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_JlTLrKN9):
Calculate 1 + ( 6 - 4 ).

Question 1 (Question id: q_qwceJpM):
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: "rankings"

Question 2 (Question id: q_DZaD16):
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 1 horse, 3 snakes, 1 wasp?
 Respond with an integer.

Question 3 (Question id: q_OMSzzkE):
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: "time"



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.
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

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.
