Either the ancient Etruscans were experienced city planners and they invented the art of writing or they were highly skilled engineers and they invented the art of writing. If the ancient Etruscans were bloodthirsty numskulls (as scholars once thought), they did not invent the art of writing. Therefore, the ancient Etruscans were not bloodthirsty numskulls (as scholars once thought). (C = The ancient Etruscans were experienced city planners. I = The ancient Etruscans invented the art of writing. H = The ancient Etruscans were highly skilled engineers. B = The ancient Etruscans were bloodthirsty numskulls.)
it said i need to put all the premise in first following this order For example, if premises are A and A⊃B, and the conclusion is B then enter A/A⊃B//B.
