Mr. Bedford, you should definitely go to the moon. It is a once in a lifetime opportunity and you could not just turn it down. I know that there are risks of failure that could end badly, but it is worth it. You have worked so hard with Mr. Cavor that you can't just give this up. Yes your business had a downfall but that shoukd not stop you. I know that you might be a little scared or unsure if this will work and I can see that. What is you say no, but it works. What if it works and everything goes right, but you missed the opportunity to go to space, to see that stars and the moon, to see our planet in a way no one has ever seen it before. Then would you be sad and angry that you said no. Then would you have wanted to go and wished you said yes. Keep up the good work and you will make it, you will succeed and it will all be worth it.
it's C cause in the meaning of premise, it says a statement assumed to be true. that sentence about pretzel is assuming that pretzels are better than chips
I feel as if B helps explain the conflict more. Whereas the other answers are just details or add ons in the short story. Also the other answers seem more external than B.
All the other options seem like good reasons but are not as important as improving your overall skills (from my perspective at least). Hope this helps!
