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_1El4):
Calculate -3 + 9.

Question 1 (Question id: q_7h7UHD):
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 butterflys, 1 shrimp, 3 scorpions?
 Respond with an integer.

Question 2 (Question id: q_m6X6AU):
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: "their"

Question 3 (Question id: q_bc0tf):
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 3 butterflys, 1 snake, 3 ants, 2 leechs?
 Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

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.
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_1El4": {"answer": 6, "half_answer": 3}, "q_7h7UHD": {"answer": 46, "half_answer": 23}, "q_m6X6AU": {"answer": "r", "first_char": "r", "original_string": "their"}, "q_bc0tf": {"answer": 36, "half_answer": 18}}}
