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_ZjYYjy9Q):
Calculate 7 / 7 + -1.

Question 1 (Question id: q_eHD3gF):
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 wasps, 4 cats, 4 cows?
 Respond with an integer.

Question 2 (Question id: q_uUje):
Determine the value of a that satisfies: 26*a = 494 Respond with an integer.



Create a JSON object keyed by every question id except q_ZjYYjy9Q.

The value for each key should be an object that contains the answer in the field 'answer'.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
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.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
'num_questions_answered' must hold the number of answered questions.

Now provide the result JSON using the described format.

{"ground_truth": {"q_eHD3gF": {"answer": 50, "half_answer": 25}, "q_uUje": {"answer": 19}, "global_metadata": {"num_questions_asked": 3, "num_questions_answered": 2}}}
