Their instructions are unclear, imo. They say “Copy and paste your answer from the Atlas UI to the response text box. The station name should be in a single set double quotes, exactly as it is in the Data Explorer.”
When you copy paste the answer, this comes out:
end station name
"South End Ave & Liberty St"
It’s confusing because you do not actually copy paste the answer + make sure the station name is in double quotes. The phrase “exactly like it is in the Data Explorer” furthermore gives the impression that your answer should look exactly like it does in the Data Explorer, which is:
end station name: "South End Ave & Liberty St"
But you have to give the answer in the correct JSON format altogether. If they add “make sure your answer is in the correct JSON format”, it would be clearer.
