ANSWER:

The values are converted based on the ASCII alphabet, in which uppercase letters come before lowercase letters, and thus are assigned a lower value than the lowercase letters. This means that the word ‘apple’ is assigned a higher value than the word ‘ORANGE’ because of the case-sensitivity, making ‘apple’ greater than ‘ORANGE.’ When we change ‘ORANGE’ to lowercase, the otherwise same code would return ‘orange.’
