Difficulty: EasyAligning Data and Predictions with Viewpoints

Two students discuss how migratory birds navigate over long distances.

*Student 1* claims that birds navigate primarily by detecting the Earth's magnetic field (magnetoreception). According to this view, birds can navigate successfully regardless of visibility or geographical features.

*Student 2* claims that birds navigate primarily by recognizing visual landmarks, such as coastlines, rivers, and mountain ranges. According to this view, birds require clear visibility and familiar geographical features to remain on course.

A researcher conducted an experiment where a flock of migratory birds was tracked during an overcast night as they flew over a featureless ocean. The birds successfully maintained their standard migration route.

This experimental finding is consistent with the viewpoint(s) of which student(s)?

  1. Student 1 onlyAnswer
  2. B
    Student 2 only
  3. C
    Both Student 1 and Student 2
  4. D
    Neither Student 1 nor Student 2

Answer

Student 1 only
The experimental finding is consistent with the viewpoint of Student 1 only. Student 1 claims that birds navigate using the Earth's magnetic field, allowing successful navigation regardless of visibility or geographical landmarks. The experiment occurred under overcast skies (no celestial visual cues) over a featureless ocean (no landmarks), yet the birds navigated successfully. This aligns with Student 1's prediction and contradicts Student 2's claim that visibility and landmarks are required.

Step-by-Step Solution

1
Analyze the conditions of the experiment described in the passage.
The experiment took place during an overcast night (no visibility of stars or sky cues) over a featureless ocean (no coastlines, rivers, or landmarks).
To determine what visual or spatial cues were available to the birds during their flight.
2
Evaluate Student 1's hypothesis against these conditions.
Student 1 proposes that birds use the Earth's magnetic field and can navigate successfully regardless of visibility or landmarks. This is consistent with the birds successfully maintaining their route.
To see if the experimental outcome supports Student 1's claim.
3
Evaluate Student 2's hypothesis against these conditions.
Student 2 proposes that birds require clear visibility and visual landmarks. Since both were absent, Student 2's hypothesis predicts that the birds would not be able to navigate successfully, which contradicts the experimental outcome.
To see if the experimental outcome supports Student 2's claim.
