Pitanja na engleskom - IS, ARE ili DO ?

Mona Lisa, Mona Lisa
Men have named you
You're so like the lady with the mystic smile
_______ it only cause you're lonely
They have blamed you
For that Mona Lisa strangeness in your smile?

***
_________you smile to tempt a lover, Mona Lisa ?
Or
________ this your way to hide a broken heart ?
Many dreams have been brought to your doorstep.
They just lie there, and they die there.
________ you warm, are you real, Mona Lisa
Or
just a cold and lonely, lovely work of art ?
