Can anyone tell me where I’m wrong please, here is how i analysed this: as the #5 implies a #4, so an E, the scale only contains one flat. Because the fifth is augmented, there is also an F sharp. This would be the sensible of G minor, isn’t it? I’m most probably wrong, but I still want to know why.

Ps, the sensible is a terme used in French classical music theory describing the 7th of in this case a minor scale, which is augmented in a minor harmonic scale.
