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_GtMOCP41):
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: "pollution"

Question 1 (Question id: q_wfWU):
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 chickens, 4 jellyfishs, 4 scorpions, 2 leechs?
 Respond with an integer.

Question 2 (Question id: q_H0X19CXy):
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: "the"



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).

Now provide the result JSON using the described format.

{"ground_truth": {"q_GtMOCP41": {"answer": "n", "answer_type": "string"}, "q_wfWU": {"answer": 40, "answer_type": "integer", "additional_answer_info": {"half_answer": 20, "double_answer": 80}}, "q_H0X19CXy": {"answer": "e", "answer_type": "string"}}}
