RC Question 19 Explanation

QUESTION TEXT: Which one of the following describes a theory whose status …

DISCUSSION: The fourth paragraph discusses the modified gravity theory:

• It’s radical because it requires major changes to Einstein’s general relativity
• Despite being radical, it makes testable predictions

So an analogous theory should be radical/challenge something established, but still testable using observable evidence.

___________

1. The theory can be tested. This contradicts the second point.
2. It doesn’t rely on ad hoc adjustments. It predicts new consequences.
3. The modified gravity theory contradicts the dominant theory (general relativity). It doesn’t fit with it.
4. This describes refutation, not a radical new theory that’s testable.
5. CORRECT. This fits both points: radical revision and testability.
