   Answer

   Scientists may have found a strong new clue about dinosaur blood.

   The article focuses on a possible new clue and its limits.

   For now, the key point is that some scientists consider it their strongest evidence yet of dinosaur blood.

   3. It has already changed how museums display fossils.
   4. It proves that soft parts always last a long time.

   Answer

   It may be important, but it is not certain yet.

   The article says the finding still needs confirmation.

   They think they have found evidence; the finding is not presented as certain proof.

3. Question 3 · Single choice

   Choose one answer.

   In the sentence about a footprint, what does “its” refer to?

   Return to the passage, recording or visual
   1. The footprint

   Return to the passage, recording or visual
   1. To explain why a possible blood clue is unusual
   2. To show that bones are more valuable than eggs
   3. To identify where the scientists found the clue
   4. To prove that blood lasts longer than bone
   Check answers and explanations

   Answer

   To explain why a possible blood clue is unusual

   The comparison explains why a blood clue would be unusual.

   Blood is different because it is soft, rather than hard like bone.

5. Question 5 · Single choice

   Choose one answer.

   How is the article organized after it introduces the possible finding?

   Return to the passage, recording or visual

   2. It explains what is unknown, compares evidence types, and notes possible value.
   3. It describes a dinosaur’s life, then tells how it died.
   4. It lists research steps and gives a final scientific result.
   Check answers and explanations

   Answer

   It explains what is unknown, compares evidence types, and notes possible value.

   It gives limits, compares clues, then describes possible value.

   Bones, eggs, and footprints can each tell researchers different things about animals from the past.

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.
