Recently, photons and neutrinos emitted by a distant supernova, an explosion of a star, reached Earth at virtually the same time. This finding supports Einstein’s claim that gravity is a property of space itself, in the sense that a body exerts gravitational pull by curving the space around it. The simultaneous arrival of the photons and neutrinos is evidence that the space through which they traveled was curved.
Which one of the following, if true, would most strengthen the reasoning above?
(A) Einstein predicted that photons and neutrinos emitted by any one supernova would reach Earth simultaneously.
(B) If gravity is not a property of space itself, then photons and neutrinos emitted simultaneously by a distant event will reach Earth at different times.
(C) Photons and neutrinos emitted by distant events would be undetectable on Earth if Einstein’s claim that gravity is a property of space itself were correct.
(D) Photons and neutrinos were the only kinds of particles that reached Earth from the supernova.
(E) Prior to the simultaneous arrival of photons and neutrinos from the supernova, there was no empirical evidence for Einstein’s claim that gravity is a property of space itself.

EXPLANATION FROM Fox LSAT
This makes absolutely no sense to me. Which is okay. If the argument makes no sense, that’s not because you’re not smart. It’s because the argument just doesn’t make any **** sense. Got that?
Let’s rearrange the evidence and the conclusion, to see where the gap(s) are:
- Premise: Photons and neutrinos reached Earth simultaneously.
- Premise: The simultaneous arrival of photons and neutrinos is evidence that the space through which they traveled is curved.
- Premise: Einstein claimed that gravity is a property of space itself.
- Conclusion: Therefore Einstein was right.
There’s a gap here, which we know because the argument doesn’t make sense. Since we’re asked to strengthen the reasoning, let’s try to find an answer that tends to fill that gap.
A) I suppose that if Einstein predicted this outcome in advance, then that tends to support the idea that Einstein knew his ****. But it doesn’t necessarily support the idea that “gravity is a property of space itself,” which is the conclusion of the argument. So I doubt this is our answer.
B) Since the photons and neutrinos did arrive simultaneously, this answer choice would actually prove that gravity is a property of space itself. (It’s the contrapositive. If it’s true that if gravity is a property of space itself —> then photons and neutrinos arrive at a different time, then it’s also true that if photons and neutrinos arrive at a different time —> then gravity is a property of space itself. This answer, if true, would make Einstein conclusively right. So this is almost guaranteed to be the correct answer.
C) Nah, this would actually weaken Einstein’s argument. We needed to strengthen.
D) This is just irrelevant. What do other particles, or the lack thereof, have to do with anything?
E) Nah. The lack of prior evidence certainly doesn’t strengthen Einstein’s case.
The answer is B, because if it’s true then Einstein is proven correct.
Again, this was a tough question. Don’t kill yourself on it (or on any single question on the LSAT). Move on and try another one.

The question is asking which option most strengthen the reasoning that the simultaneous arrival of photons and neutrinos supports Einstein’s claim that gravity is a property of space itself.
Key point: If Einstein is wrong, photons and neutrinos should not arrive together.
(A) Predictive but doesn’t show why the arrival supports the claim – eliminate.
(C) Contradicts the evidence – eliminate.
(D) Irrelevant, doesn’t address Einstein’s claim – eliminate.
(E) Background info only, not strengthening – eliminate.
Answer: (B)
