After considering these questions, I concluded they have practically nothing to do with logical reasoning. As matter of fact, only Q4 and Q5 make some sense to me. For example, from 4 shapes in Q1 one can make a rectangle (answer "A"). But who asks you to make a rectangle? The answer may be "D" too, because it is small and pointy just as 4 previous shapes. In Q2, I would pick answer "A", simply on the basis of the next door similarity. And Q3 is a complete randomizer. Any answer can be correct
