Directions: Select the most appropriate filler(s) for the blank(s) such that the sentence makes coherent sense.

The methods of ____________ the criminals used in the medieval world can ____________ even the most hardened of policemen of the modern world.

Let's find the correct answer by POE: 'eradicating' in option (2) is ruled out as you can't eradicate criminals. 'resuscitating' in option (3) refers to revive or revitalize someone apparently dead, which is off the track, hence ruled out. On the same lines, 'admonishing' (to caution against specific faults; warn) in option (5) is ruled out. Now let's consider pair words of options (1) & (4) for the second blanks. Policemen of the modern world can't feel the agony (anguish), instead they would be shocked after knowing these methods. Hence, (4) is the answer.
