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_Z2SbVkRB):
Determine the value of d that satisfies: 11*d + 13 = 79 Respond with an integer.

Question 1 (Question id: q_PNj9L):
How many times does the letter "h" appear in the text: "their air"? Respond with an integer.

Question 2 (Question id: q_I4Wnt5D):
Find the value of c in the equation: 14*c + 10 = 262 Respond with an integer.



Return a JSON with each question id (except for q_Z2SbVkRB) as a key.

Each key’s value must be an object holding an 'answer' field. Additionally, if the task is about counting legs of animals or counting letters in a string, add the task_type field with value 'leg_counting' or 'letter_counting', respectively.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
For string answers, include 'first_char' with the answer’s initial letter.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.

{"ground_truth": {"q_PNj9L": {"answer": 1, "task_type": "letter_counting"}, "q_I4Wnt5D": {"answer": 18, "half_answer": 9}}}
