Logic Breakdown

Passage Summary: These pesticides work great the first time you use them, but if you keep using them on the same field, the amount of crops you get starts to drop.

Reasoning: Hydrocarbon-based pesticides provide an immediate boost in crop yield on new fields, but continued use over time leads to a gradual decline in those yields.

Analysis: We are looking for a logical 'bottom line' to complete this thought. The evidence shows a pattern of diminishing returns: a short-term 'high' followed by a long-term 'low.' A successful completion will likely synthesize these facts to suggest that the long-term effects of these pesticides are detrimental or that their initial success is an unreliable indicator of their overall value.
