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_18LGnf1w):
Calculate ( -2 / 1 ) - -5.

Question 1 (Question id: q_Vqpe):
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: "the"

Question 2 (Question id: q_BnXQUO):
Calculate 9 + -6.



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

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.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
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.

Add a top-level 'global_metadata' field that records overall stats:
Set 'num_questions_asked' to the count of questions originally displayed.
'num_questions_answered' must hold the number of answered questions.

Now provide the result JSON using the described format.
