Answer:
AABB
Explanation:
The rhyme scheme is defined as the sequential pattern that the poet adopts for the end words of each line in order to offer a rhyming effect to the poem and make it more memorable. In the poem titled 'Drop a Pebble in the Water' by James William Foley, the rhyme scheme of 'AABB' is followed throughout the poem as the end words of the first two lines(gone, on) and the last words of the third and fourth line('sea' and 'be') rhyme with each other.
