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_LjiKNlo):
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 dogs, 4 humans, 3 lions?
 Respond with an integer.

Question 1 (Question id: q_WQjF):
How many times does the letter "v" appear in the text: "not believe"? Respond with an integer.

Question 2 (Question id: q_I4eu):
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: "and"



Your output must be a JSON mapping every question id to its answer info.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.

Now provide the result JSON using the described format.

{"ground_truth": {"q_LjiKNlo": {"answer": 28, "half_answer": 14}, "q_WQjF": {"answer": 1}, "q_I4eu": {"answer": "d", "first_char": "d", "original_string": "and"}, "global_metadata": {"num_questions_asked": 3}}}
