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_a5ms4Rn):
Determine the value of v that satisfies: 28*v = 420 Respond with an integer.

Question 1 (Question id: q_WNnEiic8):
Calculate -1 * 0.

Question 2 (Question id: q_lFUfbt1):
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 2 scorpions, 3 insects, 4 cats, 3 snakes?
 Respond with an integer.



Return a JSON with each question id 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).
For string answers, include 'first_char' with the answer’s initial letter.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
'num_questions_asked' should equal the total questions that appeared.
• num_questions_answered: count of questions present in your JSON.
• questions_with_integer_answers – list of question ids whose answers are integers (empty list if none).

Now provide the result JSON using the described format.
