Klein: The fact that the amount of matter that we have found in our galaxy is only one-tenth of what Einstein's theory predicts gives us good reason for abandoning his view.

Speaker 1 Summary
Klein argues toward the implied conclusion that we should abandon Einstein’s theory. This is the conclusion indicated by Klein’s premise: that the fact that we’ve found much less matter in the galaxy than Einstein predicted justifies abandoning Einstein’s theory.
Speaker 2 Summary
Brown argues that instead of abandoning Einstein’s theory based on this inconsistency, we should instead believe that most of the matter in our galaxy hasn’t been found yet. In support, Brown points out that Einstein’s theory has had great successes (suggesting that one inconsistency isn’t enough to justify abandoning it).
Objective
We need to find something that Klein and Brown disagree about. Their disagreement is over whether we should abandon Einstein’s theory.

On the basis of their ███████████ █████ ███ █████ ███ █████████ ██ ███████████ ████ ███ █████ ██ █████ ███ ██ ███ █████████ ███████████
a
Scientists have found ████ █████████ ██ ███ ██████ ████ ██████████ ██████ █████████
Both speakers agree that this is true. Klein directly makes this claim. Brown doesn’t refer to this inconsistency explicitly, but talks about what we should believe based on this fact, indicating an agreement that it’s true.
b
Einstein's theory has ████████ ████ ██████████
Brown agrees with this, but Klein doesn’t state an opinion. Brown directly makes this claim. Klein just doesn’t say anything about the successes of Einstein’s theory, so we can’t know what Klein thinks.
c
It is possible ██ █████████ ███ ██████ ██ ██████ ██ ███ ██████ ███████ ███████ ██ ██████████ ███████
Neither speaker makes this claim. The discussion isn’t about how to determine the amount of matter in the galaxy, it’s about whether the observed amount of matter justifies abandoning Einstein’s theory.
d
The failure to ████ ███ ██ ███ ██████ █████████ ██ ██████████ ██████ ██████ ████ ██ ██ ███████ ███
Klein agrees with this, but Brown disagrees, making this the point of disagreement. Klein thinks that because of the inconsistency between the theory’s prediction and our observations, we should abandon the theory. Brown thinks we should look for more matter instead.
e
Scientists are able ██ ██████████ █████ ███ ██████ ██ ██████ ████ ███ ████ █████ ██ ███ ███████
Both speakers most likely agree with this. Neither speaker disputes that scientists know how much matter we’ve found. Also, this would have to be the case to accurately compare our findings with Einstein’s theory’s predictions.
