Ecologist Dr. Liam O'Connor investigated the nesting habits of eastern bluebirds (*Sialia sialis*) in suburban parks. O'Connor hypothesized that eastern bluebirds prefer to build nests in artificial nest boxes rather than natural tree cavities when both options are available in the same territory. To test this hypothesis, O'Connor's team monitored several parks where equal numbers of suitable natural tree cavities and artificial nest boxes were present during the breeding season. Which choice, if true, would most directly support Dr. O'Connor's hypothesis?

  1. In the monitored parks, the vast majority of eastern bluebird pairs chose to construct their nests in artificial nest boxes rather than in natural tree cavities.Cevap
  2. B
    Eastern bluebirds in parks with artificial nest boxes fledged more offspring on average than did those nesting in parks with only natural tree cavities.
  3. C
    Almost all of the artificial nest boxes in the study remained unoccupied, while nearly every natural tree cavity was used by nesting eastern bluebirds.
  4. D
    Other bird species, such as house wrens, frequently competed with eastern bluebirds for access to both natural tree cavities and artificial nest boxes.

Cevap

In the monitored parks, the vast majority of eastern bluebird pairs chose to construct their nests in artificial nest boxes rather than in natural tree cavities.
The correct answer directly supports the hypothesis by showing that under conditions where both nesting options were equally available, the eastern bluebirds overwhelmingly chose the artificial nest boxes. This observation of actual nesting behavior directly aligns with the predicted preference.

Adım Adım Çözüm

1
Identify the ecologist's hypothesis in the passage.
Dr. O'Connor hypothesized that eastern bluebirds prefer nesting in artificial nest boxes over natural tree cavities when both are available.
Understanding the specific claim being tested is necessary to evaluate which evidence supports it.
2
Evaluate the experimental setup described.
The study set up a scenario where eastern bluebirds had equal access to both nesting options in the same territory.
This establishes the baseline conditions under which a preference can be observed.
3
Determine which finding directly demonstrates the hypothesized preference.
Evidence showing that bluebirds selected the artificial boxes over the natural cavities when both were available directly supports the preference hypothesis.
Selecting the option showing the actual choice of artificial boxes aligns the evidence with the hypothesis.
