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_Qhf2N):
Calculate 7 - -9 + 5.

Question 1 (Question id: q_JAucR):
Calculate -2 * -4.

Question 2 (Question id: q_BWz6):
Calculate 4 + 3.

Question 3 (Question id: q_BRIKwIl):
Determine the value of p that satisfies: 18*p - 16 = 56 Respond with an integer.

Question 4 (Question id: q_EcTnKiOf):
Calculate 8 / 8.

Question 5 (Question id: q_NjQgCv):
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: "thing"

Question 6 (Question id: q_DK4T):
Determine the value of v that satisfies: 40 - 360*v = -320 Respond with an integer.

Question 7 (Question id: q_M0ufU8u9):
How many times does the letter "n" appear in the text: "in the"? Respond with an integer.

Question 8 (Question id: q_C3ZB8oBq):
Determine the value of w that satisfies: 8*w - 13 = 147 Respond with an integer.

Question 9 (Question id: q_pr6Kz5):
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: "like"

Question 10 (Question id: q_Scyyg1):
Calculate 9 - 1.



Output JSON where all question ids are keys, omitting q_DK4T, q_BRIKwIl.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.
Add 'num_questions_answered' showing how many questions you answered.

Now provide the result JSON using the described format.
