While researching a topic, a student has taken the following notes:
  • A 2022 study analyzed geotagged social media posts to assess the effect of parks on happiness in 25 US cities.
  • The happiness benefit of a city’s parks was the numeric difference between the calculated happiness scores of posts made in parks and posts made elsewhere.
  • A benefit above 0 indicates a positive effect.
  • The park happiness benefit in San Francisco, California, was greater than 0.10.
  • The park happiness benefit in Washington, DC, was greater than 0 but less than 0.10.
  • The average happiness benefit of parks across all cities was 0.10.
The student wants to make a generalization based on the study’s findings. Which choice most effectively uses relevant information from the notes to accomplish this goal?
A
Geotagged social media posts were analyzed for expressed happiness in both San Francisco and Washington.
B
Though it can vary from city to city, the overall effect of parks on happiness is a positive one.
C
San Francisco’s parks had a positive effect on happiness, but this was not true of Washington’s parks, which had a below-average effect.
D
By comparing the happiness scores of posts made in parks and posts made elsewhere, the study determined the effect of parks on happiness.
