The middle four sentences in each have been removed and jumbled up. These are labeled P, Q, R and S. You are required to find out the proper sequence of the four sentences and mark your response accordingly on the Answer Sheet.

S1 :Universities are peculiar institutions.
S6:It is the most important institution in the complex process of knowledge creation and distribution.
P:Traditionally elite institutions, the modern university has provided social mobility to previously disfranchised groups.
Q:The contemporary university stands at the centre of its society.
R:They have common historical roots yet are deeply embedded in their societies.
S:Established in the medieval period to transmit established knowledge and provide training for a few key professions, universities have become a primary creator of new knowledge through basic research.

The proper sequence should be 

A) P S Q R B) S Q R P
C) S P R Q D) R P S Q
 
Answer & Explanation Answer: C) S P R Q

Explanation:

The starting statement states about the universities being the peculiar institutions. Next statement would be talking about the establishment of such institutions. So, S would be the succeeding statement. Thus, the option (a) and (d) get eliminated. The continuing statement would be talking about the contribution of modern university. So, next statement would be P. This eliminates option (b) as well. Thus, the correct sequence is SPRQ.
