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_xB16n):
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: "medicine"

Question 1 (Question id: q_AiQjR):
Calculate 5 + 4.

Question 2 (Question id: q_TzBIGOD):
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: "opportunity"

Question 3 (Question id: q_NVflKb):
Calculate ( 4 / 2 ).



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

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.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
• num_questions_answered – number you actually answered.
• questions_with_integer_answers – list of question ids whose answers are integers (empty list if none).

Attach a 'combined_results' object that contains:
  • integer_info (id → integer answer)
  • sum_of_answers (sum of those integers)

Now provide the result JSON using the described format.
