I read this as there is no affect on the SHARES, but there was an affect on the overall market size. For example, one company might hold 50% of the market, and still hold 50% if sales descrease, therefore the market contracted, but that company's share did not.
Aside from that, none of the other choices are supported by the statements at all.
A) we don't know anything about what happens when a product is superior, nor does the stimulus discuss when market shares actually do increase
the stimulus says that comparative advertisements are good for markets bag aren't increasing, but doesn't say ONLY markets that aren't increasing
C) stimulus says nothing about retaliation
E) stimulus says nothing about long term gains or customers verifying claims.
