A field biologist measured the average tail length (in cm) of four lizard species: Species K, 7.2; Species L, 9.1; Species M, 5.4; Species N, 12.6. The biologist proposed that Species N exhibits an unusually long tail compared to its relatives. To support this, the biologist could cite ______
Which choice most logically completes the text using the data above?
- A
the average tail length across all four species.
- B
Species L's 9.1 cm tail.
- C
Species K's 7.2 cm tail.
- Dcheck_circle
Species N's tail of 12.6 cm—more than twice that of Species M and clearly longer than the other species.
Explanation
The claim is N's tail is unusually long. Choice A directly demonstrates this by comparing N's value to the others, including a 2x ratio versus Species M.
