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_V68vpI):
Calculate 1 - -7 - -5.

Question 1 (Question id: q_mSOwxm):
Solve for q: -6*q - 12 = -108 Respond with an integer.

Question 2 (Question id: q_7fqLmnxh):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 3 dogs, 1 spider, 2 beetles?
 Respond with an integer.

Question 3 (Question id: q_usl0FwjC):
Calculate 7 / 1.



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

Each key’s value must be an object holding an 'answer' field.
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.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Include 'num_questions_asked' to record the total number of questions presented.

Now provide the result JSON using the described format.
