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_9vi48):
How many times does the letter "w" appear in the text: "work and"? Respond with an integer.

Question 1 (Question id: q_0VD9L):
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 4 dogs, 2 horses, 1 praying mantis, 3 cockroachs?
 Respond with an integer.

Question 2 (Question id: q_bdqVO0):
Calculate ( ( -4 * -1 ) ).



Return a JSON with each question id (except for q_0VD9L) as a key.

Each key’s value must be an object holding an 'answer' field.
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).
If the response to a question is a string, add a 'first_char' field containing its first character.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
'num_questions_asked' should equal the total questions that appeared.
Add 'num_questions_answered' showing how many questions you answered.

Now provide the result JSON using the described format.
