“The school is offering art classes to all of its students” is the correct answer
C. How long does it take to travel from the Earth to the moon?
This is the weakest research question because it can be easily answered. According to a 2 second Google search, it takes about 3 days for a spacecraft to reach the moon from Earth. This question does not allow for a lot of research for development into an essay. Options A, B and D all have a variety of possibilities that would allow for a multi-paragraph essay with significant topic development.
The answer: C
“As a matter of fact, my dog does know the difference between a treat and a vitamin.”
I hope this helps :)
