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_37wGl):
Calculate ( 6 * 8 ) + 3.

Question 1 (Question id: q_p5evIkYy):
How many times does the letter "t" appear in the text: "within 30 days"? Respond with an integer.



Return a JSON with each question id as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
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.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_37wGl": {"answer": 51}, "q_p5evIkYy": {"answer": 1}}}
