All sages provide both wisdom and inspiration. Since Dasha’s speech contained wisdom and greatly inspired her audience, Dasha is a sage.
Which one of the following points out the flaw in the argument above?

Does anyone else beside sages provide wisdom and inspiration?

The way I remember this subject:
hypothetical statement  if a cow, then a mammal
converse  if mammal, then a cow (not necessarily true)
inverse  if not a cow, then not a mammal (not necessarily true)
contrapositive  if not a mammal, then not a cow (true)
now here
statement  if sage, then wisdom
converse  if wisdom, then sage (not necessarily true) (this is it!)
inverse  if not sage, then not wisdom (not necessarily true)
contrapositive  if not wisdom, then not sage (true)
Here we have the converse, so not necessarily true. 
Alternately draw Venn diagrams as Ms. Sue did in her head.
