The image contains three thermometers showing different temperatures. The question asks to fill in a table with temperature observations for 6:00, 10:00, and 14:00, given that 6:00 was the lowest temperature and 14:00 was the highest. Based on the thermometers: The first thermometer shows a temperature of -10°C. The second thermometer shows a temperature of 10°C. The third thermometer shows a temperature of 30°C. Assuming the thermometers represent the temperatures at different times of the day, and given that 6:00 had the lowest temperature and 14:00 had the highest, we can assign the temperatures accordingly. The 10:00 temperature should be between the lowest and highest. Therefore, we can infer the temperatures as follows: 6:00 (lowest) = -10°C, 10:00 (middle) = 10°C, 14:00 (highest) = 30°C.
