Passage Summary: Clarissa thinks science is useless without math and that observations only matter if they use numbers. Myungsook disagrees, arguing that you have to understand observations deeply before you can even try to turn them into numbers.

Reasoning: Clarissa argues that quantitative precision is a prerequisite for any valuable scientific observation, while Myungsook argues that qualitative exploration is a necessary first step that must precede quantification.

Analysis: The disagreement here is about the hierarchy and timing of mathematical application in science. Clarissa takes a hardline stance: if it's not quantitative, it's not worth your time. Myungsook counters by suggesting that the 'hardest' work happens before the numbers appear. To find the point at issue, use the 'Agree/Disagree' test: Clarissa would agree that an observation not stated in quantitative terms is worthless, whereas Myungsook would explicitly disagree, seeing the pre-quantitative stage as essential.
