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_OfENg):
Solve for c: 13 - 19*c = -196 Respond with an integer.

Question 1 (Question id: q_QzJLz):
Calculate ( ( 5 + -3 ) ).

Question 2 (Question id: q_TwsRFFq):
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: "how"

Question 3 (Question id: q_k6N5):
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: "time"



Produce a JSON object whose top-level keys are the question ids.

For every question id, supply an object whose 'answer' field stores the solution.
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).
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_OfENg": {"answer": 11}, "q_QzJLz": {"answer": 2, "additional_answer_info": {"half_answer": 1, "double_answer": 4}}, "q_TwsRFFq": {"answer": "w", "original_string": "how"}, "q_k6N5": {"answer": "e", "original_string": "time"}}}
