Question 7

Step1: Identify midnight temps

List 12:00 midnight temps: 24°C, 24°C, 17°C, 22°C, 15°C, 23°C, 25°C.

Step2: Find the minimum

Among these, the lowest is 15°C.

Analyze trends: Category 1 (1 - 100g): 7256→6617→8470→3975 (fluctuates but overall?); Category 2 (101 - 1000g): 1217→886→370→169 (decreasing); Category 3 (1001 - 3000g): 230→199→72→19 (decreasing). Option B says all categories decline, which matches the decreasing trend of Cat2 and Cat3 (Cat1 has a dip too). A is wrong (no data for "cease"). C: Cat2 is decreasing, not rising. D: Cat1 is not stable.

Answer:

A 15 °C
