Here is a set of basic questions producing integer or string outputs. Answer them and format the result precisely with the JSON instructions provided:

Question 0 (Question id: q_9H9GGRL):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 3 humans, 2 insects, 2 grasshoppers, 1 flatworm?
 Respond with an integer.

Question 1 (Question id: q_vwsxYmM):
Calculate 8 * 2.



Output JSON where all question ids are keys, omitting q_vwsxYmM.

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.

{"ground_truth": {"q_9H9GGRL": {"answer": 30, "half_answer": 15}}}
