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_J6fNBs):
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: "each"

Question 1 (Question id: q_F7cB):
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 1 giraffe, 4 starfishs, 4 lobsters, 1 leech, 3 butterflys?
 Respond with an integer.

Question 2 (Question id: q_wma7gZEJ):
How many times does the letter "e" appear in the text: "door entreating"? Respond with an integer.



Return a JSON with each question id (except for q_J6fNBs) as a key.

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.

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

Now provide the result JSON using the described format.

{"ground_truth": {"q_wma7gZEJ": {"answer": 2, "half_answer": 1}, "q_F7cB": {"answer": 82, "half_answer": 41}, "global_metadata": {"num_questions_asked": 3, "num_questions_answered": 2}}}
