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_PerFq):
How many times does the letter "a" appear in the text: "a name"? Respond with an integer.

Question 1 (Question id: q_FfsZNEAE):
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: "critically"

Question 2 (Question id: q_j3HUf):
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: "choices"

Question 3 (Question id: q_UeBtwu):
Determine the value of v that satisfies: 44*v + 5 = 533 Respond with an integer.



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

The value for each key should be an object that contains the answer in the field 'answer'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.
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_j3HUf": {"answer": "s", "first_char": "s", "original_string": "choices"}, "q_PerFq": {"answer": 2, "additional_answer_info": {"half_answer": 1, "double_answer": 4}}, "q_UeBtwu": {"answer": 12, "additional_answer_info": {"half_answer": 6, "double_answer": 24}}}}
