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_skTX3):
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: "often"

Question 1 (Question id: q_uGc6Tv):
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 woodlouses, 3 crickets, 2 shrimps, 4 leechs, 3 tigers?
 Respond with an integer.

Question 2 (Question id: q_uDJ0pNf):
How many times does the letter "a" appear in the text: "as to the"? Respond with an integer.



Return a JSON with each question id as a key.

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.
If the response to a question is a string, add a 'first_char' field containing its first character.
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.
• num_questions_answered: count of questions present in your JSON.

Now provide the result JSON using the described format.

{"ground_truth": {"q_skTX3": {"answer": "n", "first_char": "n", "original_string": "often"}, "q_uGc6Tv": {"answer": 78, "half_answer": 39}, "q_uDJ0pNf": {"answer": 1}, "global_metadata": {"num_questions_asked": 3, "num_questions_answered": 3}}}
