Which of the following is nota quality of free verse?

a rhythmic pattern

no regular meter

end-stopped lines

rhyming lines

I'd say the answer is the first one, 'a rhythmic pattern'. Because a free verse fights schematics, rules, etc. And if there is a pattern, then that is some kind of a scheme, or rule, which the poets do not allow in their free verse poems. It should be free of any patterns.
