"조종사가 술을 많이 마셔서 실직했어요."

Translation: The pilot drank a lot of alcohol and lost his job.

Lost her job must also be accepted!!

[Komerinam]

It should be: The pilot lost his/her job "because" he/she drank a lot of alcohol. since it's "마셔서" (=because ...[someone] drank).

[neofotistou]

Lost her job for drinking too much might also be an apt translation. You rock, duolingo people

Reminds me of the movie "Flight" from 2012 with Denzel Washington. It's worth a watch.

[KJ41510]

I thought the same. Can't go wrong with a Denzel movie!

서 is a "cause & effect" conjunction, best translated as "and so".

[Clause1]서 [Clause2] ->
[Clause1] and so [Clause2]

"and" by itself is a coordination conjunction; hence not an accurate translation of 서.
