The best sequence is:
ii, i, iii, iv
iv, i, iii, ii
iv, iii, ii, i
iii, i, iv, ii
Option (iv) a general statement serves as the introductory statement to the paragraph correctly. Option (iii) elaborates the fact and opens up further information in option (ii). Option (i) comparing the past with the recent development serves as the concluding sentence.
iv, iii, ii, i is the correct option.
