[EX Q]: Question: Would a star that is significantly cooler than the sun, which is outputting blue light which is higher in frequency that the yellow light of the Sun, be 
 Answer: colder?
[EX A]: Shorter wavelengths (higher frequencies) correspond to higher energies and thus hotter star temperatures.

[EX Q]: Question: If Mona is building a machine to help her vacuum her floor and she decreases the amount of force the engine inside the vacuum, what happens to the vacuum ability to make work easier? 
 Answer: decreases
[EX A]:
Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied.
