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_ZRiO9S):
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: "all"

Question 1 (Question id: q_0n8g8TV):
How many times does the letter "t" appear in the text: "to listen directly"? Respond with an integer.

Question 2 (Question id: q_N8LUJLF):
Find the value of x in the equation: 60*x - 220 = 860 Respond with an integer.



Create a JSON object keyed by every question id except q_ZRiO9S.

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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).

Now provide the result JSON using the described format.

{"ground_truth": {"q_N8LUJLF": {"answer": 18, "answer_type": "integer", "additional_answer_info": {"half_answer": 9, "double_answer": 36}}, "q_0n8g8TV": {"answer": 3, "answer_type": "integer"}}}
