Question

The poetic form of “your laughter” is known as _____. blank verse free verse pentameter sonnet

Answer 1

The poetic form of “your laughter” is known as free verse, because it doesn't follow any rules regarding rhyme schemes or the overall structure of the poem. 
Blank verse is written in pentameter, so that answer, as well as pentameter are incorrect. It isn't a sonnet either, because sonnets have only 14 lines.
