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_KfPuTP8R):
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: "far"

Question 1 (Question id: q_WwL1H):
Find the value of i in the equation: 307 - 14*i = 125 Respond with an integer.



Return a JSON with each question id as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked: how many questions were asked in total.
'num_questions_answered' must hold the number of answered questions.
• questions_with_integer_answers: ids of questions with integer replies.

Also include 'combined_results' consisting of:
  • integer_info – object mapping ids to their integer answers
  • sum_of_answers – sum of those integers

Now provide the result JSON using the described format.
