Studies of Cougar Population Density

Study authors	Location	Methods	Study area (square kilometers)	Maximum density (cougars per 100 square kilometers)
Ross Clarke	British Columbia (Canada)	radio-collar tracking	3,045	0.72
Veronica A. Quiroga et al.	Argentina	regular camera trapping	1,882	1.26
Richard A. Beausoleil et al.	Washington (United States)	biopsy darting	7,939	2.40
David M. Choate et al.	Utah (United States)	helicopter surveying	1,300	10.24

Studies of the population density of cougars (Puma concolor) have yielded a range of results, which may in part reflect differences in the effectiveness of the methods that researchers have used in their studies. For example, the difference between the maximum population density reported by Ross Clarke and that reported by David M. Choate et al. might be artificially large if the use of __________

Which choice most effectively uses data from the table to complete the example?

helicopter surveying underestimates the density of cougars.

helicopter surveying is more common in Utah than the use of radio-collar tracking is.

radio-collar tracking underestimates the density of cougars.

radio-collar tracking is impractical outside of British Columbia.
