preservation
   4. Their geological importance ends once visitors can no longer see them
   Check answers and explanations

   Answer

   Their disappearance can reveal the continuing forces that created them

   Their significance includes ongoing processes, not merely their visible appearance.

   When such a formation disappears, the landscape does not simply return to an earlier state; it takes on a new form, shaped by the same volcanic and coastal forces that made the arch possible.

What to review next

Find the words that support each answer. For a mistake, compare the question with the evidence and identify the detail or inference you missed.

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

Look for evidence in the text. Separate what the writer says from what you already know about the topic.

The library normally closes at six, but on Fridays it stays open until eight. When does it close on Friday?

The answer is eight. But introduces an exception to the normal closing time, so the first time mentioned is not the answer.

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.
