We’re given the list a = [3, 2, 1, 'hello', [10, -10], 5, 6] and asked which slice will produce ['hello', [10, -10]] from it.

Option 1: a[-4:-2]
- Understanding indexes from the end: -1 is 6, -2 is 5, -3 is [10, -10], -4 is 'hello'.
- The slice -4:-2 starts at index -4 ('hello') and goes up to but does not include index -2 (which is 5).
- Therefore it collects elements at positions 'hello' and [10, -10], yielding ['hello', [10, -10]].

Option 2: a[-4:-3]
- This slice starts at -4 ('hello') and goes up to but does not include -3 ([10, -10]).
- It includes only 'hello'.

Option 3: a[4:6]
- This uses positive indices: index 4 is [10, -10], index 5 is 5, and stops before index 6.
- Result would be [[10, -10], 5], which is not the target.

Option 4: a[-3:-1]
- Here -3 is [10, -10] and -1 is 6, stopping before -1.
- This yields [[10, -10], 5], which again is not the target.

In sum, comparing all options to the requested output, only the slice a[-4:-2] produces ['hello', [10, -10]].
