Triglycerides are fats. Saturated fats are solid at room temperature while unsaturated fats are liquid at room temperature. This is because these two kinds of fats differ in their chemical structure.
Saturated fats do not have double bonds between the molecules which means there are no gaps and the fat is saturated with hydrogen molecules. Because there are no gaps, these fats tend to pack more closely together.
Unsaturated fats have double bonds which break up the chain of hydrogen molecules and create gaps allowing them to pack loosely and can thus liquefy at room temperature.
Unexpected means it was something you did not "expect" to happen such as a car crashing into you which means this is wrong.
Unfair is any injury.
Unnecessary means it was never needed and could have been prevented/not done therefore unnecessary is the best term.

Explanation:
I'm assuming that you're talking about all of this in the US so that's what I'm basing my answers around when it's applicable but it's difficult because a lot of these seem to be just opinion and answers could be changed based off of personal belief considering that the majority of the questions are not strictly fact based like #2 is, but I hope that this helps :)
