"Hvilken undergrundsbane tager vi med?"

Translation: Which subway are we going with?

[bronshojbob]

Why wouldn't "Which subway are we taking?" work?

[joelmagoun]

This is what I put, and it was accepted.

[Jack402144]

A native English speaker would always say which subway are we taking

[NGN410833]

"going with" is improbable - "taking" is more likely

[DavidJrgen2]

Subway means something else in British English, I think 'Which tube/Tube are we taking?' is also acceptable.

[potatoemouse]

I would say underground should be accepted too.

Why do you meed "med"? Could you just omit?

[christoikos]

"Which metro are we going with" isn't correct?

[Patsy536249]

A few lessons back it had gar so I used taking this time. Not accepted

Microphone still sucks...
