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_aFibANk):
Find the value of n in the equation: 10 - 10*n = -10 Respond with an integer.

Question 1 (Question id: q_C7u88):
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: "people"

Question 2 (Question id: q_6b5pk):
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: "moves"

Question 3 (Question id: q_ymaryk):
How many times does the letter "o" appear in the text: "to scientific"? Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
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).
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_aFibANk": {"answer": 2, "additional_answer_info": {"half_answer": 1, "double_answer": 4}}, "q_C7u88": {"answer": "e", "first_char": "e", "original_string": "people"}, "q_6b5pk": {"answer": "s", "first_char": "s", "original_string": "moves"}, "q_ymaryk": {"answer": 1}}}
