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_N1TjDXi):
Calculate -5 - -8 + 3.

Question 1 (Question id: q_OIqcXa):
Solve for t: 18*t + 28 = 226 Respond with an integer.

Question 2 (Question id: q_Lons):
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: "teaches"



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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For string answers, include 'first_char' with the answer’s initial letter.
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.

In addition, add 'combined_results' with:
  • integer_info – object mapping ids to their integer answers
  • sum_of_answers – sum of those integers

Now provide the result JSON using the described format.
