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_a1ywuAO):
How many times does the letter "n" appear in the text: "this agreement"? Respond with an integer.

Question 1 (Question id: q_WHHcZ):
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 cockroachs, 1 insect, 1 tiger?
 Respond with an integer.

Question 2 (Question id: q_RUwcT3):
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: "really"



Output JSON where all question ids are keys, omitting q_WHHcZ.

For every question id, supply an object whose 'answer' field stores the solution.
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.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_a1ywuAO": {"answer": 1}, "q_RUwcT3": {"answer": "y", "first_char": "y", "original_string": "really"}, "global_metadata": {"num_questions_asked": 3, "questions_with_integer_answers": ["q_a1ywuAO"]}}}
