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_yRpStBks):
How many times does the letter "r" appear in the text: "or using"? Respond with an integer.

Question 1 (Question id: q_6wcX):
Solve for e: 5*e - 17 = 83 Respond with an integer.

Question 2 (Question id: q_CSJRT):
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: "way"

Question 3 (Question id: q_JGCApNNG):
Calculate ( -1 - ( -3 / 3 ) ).



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
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).
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_yRpStBks": {"answer": 1}, "q_6wcX": {"answer": 20, "additional_answer_info": {"half_answer": 10, "double_answer": 40}}, "q_CSJRT": {"answer": "y", "first_char": "y", "original_string": "way"}, "q_JGCApNNG": {"answer": 0, "additional_answer_info": {"half_answer": 0, "double_answer": 0}}}}
