Q25. Below are six possible summaries for your presentation:
– Summary 1: “The data revealed a moderate positive correlation between age and recycling frequency. While 72% of students reported recycling paper regularly, only 39% reported recycling plastic.”
– Summary 2: “Analysis showed notable differences in recycling habits by material type, with paper being most recycled and plastic least recycled.”
– Summary 3: “Older kids recycled more than younger ones. Paper was the most recycled item- plastic got forgotten a lot.”
– Summary 4: “Student responses showed positive environmental habits overall, though participation varied by waste type.”
– Summary 5: “A lot of students said they recycle. Some didn’t answer every question, so we couldn’t figure out everything.”
– Summary 6: “We asked more than 300 students about recycling. Most said they recycle paper, but way fewer recycle plastic.” Which communication style is the best fit for Group A (data scientists) and Group B (12-year- olds), respectively? Select the best answer.

Q30. You are given two lists representing daily page views and sign-ups on a website:
views = [120, 130, 128, 700, 115, 123, 119, 680, 122]

– print the value only if no error occurs,
– and always print a final message after execution.
