See those two girls? Helen is the tall one and Jane is the short one.
Which is your car, the red one or the blue one?
My trousers are torn. I need some new ones.

See those two girls? Helen is the one on the left.
Let's look at the photographs – the ones you took in Paris.

hii!! thanks 4 ur working it is really verry interesting & nice

iam little bit confused about using article one of those
may i ask what's is the rght one between one of those factories are soybean factory or one of those factories is soybean factory?
thanks

Hello yun samaniah,
The clue is in the phrase: 'one of those...' tells us that you are talking about one thing, not many, so the verb should be singular:
'One of those factories is a soybean factory.'
You need an indefinite article as well because it is the first time it has been mentioned.  If you had talked about the soybean factory before then you might say 'the'.  For example:
'I work in a soybean factory.  One of those factories is the soybean factory.'
I hope that clears it up for you.
Best wishes,
