Parallel lines s and t are cut by a transversal r. which angles are alternate exterior angles? 2 and 8 4 and 6 1 and 5 1 and 8

"Alternate" means the angles are on opposite sides of the transversal.

Any of angles 1, 4, 5, and 8 are alternate with any of angles 2, 3, 6, and 7.

1 and 5, 1 and 8 are "same side" angles (not alternate), so those answer choices can be excluded from consideration.

___

"Exterior" means that the angles are outside (not between) the parallel lines. Angles 1, 2, 7, 8 are exterior angles. Angles 3, 4, 5, 6 are interior angles (between the parallel lines). Thus answer choice "4 and 6" can be excluded from consiideration.

The appropriate (and only remaining) choice for "alternate exterior angles" is ...

... 2 and 8

Angles 1 and 7 are also alternate exterior angles, but that selection is not on your list of answer choices.
