SAT question 25b70215 (Command Of Evidence)

Question

Researchers Carolina Laura Morales and Anna Traveset gathered data about flowering plants growing alongside each other in various locations. In each case, the researchers identified one plant as a “target species” and a nearby plant as a “neighboring species.” The researchers then calculated a positive or negative value to show how the neighboring species affected pollinator visits to the target species. One example of a neighboring species with a negative effect value is the Which choice most effectively uses data from the table to complete the example?

College Board · Accepted Answer

The correct answer is B. Choice B is the best answer because it most effectively uses data from the table to complete the example of a neighboring species that has a negative effect value. The table lists neighboring species, target species, and effect values. The table shows that only one neighboring species, the common dandelion, has a negative effect value (−0.6254).

Effect of Neighboring Species on Pollinator Visits to Target Species
Neighboring species	Target species	Effect value
Virginia spring beauty	star chickweed	$0.4853$
Himalayan balsam	marsh woundwort	$0.7905$
common dandelion	cat’s ear	−0.6254
