Hello!
Thank you trying it out, very sorry to hear you had a bad experience.
Well,
1) that section is a bit fickle, i'd double check for extra spaces/new lines.
2) That section is also incorrect, the correct way to print and array in quotes is ..
print("\"" , b , "\"")
3. thank you pointing this out!
4. If all else fails [for now] You can find the answers to each section in the Progress Map tab
Also, sometimes there's an extra space after entering your answer, I'd double check for that also. Hoping to fix this little issue at some point.
Peace, RR
