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_ZqxC):
Solve for a: 12*a + 17 = 89 Respond with an integer.

Question 1 (Question id: q_7wHc0):
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: "biology"

Question 2 (Question id: q_3cdMs):
How many times does the letter "t" appear in the text: "to the United"? Respond with an integer.



Produce a JSON object whose top-level keys are the question ids.

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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_ZqxC": {"answer": 6, "half_answer": 3}, "q_7wHc0": {"answer": "y"}, "q_3cdMs": {"answer": 3, "task_type": "letter_counting"}}}
