Mismatched conclusion. This attempts to trigger a conditional chain, but mistakes a sufficient condition for a necessary one. It’s possible that Ruth lacks blooming flowers for a different reason. Also, the stimulus doesn’t trigger its conditional chain; it merely links sufficient conditions together.

Mismatched conclusion. This attempts to trigger a conditional chain, but mistakes a sufficient condition for a necessary one. It’s possible that Shawn lacks tomatoes for a different reason. The stimulus doesn’t trigger its conditional chain; it merely links two sufficient conditions together.

Mismatched premises and conclusion. This establishes that one of two things will occur (Maria will plant petunias or geraniums), and uses a pair of sufficient conditions to infer that one of two outcomes will therefore occur. The stimulus, however, establishes a conditional chain without making a concrete prediction about what will occur.

This forms a conditional chain. Li planting old roses is sufficient for her garden being beautiful, and her garden being beautiful is sufficient for impressing her neighbors. So it follows that Li planting old roses is sufficient for impressing her neighbors.

Mismatched premises and conclusion. This describes a necessary condition for Bryan’s trees to produce well, but then leaps to a conclusion about what Bryan will do based on what he desires. The stimulus, in contrast, merely links two sufficient conditions to form a chain and makes no concrete future prediction.
