Expression of Ideas practice question

While researching a topic, a student has taken the following notes: - The Great Wall of China was built over many centuries. - Its sections, taken together, stretch roughly 21,000 kilometres. - Some sections are built of rammed earth rather than stone. - Parts of the wall can be seen from an aircraft.

The student wants to emphasise how long the Great Wall is. Which choice most effectively uses relevant information from the notes to accomplish this goal?

  1. A. Taken together, the wall's sections stretch roughly 21,000 kilometres.Correct
  2. B. The Great Wall was built over many centuries.
  3. C. Some sections of the wall are built of rammed earth.
  4. D. The Great Wall is long enough to be seen from the Moon.

Answer: A. Taken together, the wall's sections stretch roughly 21,000 kilometres.

Only choice A gives the wall's length.

Why the other answers are wrong

B. The Great Wall was built over many centuries.
Time taken to build isn't length.
C. Some sections of the wall are built of rammed earth.
Building material isn't length.
D. The Great Wall is long enough to be seen from the Moon.
The notes say parts can be seen from an aircraft, not from the Moon.
