<pre>

    During the scientific process, deductive reasoning is used to reach a logical true conclusion. Another type 
    of reasoning, inductive, is also used. Often, people confuse deductive reasoning with inductive reasoning, 
    and vice versa. It is important to learn the meaning of each type of reasoning so that proper logic can be identified.

which nicely describes the subject.




My personal opinion is that learning this subject is interesting by itself,


but solving such problems as presented in your post, &nbsp;gives &nbsp;NOTHING.



Simply a way to kill the reader's time for nothing . . . 



Therefore, I consider submitting such posts as an unfriendly action . . . 



You may kill as much of your time as you want - it is your right.

But it is not a good style to impose such quasi- and pseudo-"problems" to others . . .
