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_p2yJD):
Find the value of d in the equation: 216*d - 2 = 3670 Respond with an integer.

Question 1 (Question id: q_ybQxOD):
How many times does the letter "i" appear in the text: "and again"? Respond with an integer.

Question 2 (Question id: q_QsJYeGAX):
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: "this"

Question 3 (Question id: q_3NyvKl):
Find the value of x in the equation: 11*x - 11 = 11 Respond with an integer.



Create a JSON object keyed by every question id except q_p2yJD.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.

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.
• questions_with_integer_answers – list of question ids whose answers are integers (empty list if none).

Also include 'combined_results' consisting of:
  • integer_info: maps each id to its integer answer
  • sum_of_answers: the combined total

Now provide the result JSON using the described format.
