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_h8i16sb2):
Calculate -3 * 1 * -5.

Question 1 (Question id: q_vMQrbc):
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: "how"

Question 2 (Question id: q_b9at):
How many times does the letter "r" appear in the text: "miles or so"? Respond with an integer.

Question 3 (Question id: q_XbpshhEl):
Calculate ( 1 * 8 ).

Question 4 (Question id: q_LDuX88J):
How many times does the letter "o" appear in the text: "you received the"? Respond with an integer.



Create a JSON object keyed by every question id except q_LDuX88J.

For every question id, supply an object whose 'answer' field stores the solution.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
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_XbpshhEl": {"answer": 8, "answer_type": "integer", "additional_answer_info": {"half_answer": 4, "double_answer": 16}}, "q_vMQrbc": {"answer": "w", "answer_type": "string", "first_char": "w", "original_string": "how"}, "q_h8i16sb2": {"answer": 15, "answer_type": "integer"}, "q_b9at": {"answer": 1, "answer_type": "integer"}}}
