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_Gq9QIXT):
Solve for w: 162*w + 1134 = 2916 Respond with an integer.

Question 1 (Question id: q_r2jPR):
How many times does the letter "n" appear in the text: "and gone"? Respond with an integer.

Question 2 (Question id: q_l0gR00W):
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: "environment"



Create a JSON object keyed by every question id except q_l0gR00W.

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_r2jPR": {"answer": 2, "half_answer": 1}, "q_Gq9QIXT": {"answer": 11}}}
