Reading the passage
The second theory would substantially revise an established account of gravity. It isn't merely a new observation that fits the old theory unchanged. It also has consequences that could be checked in our own solar system.
What we’re looking for
So the analogy needs both features: a radical change to an established theory and an available way to test the new proposal.
Working the answers
- A
This theory cannot be confirmed or disconfirmed by the available particulars. Our gravity proposal has potentially testable consequences nearby. A's sweeping scope doesn't compensate for that opposite testing status.
- B
The economic theory preserves its basic claim by treating apparent violations as special cases. Our proposal changes the established theory of gravity rather than explaining away the unexpected findings while leaving it intact.
- C
Compatibility with the dominant theory means no revision is needed. The astronomical setting is a surface match; the relationship to the existing theory is wrong.
- D
Here a study has already proved an existing classification wrong. The gravity proposal remains a theory with possible tests ahead of it, not a completed empirical refutation.
- ECorrect
The established theory of evolution corresponds to the established account of gravity. The new proposal would require major modifications, yet observable phenomena can confirm or disconfirm it. That preserves both the radical change and the practical possibility of testing it.
