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_hq2mu):
How many times does the letter "t" appear in the text: "donation methods"? Respond with an integer.

Question 1 (Question id: q_HUbDH):
Calculate 8 + -3.



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

The value for each key should be an object that contains the answer in the field 'answer'. 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.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
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_hq2mu": {"answer": 2, "task_type": "letter_counting", "half_answer": 1}, "q_HUbDH": {"answer": 5}}}
