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_kn68):
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: "feels"

Question 1 (Question id: q_rH0eld7f):
Calculate 7 + -7.

Question 2 (Question id: q_8Suq):
How many times does the letter "o" appear in the text: "then of"? Respond with an integer.

Question 3 (Question id: q_a2kW):
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: "not"



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'.
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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Set 'num_questions_asked' to the count of questions originally displayed.
Record the answered-question count in the field 'num_questions_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 holds all integer answers by id
  • sum_of_answers is their sum

Now provide the result JSON using the described format.
