Expression of Ideas practice question

While researching a topic, a student has taken the following notes: - Lake Baikal is in Siberia, Russia. - It is the deepest lake in the world, at about 1,600 metres. - It holds about a fifth of the world's unfrozen fresh water. - It is home to the only freshwater seal species.

The student wants to introduce Lake Baikal to an audience unfamiliar with it. Which choice most effectively uses relevant information from the notes to accomplish this goal?

  1. A. Lake Baikal, in Siberia, is the world's deepest lake and holds about a fifth of its unfrozen fresh water.Correct
  2. B. Lake Baikal is about 1,600 metres deep.
  3. C. The only freshwater seal species lives in Lake Baikal.
  4. D. Lake Baikal is the largest lake in Russia by surface area.

Answer: A. Lake Baikal, in Siberia, is the world's deepest lake and holds about a fifth of its unfrozen fresh water.

Where it is and why it matters — choice A introduces the lake.

Why the other answers are wrong

B. Lake Baikal is about 1,600 metres deep.
A depth alone doesn't say where or what the lake is.
C. The only freshwater seal species lives in Lake Baikal.
An interesting detail, but no introduction.
D. Lake Baikal is the largest lake in Russia by surface area.
The notes say nothing about surface area.
