After making the Digerati IQ check (http://play.google.com/retailer/apps/particulars?id=cz.digerati.iqtest) there are three questions the place I nonetheless do not understand how they arrive to the proper (inexperienced) reply. Can any person clarify?

My reasoning: a giant circle can not have an open aspect, however other than that, the left column has the open aspect on the underside, the middle column has the open aspect on the left and the proper column has the open aspect on the proper. So my reply (B) makes completely sense to me, however apparently it is mistaken. How is (E) extra logical?

No clue

I’ve some rationalization to come back to (B), however apparently it is mistaken.

(If it ought to be three completely different questions let me know. I simply did not wish to spam the board.)
