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_stzB):
Determine the value of w that satisfies: 18*w + 12 = 66 Respond with an integer.

Question 1 (Question id: q_6DEa):
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: "believe"



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.

Now provide the result JSON using the described format.

{"ground_truth": {"q_stzB": {"answer": 3, "answer_type": "integer"}, "q_6DEa": {"answer": "e", "answer_type": "string"}}}
