Friendly is the correct answer<span />
The proper way to write the sentence would be "However, no one believed rumors about the Komodo dragon either." Since commas are used after words like "first, second, third, then, finally, however, but..." there would only be 1 comma in this sentence.
I hope this helps!!
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.
