Each item consists of six sentences of a passage. The first and sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled as P, Q, R and S. You are required to find the proper sequence of the four sentences and markyour response accordingly on the Answer Sheet.
S1 :The dawn of the information age opened up great opportunities for the beneficial use of data.
S6 :To some, in this era of Big Data analytics and automated, algorithm-based processing of zettabytes of information, the fear that their personal data may be unprotected may conjure up visions of a dystopian world in which individual liberties are compromised.
P :But it is the conflict between the massive scope for progress provided by digital era and the fear of loss of individual autonomy that is foregrounded in any debates about data protection laws.
Q : It also enhanced the perils of unregulated and arbitrary use of personal data.
R : It is against this backdrop that the White Paper made public to elicit views from the public on the shape and substance of a comprehensive data protection law assumes significances.
S :Unauthorised leaks, hacking and other cyber crimes have rendered databases vulnerable.
The correct sequence should be

A

S Q R P

B

Q P R S

C

S R P Q

D
