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_Idi4XN):
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: "environments"

Question 1 (Question id: q_kH2Zc7q6):
Calculate ( 2 + 4 ).

Question 2 (Question id: q_jnsLM9C0):
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: "something"



Output JSON where all question ids are keys, omitting q_Idi4XN.

Each key’s value must be an object holding an 'answer' field. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
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).
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_jnsLM9C0": {"answer": "g", "answer_type": "string", "first_char": "g"}, "q_kH2Zc7q6": {"answer": 6, "answer_type": "integer", "additional_answer_info": {"half_answer": 3, "double_answer": 12}}}}
