Which of the following would be the FOURTH statement after rearrangement?

The correct rearrangement is ‘RSTQP’. ‘R’ introduces the subject of the paragraph which is the types of geothermal power plants. Other sentences elucidate the types of geothermal power plants. In ‘R’, the first type of geothermal power plants is mentioned as ‘dry steam’. ‘S’ provides information about the ‘Dry steam’. So, ‘S’ should be the second sentence. ‘T’ provides information about the ‘Flash plants’ which is mentioned at second place in ‘R’. So, ‘T’ should be the third sentence of the paragraph. ‘Q’ takes the idea introduced at ‘T’ forward. ‘Q’ informs us about what the steam, which is produced in ‘T’, do. So, ‘Q’ should be the fourth sentence of the paragraph. ‘P’ provides information about ‘binary plants’ which is mentioned at third in ‘R’ as the type of geothermal power plant. So, ‘P’ should be the Fifth sentence of the paragraph.
