Concept:
- In sentence-ordering questions about a process, find the event that starts the whole sequence first.
- Then follow the natural order of steps: instructions given, work compared or planned, draft shown for approval, and finally the completed result.
- Look for words like 'final design' that clearly signal the last event in the sequence.
Step 1: Find the starting event.
E, 'The teacher asked his students to prepare a poster for a fashion campaign', is the trigger that starts the whole activity, so it comes first.
Step 2: Find what happens right after the assignment is given.
C, 'The students were given proper guidelines for the layouts', logically follows since guidelines are given before the students start working.
Step 3: Find the next stage of the work.
A, 'The students compared different poster layouts', comes next as the students explore options using the guidelines.
Step 4: Find the review and final steps.
D, 'A rough design was shown to the teacher', comes after the students settle on an approach, as they check it with the teacher.
B, 'Their final design used bold headlines and minimal text', is the concluding outcome, mentioning the 'final design', so it comes last.
Final Answer: E, C, A, D, B
