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_H8H7Eh4):
Determine the value of y that satisfies: 342*y - 4 = 2732 Respond with an integer.

Question 1 (Question id: q_Q9EmGG8E):
Solve for d: 20 - 15*d = -160 Respond with an integer.

Question 2 (Question id: q_XC3Ryz):
Determine the value of i that satisfies: 16*i + 20 = 84 Respond with an integer.

Question 3 (Question id: q_ZVYV):
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: "and"



Output JSON where all question ids are keys, omitting q_Q9EmGG8E.

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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:
• num_questions_asked: how many questions were asked in total.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Insert 'combined_results', which should hold:
  • integer_info (id → integer answer)
  • sum_of_answers (sum of those integers)

Now provide the result JSON using the described format.
