The cloud is really big and really dark?
Two times really?. Why???
I wrote 'quite' instead of 'really'. It was not accepted.

I feel very confused about tosi. I thought it was also very, but "...very large and very dark" was marked incorrect.
Very is better translated as hyvin.
Very large and very dark - Hyvin suuri ja hyvin tumma
