A 6-hour maximum temperature of 14.5°C and a 6-hour minimum temperature of -1.5°C should be recorded in column 14 as:

To determine the appropriate format for recording the maximum and minimum temperatures in column 14, it is important to understand how to encode temperature data.

In this context, the maximum temperature of 14.5°C is recorded as 10145. This code is broken down as follows: the first digit (1) indicates that it is a maximum temperature, and the next four digits represent the temperature in tenths of degrees Celsius. Therefore, 14.5°C converts to 145 in tenths (14.5 x 10), which gives us 10145.

The minimum temperature of -1.5°C is recorded as 21015. The initial digit (2) shows that this is a minimum temperature, and the following digits again represent the temperature in tenths of degrees Celsius. Since -1.5°C translates to -15 in tenths (as temperatures below freezing are denoted differently), it leads to the corresponding value of 21015.

In summary, the maximum temperature of 14.5°C is recorded as 10145 and the minimum temperature of -1.5°C as 21015, making the correct recording for column 14 10145 21015. The provided answer accurately reflects this method of encoding
