I usually take a long time on questions, but this one threw me for a loop. When we just worked on very formal logic training regarding PSA/Principle, this one was a mess. I diagrammed and looked at Some Before All and Most Before All. I finally got the answer right due to hunting for my answer and finding, via grammar parsing, that every other answer choice was dumb.

This might not be an accurate question, or a question at all, but I thought to myself after two minutes that I should be diagramming, then diagrammed for a minute, and stared at my diagram for 30 minutes trying to put puzzle pieces together for some form of a logical argument I could make.

I realized that the stimulus gives me an easy out, that if both pools contain the same amount of stuff, then the pool that contains the more water (or more etching tools that act as engraving tools) then logically it follows that more etching tools will be used as engraving tools than not. Yea, just giving my feedback on this question that was superbly tough for me.

@Sagacious_Saxon0424 I believe I put the same answer as you and OP—framing the comparison around their ability to detect planets outside their solar system. But after watching the explanatory video and thinking on it more, I realize that “detecting planets outside the solar system” is actually more of a conclusion we draw from the level of sophistication of each instrument.

In other words, the real point of comparison in the stimulus seems to be how sophisticated the instruments are—not directly their ability to detect planets. That ability is just evidence of one being more advanced than the other. Definitely a subtle distinction, but a helpful one for these kinds of comparative reasoning questions.
