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_HdDFsRzy):
Calculate 9 - 9.

Question 1 (Question id: q_WxkIva):
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: "the"

Question 2 (Question id: q_tsBOmfA6):
Solve for z: -14*z - 3 = -213 Respond with an integer.



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 integer answers, include 'half_answer' equal to answer ÷ 2.
For last-character tasks, provide 'original_string' alongside the answer.

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_HdDFsRzy": {"answer": 0, "answer_type": "integer", "half_answer": 0}, "q_WxkIva": {"answer": "e", "answer_type": "string", "original_string": "the"}, "q_tsBOmfA6": {"answer": 15, "answer_type": "integer"}, "global_metadata": {"num_questions_asked": 3}}}
