Passage Summary: Since life's problems are messy and cross over different subjects, students should learn through mixed-subject classes rather than separate ones.

Conclusion: Schools should replace individual academic discipline courses with interdisciplinary courses.

Reasoning: Most real-world problems cannot be solved by using knowledge from a single academic field in isolation.

Analysis: The educator assumes that the best way to prepare for multi-disciplinary problem-solving is to learn in a multi-disciplinary environment. This is a significant leap; one could argue that you need a deep, isolated understanding of math and physics separately before you can effectively combine them to build a bridge. To strengthen this argument, look for an answer that confirms interdisciplinary courses are actually more effective at teaching students how to apply knowledge to real-world problems than traditional, single-subject courses are.
