The free body diagram consists of:
1) Weight force, which is a vertical arrow downward
2) A Normal force that is perpendicular to the ramp.
The Normal force can be decomposed in a vertical component and an horizontal component.
The vertical component, Ny, must equal the weight force, due to equilibrium (rest) condiition =>
Ny = weight = m*g = 5.5kg*9.8m/s^2 = 53.9 N
By geometry the vertical component of the Normal force, Ny is such that
cos (angle) = N / Ny => N = Ny * cos(angle)
=> N = 53.9N * cos(angle)
Now use that equation for each option:
a) 0 ° => N = 53.9N * cos(0) = 53.9N
b) 12° => N = 53.9 * cos(12) = 52.7N
c) 25° => N = 53.9 * cos(25) = 48.9N
d) 45° => N = 53.9 * cos(45) = 38.1N

Answer:
since 1970 many people have switched to almond or other cow milk substitutes. Others just simply dont drink milk. Organic farms have been showing up in recent history due to the growth of health awareness and the benefits of farm fresh organic foods. Organic fresh food also tastes a lot better than frozen superstore bought foods.

those are just some plot points sorry if they aren't full explanations this was meant to just give you a central idea and move forward with it and create your own ideas and flow using some basic points. if you would like more I'd be glad to go into more detail :)
