Identify the stamp used for printing the sample (in blue) from the options given below. 
Key fact. A stamp prints a mirror image of itself (left–right reversal). Any further rotation of the stamp does not change this mirror relation; the print just appears rotated accordingly.
Apply to the sample.
The printed word shows the letters B E in their normal reading order, with the small star above (near the top edge). Therefore the stamp that produced it must have the letters arranged so that, when mirrored, they appear as a normal “BE”.
Among the choices, only (B) has the letters oriented such that a mirror-print yields the normal “BE” with the star above. Options (A) and (C) have a mirrored “ƎB” layout, whose print would read “\(\text{E}B\)” reversed, and (D) would also print incorrectly with the star position inconsistent. Hence the stamp is \(\boxed{(B)}\).
One square and 4 triangles given below are used to make shapes without overlapping. Among the options, which is the shape that CANNOT be made? 
Given is the one side of a folded sheet of paper with green color on one side and red color on the other side. Find the correct option when this sheet is unfolded. Dotted lines represent the fold lines. 
Which option(s) is/are NOT a part of the image on the left? 
Sal tree seed moves in a particular manner while free falling. Which toy(s) given below has/have a similar movement? 
The pixels in the image on the left are shifted horizontally to create one or more options on the right side. Identify the correct option(s).
