Question Type:
Strengthen
Stimulus Breakdown:
Amber is valuable when it has something living in it, so people fake it. When they do, they include a normal-looking insect. So be wary of amber with normal-looking insects - it's much more likely to be fake than other amber!
Answer Anticipation:
The conclusion compares two sets of amber - those with normal-looking insects, and those without normal-looking insects (which includes weird-looking insects, plants, dirt, nothing, etc…). However, we only learn that forgers fake amber by including normal-looking insects - we don't learn what actual amber contains! In order to draw this comparison, we need to know that normal amber doesn't have normal-looking insects in it.
Correct answer:
(E)
Answer choice analysis:
(A) Out of scope. While this may explain why there's a lot of fake amber out there, it doesn't impact an argument about the authenticity of normal-insect amber vs. other amber, since this answer would apply equally to both.
(B) Out of scope. Size matters not, young padawan.
(C) Out of scope. This answer suggests a reason to use insects instead of plants when forging amber, but it doesn't let us know why normal-insect amber is more likely to be fake than other amber.
(D) Out of scope. This answer gives us a reason to think that amber wouldn't be tested for authenticity, but, again, it doesn't touch on the difference between the normal-insect amber and other amber, as far as relative levels of forgery.
(E) Winner! This answer choice talks about weird-insect amber. According to this answer, insects that are naturally encased in amber (i.e., not through forgery) won't look normal. This gives us a reason to believe that normal-insect amber is a forgery, as compared to weird-insect amber.
Takeaway/Pattern: When the LSAT brings up a point and then uses it to compare two things, the initial point itself has to apply to both things being compared. This argument is akin to saying, "Dave is tall, therefore he's taller than Matt."
