"בתל אביב יש רכבת תחתית."
Translation:In Tel Aviv there is a metro.
... yet! The team just wanted to make sure the course is future proof. :)
There is a light rail system under construction in Tel Aviv, part of which will be underground. But, it's still years from being finished.
עדיין לא. בתל אביב יש רכבת קלה. There WILL be רכבת תחתית but we haven't learned future tense yet so I guess we get to talk about it in present tense.
Subway should be accepted; in fact, it's one of the translations offered on the mouseover. I reported it.
Tube is fine, subway or metro would work, but there needs to be an 'a', in tel Aviv there is A tube
"In Tel Aviv there is subway". Really comrade? Try " In Tel Aviv there is a subway "
