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_xoJDZOo):
Find the value of t in the equation: 11*t + 1 = 111 Respond with an integer.

Question 1 (Question id: q_qtgsBe):
Determine the value of a that satisfies: 15 - 4*a = -21 Respond with an integer.

Question 2 (Question id: q_xaHIPsuk):
Determine the value of x that satisfies: 2592*x = 2592 Respond with an integer.

Question 3 (Question id: q_4HML):
Find the value of w in the equation: 3 - 6*w = -9 Respond with an integer.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
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.
If the response to a question is a string, add a 'first_char' field containing its first character.
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.

Now provide the result JSON using the described format.
