In this section, each item consists of six sentences. The first and sixth sentences are marked as S1 and S6. The four sentences between S1 and S6 have been jumbled up and labelled as P, Q, R and S. This is followed by four options, each suggesting a sequence of sentences. Identify the most appropriate option and mark your response on the Answer Sheet accordingly.
S1: Systematic and ceaseless efforts are being made to tap scientifically the abundant solar energy available in the country.
S6: Installation of solar thermal systems and devices has helped to save or generate energy to the extent of 350 kWh per annum.
P: These include cooking, water heating, water desalination, space heating, etc.
Q: A large number of applications in the area have already become commercial.
R: Efforts are also afoot to develop economically viable solar collectors for high temperature applications.
S: A simple and common mode in solar energy utilization is solar thermal conversion. The proper sequence should be
- AQSRP
- BQPRS
- CSQPR
- DRQSP
Explanation
‘S’ will be the first part of the given sequence as it talks about one of the common modes in solar energy utilisation, that is, solar thermal conversion. ‘Q’ will follow next as it talks about the commercialisation of large number of applications. ‘P’ will follow next as ‘these’ is used in the context of ‘large number of applications’ in Q. ‘R’ will follow next as it further talks about the ‘efforts’. Hence, SQPR is the correct sequence. Thus, option (c) is correct.
