Concept:
- In para jumble questions, first look for a clause that can stand as the main idea, and a clause that gives the reason, usually starting with 'because'.
- A 'because' clause can open a sentence if it is followed by a comma and the main statement, so check both possible positions before deciding.
- Read the assembled sentence fully once to check it flows and makes complete sense.
Step 1: Look at the four parts.
C says 'because the aesthetics of design', D says 'is highly subjective and personal', A says 'the world of fashion', B says 'can often prove exacting'.
Step 2: Join the reason clause first.
C and D fit together as 'because the aesthetics of design is highly subjective and personal', a complete reason clause.
Step 3: Join the main clause next.
A and B fit together as 'the world of fashion can often prove exacting', a complete main statement.
Step 4: Combine both clauses and read the full sentence.
'Because the aesthetics of design is highly subjective and personal, the world of fashion can often prove exacting' reads smoothly and makes complete sense.
This gives the order C, D, A, B.
Final Answer: C, D, A, B
