Expression of Ideas practice question

A student took these notes for a report: • A study tracked bird populations in two neighborhoods over ten years. • Neighborhood A planted many native trees during that period. • Neighborhood B planted mostly non-native ornamental trees. • Bird diversity rose sharply in Neighborhood A but stayed flat in Neighborhood B.

The student wants to present the study's main finding about the effect of native trees on bird diversity. Which choice most effectively accomplishes this goal?

  1. A. Over ten years, one neighborhood planted native trees while the other planted ornamental ones.
  2. B. Bird diversity rose sharply in the neighborhood that planted native trees, while it stayed flat in the one that planted non-native ornamentals.Correct
  3. C. The study tracked bird populations in two neighborhoods for a decade.
  4. D. Native trees are often recommended for urban landscaping projects.

Answer: B. Bird diversity rose sharply in the neighborhood that planted native trees, while it stayed flat in the one that planted non-native ornamentals.

The main finding is the contrast in outcomes tied to the type of tree planted. Only B reports the diversity results for both neighborhoods and links them to native versus non-native planting. A and C describe the study's setup without its result, and D offers an unrelated general recommendation.

Why the other answers are wrong

A. Over ten years, one neighborhood planted native trees while the other planted ornamental ones.
This reports what each neighborhood planted — the study's setup — but omits the bird diversity results, which are the actual finding.
C. The study tracked bird populations in two neighborhoods for a decade.
This describes the study's design (two neighborhoods, ten years) and stops before the result the question asks you to present.
D. Native trees are often recommended for urban landscaping projects.
A general landscaping recommendation isn't in the notes and isn't a finding; the goal requires reporting the diversity outcomes the study measured.
