Some time back, I also incidentally explored this issue. Looks quite tricky. I came across a similar sentence, but thankfully the question does not ask us to pick between singular/plural (verb is not in the underlined portion)
According to a recent poll, owning and living in a freestanding house on its own land
is still a goal of a majority of young adults,
as it was of earlier generations.
If this comes in the underlined portion, then this will be a killer;).
