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_sezwtVNI):
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 1 snake, 4 flatworms, 3 lions, 1 praying mantis, 1 human?
 Respond with an integer.

Question 1 (Question id: q_GPQivQc):
Calculate ( ( -3 - -4 * 2 ) ).



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

The value for each key should be an object that contains the answer in the field 'answer'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_sezwtVNI": {"answer": 20, "answer_type": "integer", "additional_answer_info": {"half_answer": 10, "double_answer": 40}}}}
