Three Spatial Reasoning Problems

This month has three seperate spatial reasoning type questions.
You must give a simple reason / explanation of your thought process
that supports your answer for each Problem.

Problem #1
Which two (and only two) different fragments, when stacked together, create the "Sun" shown in the center?  You may rotate each fragment as you like, but you may NOT FLIP them over. (No overlapping of the lines.. so pick carefully)

Problem #2
Using the attached diagram, show how the six pieces can form the full grid.  You CAN rotate pieces, flip them over and cross them in their narrow places.  But do NOT bend or overlap pieces.
You will likely cut and paste to give your solution, but other drawing methods are acceptable too.
(The order and position of the black and white tips do NOT matter.)
