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_UxBj50xt):
Determine the value of n that satisfies: 12 - 16*n = -100 Respond with an integer.

Question 1 (Question id: q_kFwIR9):
How many times does the letter "e" appear in the text: "medium and"? Respond with an integer.

Question 2 (Question id: q_3DimD):
Determine the value of u that satisfies: 44*u + 5 = 841 Respond with an integer.

Question 3 (Question id: q_oPIZtjBX):
Find the value of d in the equation: 50 - 12*d = -130 Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

For every question id, supply an object whose 'answer' field stores the solution.
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.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Now provide the result JSON using the described format.
