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_dXDxZ):
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: "and"

Question 1 (Question id: q_lxY5TK):
Solve for b: -19*b - 27 = -274 Respond with an integer.

Question 2 (Question id: q_BiRg):
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: "one"



Create a JSON object keyed by every question id except q_lxY5TK.

The value for each key should be an object that contains the answer in the field 'answer'. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each 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_BiRg": {"answer": "e", "answer_type": "string"}, "q_dXDxZ": {"answer": "d", "answer_type": "string"}}}
