# JCTI Test: Find the next box

This is a JCTI question ,where I need to fill up the blank spot by any of the 6 given boxes.

I cannot understand from where these two balls within a single box is coming. All the previous boxes contained just one ball! Moreover the first two (up and down in a single column) are squares, the second two are rhombuses, the third two are again squares, so the last two (the rightmost one and the one to be filled up) should be rhombuses. But given is a square!! Please solve this puzzle.
