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_5cPMb):
Determine the value of i that satisfies: i - 12 = 4 Respond with an integer.

Question 1 (Question id: q_DFK1xsJ):
Find the value of a in the equation: 18*a + 3 = 309 Respond with an integer.

Question 2 (Question id: q_UDlB5P9):
Calculate 1 * 5.

Question 3 (Question id: q_YSJkNo):
Solve for l: 15*l + 8 = 173 Respond with an integer.

Question 4 (Question id: q_UgIhOC):
How many times does the letter "v" appear in the text: "advertisements When Mr"? Respond with an integer.



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.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
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.

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.

Now provide the result JSON using the described format.
