We do not know that the professor told, there can be an order of figures matters. For some reason it did not outline it.

For some reason it did not outline it your variant wrong because it is possible to offer an alternative variant. Besides it is boring. I, for example, thought that a superfluous that figure which is not visible - too small or too black. Too black - , we know that  can not be. , we know that color can be red or green. Well so why not black without ? Too small - , we know that the size varies. So why not to assume, what the superfluous figure has the size a zero ? Let's recognize that all the same the decision unambiguous and unique. The correct decision always one. These are errors at all different." Correct "the decision too starts with certain restrictions. About same. I.e. there are black figures or figures of the zero size. Or that the color-blind person drew. Otherwise the"correct"criteria of an estimation would not give any result. In this sense these two decisions are equivalent. Into the account , it you to mine to 17 son tell, which offered the"correct"variant in flow of 20 seconds (Unified State Examination on the mathematician - 72, to the physicist - 56).

Hello, nikov, you wrote: N> the First - unlike remaining figures, has no unique distinguisher... Oh, or it also is its distinguisher? A distinguisher - absence of a distinguisher? Well, in such , the first figure has no distinguisher which can be described without oxymorons

If to recognize that the task has the unambiguous decision it is all simplifies. The unambiguous decision can be only in a statement "What of the figures represented on a board superfluous?". And that, it is possible to carp at a word "superfluous". Any (except the first) a figure can be superfluous for the task of determination of a superfluous figure of that on a board. We remove a green figure and the task remains with the same decision. Uniqueness does not suffice, since any (except the first) can be superfluous, and without the first not to find the superfluous. And here the statement "Find" implies search process at the decision. Not a choice, namely search. And hardly search among that near by.

By criterion the frame falls out the second figure (has no frame) By criterion the form the third falls out (a circle instead of a square) By criterion color falls out quarter (a green square) By criterion the size falls out the fifth (a small square) by any criterion the first does not fall out. Hence it superfluous.

(Geometrical) Figures I see two - a circle and a rectangle. Accordingly the answer can be only two. Either a circle or a square. What of them superfluous depends on that what exactly such "superfluous". With  the points of view (true - not superfluous, false - superfluous) in the single copy only the circle, means it true.  a little - one of rectangles not the true means. I.e. a superfluous figure - a rectangle. Well and at home level - a circle in the single copy. From this point of view a superfluous figure - a circle.
