(a) The paragraph should begin with the sentence E as it talks about the factors influencing forecast which sets the sequence for the rest of the paragraph. So options (c) and (d) are rejected. Statement E is followed by Statement A as it details the factors. Statement C is in line of sequence with ‘another way’ in it classifying the factors given in earlier statements. DB is proper subsequence as one is having ‘macro’ and other ‘micro’ factors respectively. So proper sequence is (E-A-C-D-B).
