from what I understand, B doesn't engage with the causation chain while A does.

Yeah I have the same feelings. But I do understand that by read silently here, they are referring to not reading out loud, not making no sounds by expressing.

wish we had this a few weeks earlier 😭 august lsat tomorrow and reading comp is holding me down

I had this one right but only last second did I change my answer to C…

I also ended up with C but I initially chose A.

The archeologist could have many reasons to why they needed to remove the mosaics. I think A is basically cementing the reasoning that they only needed the archeological information and nothing else from the mosaic which then concludes they didn’t need to remove them.

I think C just doesn’t really improve anything since it’s similar to the premise.

C is wrong because it doesn’t matter if they consume the same amount of fat as people who did not decrease red meat. If you think about it, if both groups consume the same amount of “other fat” then one group consumes less fat through red meat, they will actually have a total lower amount of fat consumed.

For example:

Group 1: 50g fat + 10g fat (red meat) = 60g

Group 2: 50g fat + 0g fat (red meat) = 50g

So this doesn’t explain why group 2 would have more but instead would support the first part. Therefore, answer C doesn’t explain why group 2 would actually have more fat consumed.
