The sentence you see in the title is from my English lesson. Thought I was OK with the Present Perfect, but I'm not so confident now.
The explanation says that I can translate this sentence as "they have lived in Paris for 5 years and they still live there (because of NOW)"
As I know, Present Perfect is about something that has started in the past and/or just finished and/or still has the connection with the present.
Probably the connection with the present is about my example, but using the word NOW with the PP and "for...years" seems strange to me.
Is it OK?
