Final answer:
The greater value in text comparison is determined by its position in the alphabet.
Step-by-step explanation:
When comparing text using the operators >, >=, <, and <=, the greater value is the one that appears later in the alphabet. In other words, the letters are compared based on their position in the alphabetical order.
For example, 'banana' < 'cherry' because 'cherry' appears later in the alphabet than 'banana'.
Similarly, 'apple' <= 'apple' because both 'apple' are the same text and they are considered equal.
