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 \(\boxed{(B)}\).

An intersection is a point where two or more lines/curves meet or cross. How many intersections are there in the figure given below? 

The drawing shows the figure of a horse with the point (marked with a red dot) where the pelvic girdle meets the vertebral column. Which of the options shows simplified bone linkages for the hind leg of the horse beginning with the red dot?
