Reading the passage
Look at the kind of explanation the physicists are seeking: explain physical reality through the characteristics and interactions of its smallest components. For an analogy, we want a theory that approaches a larger whole through the properties and interactions of its individual units.
What we’re looking for
The author questions how far that approach can take us, but we still need to identify the approach accurately before matching it.
Working the answers
- A
This explains plants through descent from earlier species. An account of historical origins doesn't match explaining a system through the characteristics and interactions of its present components.
- B
This contrasts the predictability of local and global weather. It doesn't describe explaining the larger system in terms of its smallest constituents. Its permanent prediction limit also isn't the defining feature of the proposed theory of everything.
- C
This excludes context from literary interpretation. The physics theory isn't described as deliberately ignoring outside information; it focuses on the fundamental particles and interactions making up physical reality.
- DCorrect
Individual consumers and producers play the role of subatomic particles. Their characteristics and interactions are used to explain economic activity, just as the physics theory uses particles' characteristics and interactions to explain physical activity. The matching relationship is whole-system explanation through individual components.
- E
Shared structures across different languages give us a resemblance among systems. The proposed physics theory instead explains physical reality through its components. There is no corresponding comparison among multiple systems here.
