Directions: The following sentences form a paragraph. The second and fourth sentences of the paragraph are given. The rest are numbered as A, B, C, D, and E. These five parts are not given in their proper order. Arrange them in the correct order to make the paragraph meaningful and then answer the questions given below.
A. The relative timing of these launches may be a coincidence but it is heartening because the ratio of scientific to technological missions ISRO has launched is skewed in favour of the latter, at the expense of research in the sense of discovery. 2. ISRO launched the XPoSat, in a two-part mission, onboard a Polar Satellite Launch Vehicle (PSLV) on its C58 flight on January 1.
B. The XSPECT payload, by ISRO’s U.R. Rao Satellite Centre, will study X-rays of energy 0.8-15 keV and changes in continuous X-ray emissions. 4. Those science-oriented missions have all been exceptional in their own right.
C. Two missions the ISRO has launched in the five months since its success with Chandrayaan-3 have both been scientific: the Aditya L-1 space probe to study the sun and the X-ray Polarimeter Satellite (XPoSat) to study polarised X-rays emitted in astrophysical phenomena.
D. For example, XPoSat is only the second space-based experiment to study X-ray polarisation, and at higher X-ray energies than the other, NASA’s Imaging X-ray Polarimetry Explorer.
E. Its POLIX payload, realized by the Raman Research Institute, will track X-rays in the 8-30 kilo-electron-volt (keV) energy range and observe emissions from around 50 sources in five years.

Correct answer
B
Why this answer is correct
The correct answer is 'B.'
Key Points
- The correct sequence or order of the segments after rearrangement is C2A4DEB.
- The sentence 'C' is independent of any other sentence as it introduces the two missions the ISRO has launched in the five months since its success with Chandrayaan-3.
- The second sentence gives further information about the XPoSat.
- Sentence A will come after the second sentence as it talks about the relative timing of the launches of the XPoSat.
- The fourth sentence says the ISRO's science-oriented missions have all been exceptional in their own right.
- Sentence D will come after the fourth sentence as it gives an example to prove the fourth sentence true as it says XPoSat is only the second space-based experiment to study X-ray polarisation, and at higher X-ray energies than the other, NASA’s Imaging X-ray Polarimetry Explorer.
- Sentence E will come after D as it further gives information about the XPoSat that its POLIX payload, realized by the Raman Research Institute, will track X-rays in the 8-30 kilo-electron-volt (keV) energy range and observe emissions from around 50 sources in five years.
- The sentence 'B' is the concluding or seventh sentence as it talks about the XSPECT payload, by ISRO’s U.R. Rao Satellite Centre, which will study X-rays of energy 0.8-15 keV and changes in continuous X-ray emissions.
Hence, the correct answer is option 1.
