I think it would be more logical to use the past tense i.e. those books were written by this woman. The action of writing has past but the meeting or introduction of the person is happening now.

I don't understand the difference between "Those" and "These" .... Sometimes "đó" is accepted, sometimes it isn't.
"were written" should be accepted per the drop down explanation but I know it is a big waste of time to even mention anything here.
