Q2 [2]
Working: 20+35+60+120+200+250+230+180+140+90+45+25 = 1395 mm.
Answer: 1395 mm.
Teaching: Add all 12 monthly values. Show sum clearly.
Marking: 1 for working, 1 for correct total.

Q3 [2]
Answer: Temperature is high throughout the year, ranging from 26.5°C to 28.5°C with little variation (about 2°C range).
