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_3opO):
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: "up"

Question 1 (Question id: q_q91e):
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 horses, 1 giraffe, 1 human?
 Respond with an integer.



Create a JSON object keyed by every question id except q_3opO.

Each key’s value must be an object holding an 'answer' field.
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.

Add a top-level 'global_metadata' field that records overall stats:
Set 'num_questions_asked' to the count of questions originally displayed.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

Now provide the result JSON using the described format.

{"ground_truth": {"q_q91e": {"answer": 22, "half_answer": 11}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": ["q_q91e"]}}}
