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_qs7c6):
Find the value of y in the equation: 21*y + 2 = 296 Respond with an integer.

Question 1 (Question id: q_Bibn):
How many times does the letter "s" appear in the text: "work is"? Respond with an integer.

Question 2 (Question id: q_0n90eBki):
Solve for v: 4160*v = 33280 Respond with an integer.

Question 3 (Question id: q_W6zAte0i):
How many times does the letter "i" appear in the text: "and credit"? Respond with an integer.

Question 4 (Question id: q_Tb6h9Q):
Calculate 3 / 3.

Question 5 (Question id: q_Dging):
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: "pollution"

Question 6 (Question id: q_EEjWi):
How many times does the letter "h" appear in the text: "with a"? Respond with an integer.

Question 7 (Question id: q_lpkMlC):
Calculate 7 + 1 + -6.



Output JSON where all question ids are keys, omitting q_0n90eBki.

Each key’s value must be an object holding an 'answer' field.
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.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

Now provide the result JSON using the described format.
