"Short, long, who knows?"

Translation: Curto, longo, quem sabe?

[rolosrevenge]

Is there are reason why using the feminine versions of these words is wrong?

[giovannaiglesias]

When we are generalizing things on Portuguese, we use the masculine words.

[PHScanes]

Where's the generalization in it?

[Danielconcasco]

There is no noun. We're generalizing. Most Romance languages default to masculine. It's a remnant of Roman sexism.

[SimonKoch-Sultan]

Hebrew also defaults to masculine. And historically, English has too, although singular they has been fairly universally adopted in colloquial speech.

Is using "comprido" instead of longo incorrect?

[amckel]

quem é que sabe? Não pode ser?

[PHScanes]

Pode... it's possible

[Delcriram]

Shouldn't sei lá be accepted for who knows here?

[DaveGarrar]

I have exactly what you have but it is marked wrong. Why?
