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_e94p1c):
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: "things"

Question 1 (Question id: q_MXkb):
Calculate 5 + 4.

Question 2 (Question id: q_qthJX):
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 lions, 2 cows, 3 shrimps, 4 praying mantiss, 4 crickets?
 Respond with an integer.

Question 3 (Question id: q_eLfQ):
How many times does the letter "i" appear in the text: "Now inform the"? Respond with an integer.

Question 4 (Question id: q_n4L6Q):
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: "participants"

Question 5 (Question id: q_g7NJr):
Calculate ( 9 / 9 ).



Output JSON where all question ids are keys, omitting q_e94p1c.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_g7NJr": {"answer": 1}, "q_n4L6Q": {"answer": "s", "first_char": "s", "original_string": "participants"}, "q_eLfQ": {"answer": 1}, "q_qthJX": {"answer": 102, "additional_answer_info": {"half_answer": 51, "double_answer": 204}}, "q_MXkb": {"answer": 9}}}
