Question

read these two excerpts from the text. level ii and level iv would cover different topics in physics class than level i. this is because
a the laws of physics would be different.
b kids who are 12 would go to different schools.
c dragons and superheroes would exist.
d the physics classes would take place in outer space.
excerpt 1
level i: infinite galaxies, earths, and copies of you.
tegmark: if space is infinite and uniform, meaning it’s full of stuff and not just an empty vacuum, then anything that can happen, will happen. but we don’t know the chances for dragons and superheroes. if something’s against the laws of physics, then it wouldn’t happen anywhere.
in level i parallel universes, if you’re 12 years old and in school, you’d learn about gravity in all physics classes on all worlds. but in history class, you’d learn that we just had world war 5 or something.
excerpt 2

Explanation:

The excerpt states that in Level I parallel universes, physics classes teach the same gravity (same physical laws) across all worlds. Since Level II and IV cover different physics topics, this implies their physical laws differ from Level I. Options B, C, D are irrelevant: B refers to school placement, C is about impossible physics-violating entities, D is about class location, none of which relate to differing physics topics.

Answer:

A. the laws of physics would be different.
