LSAT 104 | Section 3 | Reading Comprehension: Q18

RC Question 18 Explanation

DISCUSSION: The first alternative is vaguely worded. Basically, it’s possible that pigeons have an internal system that measures where they’ve traveled  and how far.

Researchers don’t know how the system could work. It could depend on magnetism, watching the movement of the world around you, an inner sense of motion, etc.

___________

1. Lines 29-33 say that we still need to do an experiment that tests all of these factors at once.
2. There are plenty of theories to explain how pigeons could track displacement: magnetism, vision, etc.
3. CORRECT. Lines 16-29 describe the experiments that have failed to support the hypothesis. Lines 29-33 show that we need to do one final experiment to completely disprove the hypothesis.
4. Lines 20-22 and 28-29 show that both types of experiment have shown no evidence that pigeons can track their movement.
5. Lines 29-33 are clear that a properly conducted experiment could disprove the hypothesis.
