Concept:Arranging jumbled sentences in a logical chronological and thematic order to form a coherent paragraph.
Explanation:The first sentence S1 states NSD was set up in 1959.
Sentence S follows logically because it tells that in 1975 NSD became autonomous — a clear chronological event after 1959.
Next, sentence R explains the objective of NSD: training in all aspects of theatre. This gives the purpose of the institution.
Then sentence Q describes the two-stage screening process for eligible applicants. This is a natural step after establishing the objective.
Finally, sentence P mentions that after admission, students undergo three years of training. This follows the screening process.
The sequence S, R, Q, P — that is SRQP — provides a smooth flow from history to purpose to admission procedure to training.
Other options like PQRS, QSRP, or RSPQ mix up this logical order, making the paragraph less coherent.
Answer:The correct sequence is SRQP, corresponding to option B.
