The answer doesn't make any sense whatsoever. Nor are the hints any help. In looking up 'supporre' I found 'to imagine' and I used that and -- imagine this! -- it was accepted! Why couldn't 'to imagine' have been given as one of the hints. I presume DL told them not to. John & Yoko would be disappointed.
I am not saying I think this is a good sentence but I have a possible context. In physics/math class we were often told to assume things. We were given a problem and then we would start with (for example): Assume that the container is 100 cubic meters. And with that assumption we we could work out the problem.
I'm so happy when i get ready to follow the discussion, but figure out my question before I get here. :)
I couldn't understand why it wasn't "hai detti" since "ci" is a plural pronoun and what I first thought was a direct object pronoun, when it is actually an indirect object pronoun, so the rule doesn't apply.
I love and appreciate this community of fellow lovers of the art of language. :)
