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_5ZUYlEQ):
Find the value of d in the equation: 18*d + 11 = 263 Respond with an integer.

Question 1 (Question id: q_wA3lxwP):
How many times does the letter "b" appear in the text: "distribute this"? Respond with an integer.

Question 2 (Question id: q_21Vd0S9y):
Determine the value of d that satisfies: 18*d = 306 Respond with an integer.



Create a JSON object keyed by every question id except q_21Vd0S9y.

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

Now provide the result JSON using the described format.

{"ground_truth": {"q_wA3lxwP": {"answer": 1}, "q_5ZUYlEQ": {"answer": 14, "half_answer": 7}}}
