Question 1 of 3

1. Question

Your extraction prompt asks for JSON but doesn’t specify what to do when a field has no value. What’s the likely consequence?

Nothing, Claude always handles this consistently on its own
Correct Incorrect Correct answer

Inconsistent output across runs — sometimes null, sometimes an empty string, sometimes the field omitted entirely — since the edge case was never defined
Correct Incorrect Correct answer

The prompt will fail to run
Correct Incorrect Correct answer

JSON always defaults to empty string automatically
Correct Incorrect Correct answer

Question 2 of 3

2. Question

You’re piping Claude’s JSON output directly into a script that calls JSON.parse() on it, and the script keeps crashing. What’s the most likely cause?

Claude cannot produce valid JSON under any circumstances
Correct Incorrect Correct answer

Claude is adding a conversational preamble or wrapping the JSON in a markdown code fence that you didn't explicitly rule out
Correct Incorrect Correct answer

The script has a syntax error unrelated to Claude
Correct Incorrect Correct answer

JSON.parse() is broken
Correct Incorrect Correct answer

Question 3 of 3

3. Question

For output meant to be read by a human reviewer rather than parsed by strict code, what’s an advantage of XML-style tags over strict JSON?

XML tags are always shorter
Correct Incorrect Correct answer

Tags degrade more gracefully if Claude adds a stray sentence, since a parser looking for content between two known tags is more forgiving than one expecting valid JSON syntax
Correct Incorrect Correct answer

JSON cannot be read by humans at all
Correct Incorrect Correct answer

There is no advantage, they are identical
Correct Incorrect Correct answer

Correct

Incorrect
