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_vvt4tlw1):
How many times does the letter "s" appear in the text: "Mr Smith"? Respond with an integer.

Question 1 (Question id: q_r8NHxH):
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 2 scorpions, 1 bird, 2 lions, 4 snakes?
 Respond with an integer.

Question 2 (Question id: q_ekiAbs):
Calculate ( -4 + -1 * -5 ).



Produce a JSON object whose top-level keys are the question ids.

For every question id, supply an object whose 'answer' field stores the solution.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Set 'num_questions_asked' to the count of questions originally displayed.

Now provide the result JSON using the described format.

{"ground_truth": {"q_vvt4tlw1": {"answer": 1}, "q_r8NHxH": {"answer": 26, "additional_answer_info": {"half_answer": 13, "double_answer": 52}}, "q_ekiAbs": {"answer": 1}, "global_metadata": {"num_questions_asked": 3}}}
