In questions having 'one of the Xs that (verb)' the verb agrees with X .. and is plural
What about questions like these where 'patchwork of fields that surround(s)' .... should it be surround or surrounds and why ?
It is clear that "bustles" should match with patchwork and hence singular ... but am not clear on surround(s)
