Mi adresis la leteron al mia onklino.

I addressed the letter to my aunt.

Tamen, Nun ni adresu nin al unu el la ŝipanoj, respondeca pri biologia parto de la ekspedicio.

Though it's no problem, we'll speak to one of the crew members who is in charge of the biological side of the expedition.

Al kiu mi adresu la leteron?

Who should I address the letter to?
