"...country is a nation’s newspapers" how to use is & are properl

[Faithsmimi]

I am having problems with the correct use of the subject-verb agreement. Here
is an example of one of my assignments:

"One of the world's oldest and most famous newspaper centers (are/is) Fleet
Street. This area, with its hundreds of alleys, (run/ran) like a crooked
spine through east-central London. Here (are/is) published almost all of
Britain's national newspapers. In no other country (are/is) a nation's
newspapers centered in once location."

English has never been one of my strong points. Can someone please help me
with an easy way to remember the rule? Please help!! Thank you so much.

The subject of "One of..." is one, obviously singular, so the verb will be
"is." Second sentence: subject is area, also singular, verb "runs" (not one
of your choices???). Third sentence: while the elements are reversed,
"newspapers" is the subject; plural, so verb should be "are published." Same
with the last sentence--"are centered."
