Study of human psychology reveals that feeling of guilt has a strong effect on the mind and this feeling is intensified when in seclusion. Hence, any criminal who is kept in solitary confinement for up to a month is likely to refrain from any criminal activity after his punishment is over.
Which one of the following, if true, most seriously weakens the conclusion above?
A. Solitary confinement is not the only way of making criminals feel guilty.
B. Solitary confinement is already in place in many countries of the world.
C. Many criminals who have not been given solitary confinement have refrained from further criminal activity
D. In some cases, criminals do not consider themselves guilty of their actions before solitary confinement.
E. There are some habitual criminals who commit crimes even when they feel guilty about their earlier actions.
As per the above question, feeling of guilt has a strong effect.. and then it goes on to say that Any criminal kept in Solitary confinement.
Question stem no where says that the Criminal who are feel guilty but makes a statement about Any Criminal, and hence if that Criminal (Mentions Some means any number between 1 to 100) doesn't even feel guilty than solitary confinement will have no impact on him and this weakens the argument.
Hence chose option D
Please let me know where did I falter in this approach?
