What poetic form do both montagu's and swift's poems use?

Lady Mary Wortley Montagu used iambic tetrameter rhyming couplets is some poems such as "The Lover: A Ballad" and in others free mingling of iambs, also with rhyming couplets, on the other hand, Jonathan Swift uses rhyming pairs of lines, both used rhyming couplets.

the answer is both an appeal to ethos and logos (if that's what your question options were)
