Each of the following items in this section consists of a sentence, parts of which have been jumbled. These parts have been labelled as P, Q, R and S. Given below each sentence are four sequences namely (a), (b), (c) and (d). You are required to re-arrange the jumbled parts of the sentence and mark your response accordingly.
P: history of life
Q: evolutionary Biology is
R: forms on earth
S: the study of
The correct sequence should be
- ASPQR
- BQSPR
- CRPQS
- DPSQR
Explanation
The subject is 'evolutionary biology' (Q: 'Evolutionary biology is'), so Q must open the sentence and S ('the study of') must follow it — 'is the study of' is the natural predicate. P ('history of life') then says what is studied, and R ('forms on earth') completes the phrase 'life forms on earth'. This gives 'Evolutionary biology is the study of history of life forms on earth.' Hence (B) QSPR is correct.
