This is only a 3-star difficulty question, but this question gave me a lot of trouble. The biggest question I had was the way the logic flows in the stimulus.

Particularly because if we do decide to phase out the practice of injecting antibiotics in farm animals, then we're negating the sufficient assumption of the Antibiotics -> Better meat yields relationship given in the first sentence. But if we negate the sufficient assumption, the rule become irrelevant. But the very last part of AC (E) makes it so that A ↔ MY because it's assuming that the only way to increase meat yields is by A. In other words, /A ↔ /MY ←s→ Farmers go out of business which makes perfect sense.

Not sure if this is the correct explanation but this is the only explanation I could come up with.

The key (albeit subtle) flaw is that the quality of the replication of an object has no bearing on the quality of the replication of that replica. To give a real life example, let's say Person A tried to imitate the Mona Lisa painting by drawing a simple line. Then Person B came a long and drew the same simple line. Although no one would say that what Person A drew is a good replication of the original painting, we could argue that what Person B drew is a perfect replication of what Person A drew. But then of course, the passage is saying because Person A didn't do a good job of replicating the original painting, Person B would also not be able to replicate what Person A drew, which is absurd.

But even then, I think many of the ACs fail to pass the first descriptive test. In other words, all of the wrong ACs actually draw on this idea of "replicating an original object." I think the closest would be (E) which says the second book is similar to the first book, but then just because something is similar doesn't mean it's the replica of that thing whereas AC (A) passes this test with the tape recording example. It also passes the second part of the test by employing the same flawed reasoning which JY explained in the video.

Although I got this question wrong, I love questions like this. What doesn't kill me makes me stronger :)

The moment I read Q7 and skimmed over all ACs I just skipped it. Went -1 on this passage in 6 minutes... I really think skipping is the way to go for questions like this.

I got a score of 166, and I'm just so, so happy and grateful. Thanks 7 Sage, and good luck to everyone else!!!!!
