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_anfN):
Find the value of a in the equation: 19*a - 20 = 170 Respond with an integer.

Question 1 (Question id: q_CEHSEy9):
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: "talent"

Question 2 (Question id: q_JzfGOME5):
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 birds, 2 crabs, 2 praying mantiss, 4 lions?
 Respond with an integer.



Return a JSON with each question id (except for q_anfN) 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.

Add a top-level 'global_metadata' field that records overall stats:
Set 'num_questions_asked' to the count of questions originally displayed.
Record the answered-question count in the field 'num_questions_answered'.
Provide 'questions_with_integer_answers', listing ids with integer answers (or [] if no integers).

Now provide the result JSON using the described format.

{"ground_truth": {"q_CEHSEy9": {"answer": "t", "first_char": "t"}, "q_JzfGOME5": {"answer": 56, "additional_answer_info": {"half_answer": 28, "double_answer": 112}}, "global_metadata": {"num_questions_asked": 3, "num_questions_answered": 2, "questions_with_integer_answers": ["q_JzfGOME5"]}}}
