잠그다 lock, turn off, fasten, zip up

[Vadim282631]

why not 가스를?

[CosmoDC]

It is also correct without the 제발. I am guessing using 제발 shows some kind of desperation or exasperation?

[Wang_Jackson]

Lock the gas?

[Sarah610755]

Maybe Duo doesn't like 좀 which implies 'a bit'. Turning the gas off a bit is not turning the gas off!

제발 가스는 잠그세요
is also correct

Papago suggests this transition: 가스 좀 꺼주세요. But Duolingo marks it wrong. True?
