To solve this problem, we need to determine if the integer returned by the given function get_answer() is even. An even number is defined as any integer that is divisible by 2 with no remainder.

Approach

The approach to solve this problem involves two main steps:

1. Retrieve the Answer: Call the get_answer() function to get the integer result.
2. Check Evenness: Determine if the retrieved integer is even by checking if it leaves a remainder of 0 when divided by 2. This can be done using the modulus operator (%), where num % 2 == 0 will be True if num is even, and False otherwise.

Solution Code

def is_answer_even():
    return get_answer() % 2 == 0

Explanation

• Retrieve the Answer: The function get_answer() is called directly to get the integer value we need to check.
• Check Evenness: Using the modulus operator (%), we compute the remainder when the result from get_answer() is divided by 2. If the remainder is 0, the number is even, so the expression get_answer() % 2 == 0 returns True. Otherwise, it returns False.

This approach efficiently checks the evenness of the result with a single line of code, ensuring correctness for all integers (positive, negative, or zero). For example:

• If get_answer() returns 6, 6 % 2 ==0 → True.
• If get_answer() returns -3, -3%2 ==1 → False.
• If get_answer() returns 0, 0%2 ==0 → True (since zero is even).

Answer:
The function is_answer_even() as written above is the correct solution.
