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_9yvjNH):
Calculate 7 - -9 + 5.

Question 1 (Question id: q_09s94fj):
Calculate 3 - -1 / 1.

Question 2 (Question id: q_GVx00De):
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: "from"

Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to 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.

Now provide the result JSON using the described format.
