In Inference Q/s it is wise to stay within scope of the argument than assume new information for which there may not be substanial evidence
Understand the argument is key -
Drug Cos POV: Lets advertise direct to consumer - Why? More educated consumer. Interesting!
Author's POV: But these commericals dont tell anything on what the drugs do? (Why?) Cause if cos dont tell what drugs do, they have no compulsion to speak about side effects. Interesting!
This implies side effects may not be spoken yet in most commercials. How can you be an educated consumer without knowing both pros and cons. This defeats the initial commentary by Drugs Co.
Now lets go through the options
(A) does not leave consumers inadequately informed about the medicines in question - There is double negative so this option meams it leaves consumer adequately informed. Absolutely opposite to intended effect!
(B) is not truly designed to produce a more educated consumer - Yes
(C) boosts consumption of such medicines - No evidence - we are just assuming stuff
(D) is intended to have a direct impact on doctors rather than on their patients - No evidence - we are just assuming stuff
(E) is probably less effective than other forms of marketing used by drug companies - No evidence - we are just assuming stuff
