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_Ymkd):
Calculate 8 * 1.

Question 1 (Question id: q_I7WPy):
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: "market"

Question 2 (Question id: q_kFRm):
How many times does the letter "a" appear in the text: "s audience was"? Respond with an integer.



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

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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_Ymkd": {"answer": 8, "answer_type": "integer", "half_answer": 4}, "q_I7WPy": {"answer": "t", "answer_type": "string"}}}
