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_I3eoJ):
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: "when"

Question 1 (Question id: q_Ix0Dhq):
How many times does the letter "r" appear in the text: "to Centropolis"? Respond with an integer.

Question 2 (Question id: q_LI7agAz0):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 1 tiger, 4 snakes, 4 cats?
 Respond with an integer.

Question 3 (Question id: q_PnqbtGH):
How many times does the letter "a" appear in the text: "but can"? Respond with an integer.



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

The value for each key should be an object that contains the answer in the field 'answer'.
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.

In addition, add 'combined_results' with:
  • 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.

{"ground_truth": {"q_I3eoJ": {"answer": "n"}, "q_Ix0Dhq": {"answer": 1}, "q_LI7agAz0": {"answer": 20, "half_answer": 10}, "q_PnqbtGH": {"answer": 1}, "global_metadata": {"num_questions_asked": 4}, "combined_results": {"integer_info": {"q_Ix0Dhq": 1, "q_LI7agAz0": 20, "q_PnqbtGH": 1}, "sum_of_answers": 22}}}
