Question 1

A city habitat team tested several small changes to public planting sites. The displays report separate parts of the pilot: before-and-after pollinator counts at three parks, visits to native and introduced flowers, weekly seedling survival, shade and soil temperature, and moisture readings for two treatments. The team expected added shade to help soil retain moisture. Because locations were not randomly assigned to every condition, the report treats the patterns as evidence for further testing rather than proof that any one treatment caused every difference.

The team predicted that added shade would help soil retain moisture. Which choice is supported by both that prediction and the displayed results?
Average soil moisture by treatment
TreatmentBeforeAfter
Shaded2434
Unshaded2527

Average soil moisture by treatment: Shaded, 24, 34; Unshaded, 25, 27.
