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_Dj4CHgKG):
Solve for k: 12*k - 9 = 219 Respond with an integer.

Question 1 (Question id: q_pHfJwjhh):
Your job is to return the last character of a string as a string. For example, the last char of "hello" is "o". Return the last character of the following string: "why"



Return a JSON with each question id as a key.

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.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked: how many questions were asked in total.

Now provide the result JSON using the described format.

{"ground_truth": {"q_Dj4CHgKG": {"answer": 19, "answer_type": "integer"}, "q_pHfJwjhh": {"answer": "y", "answer_type": "string", "original_string": "why"}, "global_metadata": {"num_questions_asked": 2}}}
