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_rCGC6WmY):
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: "can"

Question 1 (Question id: q_ajhp):
Calculate ( ( 1 + 6 + 3 ) ).

Question 2 (Question id: q_hGgVLGLm):
How many times does the letter "i" appear in the text: "Now inform the"? Respond with an integer.



Output JSON where all question ids are keys, omitting q_rCGC6WmY.

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 last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_hGgVLGLm": {"answer": 1, "task_type": "letter_counting"}, "q_ajhp": {"answer": 10, "half_answer": 5}}}
