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_wWvG):
Calculate 7 + 4 - 7.

Question 1 (Question id: q_U6kq5):
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: "up"

Question 2 (Question id: q_XKXjQg):
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"

Question 3 (Question id: q_MmDA9bfa):
Find the value of v in the equation: 10*v + 2 = 102 Respond with an integer.



Produce a JSON object whose top-level keys are the question ids.

For every question id, supply an object whose 'answer' field stores the solution.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
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.
Add 'num_questions_answered' showing how many questions you answered.

Now provide the result JSON using the described format.
