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_xkxleMM8):
How many times does the letter "o" appear in the text: "for the whole"? Respond with an integer.

Question 1 (Question id: q_fU2ue):
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: "understand"

Question 2 (Question id: q_YdyMn):
How many times does the letter "h" appear in the text: "their air"? Respond with an integer.

Question 3 (Question id: q_pwVCqpuE):
Solve for x: 11*x - 8 = 25 Respond with an integer.



Create a JSON object keyed by every question id except q_fU2ue.

Each key’s value must be an object holding an 'answer' field.
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.
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_pwVCqpuE": {"answer": 3}, "q_YdyMn": {"answer": 1}, "q_xkxleMM8": {"answer": 2, "half_answer": 1}}}
