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_X1hWvB):
Solve for f: 13 - 5*f = -22 Respond with an integer.

Question 1 (Question id: q_z8qW3YH):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 4 lions, 2 sea slugs, 2 grasshoppers, 3 ducks?
 Respond with an integer.

Question 2 (Question id: q_V7JzfP8C):
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: "their"

Question 3 (Question id: q_CO5lNr):
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: "and"



Create a JSON object keyed by every question id except q_V7JzfP8C.

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).

Now provide the result JSON using the described format.

{"ground_truth": {"q_CO5lNr": {"answer": "d"}, "q_X1hWvB": {"answer": 7}, "q_z8qW3YH": {"answer": 34, "additional_answer_info": {"half_answer": 17, "double_answer": 68}}}}
