The problem presents a short Python code snippet and asks what gets displayed when it runs. 
First, consider the list x = [5, 3, 7, 9, 1]. The elements are indexed from 0:
- index 0 -> 5
- index 1 -> 3
- index 2 -> 7
- index 3 -> 9
- index 4 -> 1
Next, the slice y = x[2:4] is taken. In Python, list slicing x[a:b] yields a new list of elements starting at index a and up to, but not including, index b. This means it includes elements with indices 2 and 3, but excludes index 4. 
Therefore, y contains the elements at indices 2 and 3, which are 7 and 9. 
When print(y) is executed, Python outputs the list [7, 9]. 
Note: The provided data shows an empty set of answer options, which means there are no alternative choices to evaluate for correctness in this instance. If options were present, we would compare each option against the actual slice result [7, 9] and justify why it matches or conflicts with the slice behavior. In this context, the key concept being tested is Python’s list slicing semantics, specifically that the end index is exclusive.
