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_18yA8):
Find the value of f in the equation: 170*f + 9 = 1029 Respond with an integer.

Question 1 (Question id: q_BRCsY):
Find the value of r in the equation: 40*r = 120 Respond with an integer.

Question 2 (Question id: q_8SB2P):
Solve for v: 5*v - 22 = -17 Respond with an integer.

Question 3 (Question id: q_FYtR2aQ):
Solve for k: 3*k + 6 = 60 Respond with an integer.

Question 4 (Question id: q_NqaCFn0B):
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: "change"

Question 5 (Question id: q_7FZK):
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: "our"

Question 6 (Question id: q_eQSFlB):
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: "is"



Return a JSON with each question id (except for q_8SB2P, q_BRCsY) as a key.

For every question id, supply an object whose 'answer' field stores the solution.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked: how many questions were asked in total.
Add 'num_questions_answered' showing how many questions you answered.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

In addition, add 'combined_results' with:
  • integer_info (id → integer answer)
  • sum_of_answers (sum of those integers)

Now provide the result JSON using the described format.
