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_rKDYXUUA):
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: "are"

Question 1 (Question id: q_DJL3):
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 dogs, 1 flatworm, 4 praying mantiss, 3 woodlouses?
 Respond with an integer.

Question 2 (Question id: q_H82an):
How many times does the letter "e" appear in the text: "Yes was"? 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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_rKDYXUUA": {"answer": "e", "first_char": "e"}, "q_DJL3": {"answer": 74, "half_answer": 37}, "q_H82an": {"answer": 1}}}
