Explanation: The lowest temperature observed was -8°C at 5:00 AM, corresponding to the second thermometer. The highest temperature observed was 12°C at 5:00 PM, corresponding to the fourth thermometer. The 11:00 AM reading of 3°C corresponds to the third thermometer. The first thermometer showing -2°C is not explicitly assigned a time but would fit as an intermediate reading.
