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_NRC8Ps1M):
Calculate 2 / 2 + 4.

Question 1 (Question id: q_spiWTC):
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: "things"



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

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

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.

Create a 'combined_results' section featuring:
  • integer_info holds all integer answers by id
  • sum_of_answers is their sum

Now provide the result JSON using the described format.

{"ground_truth": {"q_NRC8Ps1M": {"answer": 5, "answer_type": "integer"}, "q_spiWTC": {"answer": "s", "answer_type": "string"}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 2}, "combined_results": {"integer_info": {"q_NRC8Ps1M": 5}, "sum_of_answers": 5}}}
