If half the nation suffers from depression, then if either the insurance companies have their way or the psychiatrists have their way, then everyone will be taking antidepressant drugs. If either half the nation suffers from depression or sufferers want a real cure, then it is not the case that everyone will be taking antidepressant drugs. Half the nation suffers from depression.

Follows are the solution to this question:

Explanation:

H = It is the half of nation is depressed  

J = It is the Insurance, which is provide by the way.  

P = It is the phychiatris way  

E = An antidepressant drugs, which can be used by everyone  

w = The patients want real treatment

Symbolic form can be defined as follows:    

[tex]H ((IVP) \varepsilon ) \\ (H V W) (\varepsilon )\\ H[/tex]

Substance: (IVP)  

The evidence:  

[tex]i). H \supset ((IVP)\supset \varepsilon ) \\ii). (HVW) \supset \wedge \varepsilon \\iii). H \\iv). (IVP) \supset \varepsilon [ 1,3 Modus Porers] \\v). HVW [ 3 , adddition] \\vi). \wedge \varepsilon [2, 5 mp] \\vii). \wedge (IVP) [4,6 Modus tollens][/tex]

So it's true that conclusion.  

[tex]\left\begin{array}{ccc}mp&addition&mt\\p \ \ \ \ q&p&p\ \ \ \ q\\\frac{p}{q} & p \vee q & \frac{ q}{p}\end{array}\right[/tex]
