"Would he press the red button?"

Translation: Würde er den roten Knopf drücken?

[rauchbier123]

seems like there should be an "auf" in there..."auf den Knopf". Nicht wahr?

[Michael65088]

That would be "press ON the button", which basically means the same thing and I reckon it should be accepted if it isn't already, but it's not necessary in either language
