A team of researchers hypothesizes that converting grass lawns to native meadows in suburban yards increases the diversity of insect species, including pollinators, in those neighborhoods.
Which finding, if true, would most strongly support the team's hypothesis?
- A
Many pollinator species are in decline globally.
- Bcheck_circle
Suburban yards converted to native meadows recorded several times more insect species — including more pollinator species — than nearby yards left as conventional grass lawns.
- C
Some homeowners associations restrict lawn alternatives.
- D
Native meadows often require less watering than grass lawns.
Explanation
A directly tests insect species diversity in converted versus conventional yards. B, C, and D are tangential.
