Craft and Structure practice question

Text 1 Any estimate of an animal population from tracks in snow, biologist Karin Lund cautions, must account for the fact that a single animal can leave many trails in one night. Text 2 Rangers counted 60 sets of lynx tracks across the reserve after a fresh snowfall and reported a population of 60 lynx.

Based on the texts, how would Lund most likely respond to the rangers' report?

  1. A. By pointing out that 60 trails could have been made by far fewer than 60 lynx, so the figure is probably too high.Correct
  2. B. By agreeing that the reserve holds exactly 60 lynx.
  3. C. By arguing that snow is useless for counting animals.
  4. D. By suggesting the count is too low.

Answer: A. By pointing out that 60 trails could have been made by far fewer than 60 lynx, so the figure is probably too high.

One animal, many trails: the count of trails overstates the count of animals.

Why the other answers are wrong

B. By agreeing that the reserve holds exactly 60 lynx.
Text 1's caution argues against taking the figure at face value.
C. By arguing that snow is useless for counting animals.
Lund says estimates must account for the issue, not that they are useless.
D. By suggesting the count is too low.
The bias runs toward overcounting.
