yeah thats what I got too. but the picture is skewed a bit.
in the original picture, its very hard to differentiate 1 with 4, but its easy that the 2 is largest, and slightly larger than 3 > 1or4
the solution has them (this plus 2 more that i suspected in a test) marked wrong too, so i thought i was going crazy. but all's good *back to study*
