Answer» The use of the phrase ‘causes and their’ is appropriate with ‘effects’ as ‘CAUSE and effect’ is an idiom. This makes option 1 and 4 as the prospective correct answers. This now, the SENTENCE forms as ‘The causes and their effects belong to the..’, which can be MEANINGFULLY followed by ‘ONE order’ and not ‘in the same series’. This makes ZYX as the correct sequence.$
