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_Cqgjr):
Solve for w: 8 - 18*w = -208 Respond with an integer.

Question 1 (Question id: q_vdr0):
Find the value of q in the equation: 10*q = 200 Respond with an integer.

Question 2 (Question id: q_UcYlO):
How many times does the letter "o" appear in the text: "tired out"? Respond with an integer.

Question 3 (Question id: q_LFsntk):
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"



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

Each key’s value must be an object holding an 'answer' field.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_Cqgjr": {"answer": 12, "additional_answer_info": {"half_answer": 6, "double_answer": 24}}, "q_vdr0": {"answer": 20, "additional_answer_info": {"half_answer": 10, "double_answer": 40}}, "q_UcYlO": {"answer": 1}, "q_LFsntk": {"answer": "d", "first_char": "d"}}}
