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_zDpBgeF):
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: "study"

Question 1 (Question id: q_YVRtfD):
Calculate ( 4 - -4 + -6 ).

Question 2 (Question id: q_wc7l):
Calculate 5 - -8.

Question 3 (Question id: q_8JXB0bj):
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: "fairly"



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'.
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.
If the response to a question is a string, add a 'first_char' field containing its first character.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Include 'num_questions_asked' to record the total number of questions presented.
Add 'num_questions_answered' showing how many questions you answered.

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.
