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_Ipgyx):
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: "so"

Question 1 (Question id: q_eMF8Tjq):
Find the value of q in the equation: 10*q = 200 Respond with an integer.

Question 2 (Question id: q_UT2V):
Determine the value of s that satisfies: 4 - 4*s = -76 Respond with an integer.



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

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 response to a question is a string, add a 'first_char' field containing its first character.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Add a top-level 'global_metadata' field that records overall stats:
Include 'num_questions_asked' to record the total number of questions presented.
• questions_with_integer_answers: ids of questions with integer replies.

Now provide the result JSON using the described format.
