What this part tests

Task 6 tests whether you can describe a graphic and, beyond that, form hypotheses about causes or backgrounds – a more demanding speech act.

You first give the most important data of the graphic and then form justified conjectures about why the development happens.

What matters is a clear graphic description and plausible, linguistically marked hypotheses (“könnte daran liegen, dass …”, “ein möglicher Grund ist …”).

How to approach it

  1. 1

    Introduce the graphic and describe the most important development.

  2. 2

    Mark the transition to your conjectures.

  3. 3

    Form one or two hypotheses about the causes.

  4. 4

    Justify your hypotheses plausibly.

  5. 5

    Sum up briefly at the end.

Example task with answer

A short example in the same format: the situation and a model answer.

Aufgabe

Eine Grafik zeigt: Die Zahl der Menschen, die online einkaufen, ist stark gestiegen. Beschreiben Sie die Grafik und stellen Sie Vermutungen über die Gründe an.

Model answer:

Answer: Die Grafik zeigt, dass die Zahl der Menschen, die online einkaufen, in den letzten Jahren stark gestiegen ist. Besonders auffällig ist der Anstieg seit 2020. Dieser Anstieg könnte mehrere Gründe haben. Ein möglicher Grund ist, dass während der Pandemie viele Geschäfte geschlossen waren und die Menschen auf Onlineshops ausweichen mussten. Außerdem könnte es daran liegen, dass das Bezahlen im Internet immer einfacher und sicherer geworden ist. Insgesamt vermute ich, dass sich diese Gewohnheit auch in Zukunft fortsetzen wird.

Why? The answer first describes the graphic’s development and then forms justified hypotheses about the causes, clearly marked as conjectures – exactly what Task 6 expects.

Practice: test yourself

Common mistakes

1
Only describing

Task 6 also requires hypotheses. Don’t stop at the description.

2
Not marking hypotheses

Use phrases like “könnte daran liegen, dass …” to mark conjectures clearly.

3
Implausible conjectures

Your hypotheses should fit the topic and be justified.

4
No justification

Justify why you suspect a particular cause.

Tips

  • Separate clearly: first describe, then hypotheses.
  • Use hypothesis phrases (“ein möglicher Grund könnte sein, dass …”).
  • Justify each conjecture briefly.

Frequently asked questions

What do I have to do in Task 6?

Describing a graphic and forming hypotheses. Respond to the given situation and use the suitable phrases.

How much preparation time do I have?

Only short preparation time. Quickly note keywords and a structure, then speak freely into the microphone.
