None of the options is less than both temperatures the meteorologist recorded
Since the first day the temperature was −3.1° Celsius. The second day the temperature was 1.2° Celsius.
For a temperature to be less than both temperatures, it has to be less than the lowest temperature which is −3.1° Celsius. Since −3.1° Celsius is less than 1.2° Celsius.
Now comparing both numbers with the the given options.
We see that 5.1° Celsisus is greater than -3.1° Celsius.
So, this option is wrong
Option 2 : 5.5 degrees Celsius
We see that 5.5° Celsisus is greater than -3.1° Celsius.
So, this option is wrong
Option 3 : 0 °Celsius
We see that 0° Celsisus is greater than -3.1° Celsius.
So, this option is wrong
Option 4 : -2.9° Celsius
We see that -2.9° Celsisus is greater than -3.1° Celsius.
So, this option is wrong
So, none of the options is less than both temperatures the meteorologist recorded
