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_ghwFaZ):
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: "involve"

Question 1 (Question id: q_0R3K):
Calculate -9 * -9 + 3.

Question 2 (Question id: q_aafPn):
How many times does the letter "i" appear in the text: "is of"? Respond with an integer.



Return a JSON with each question id (except for q_ghwFaZ) as a key.

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

Attach a 'combined_results' object that contains:
  • 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_0R3K": {"answer": 84, "half_answer": 42}, "q_aafPn": {"answer": 1}, "global_metadata": {"num_questions_asked": 3}, "combined_results": {"integer_info": {"q_0R3K": 84, "q_aafPn": 1}, "sum_of_answers": 85}}}
