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_U3inKa9e):
Determine the value of p that satisfies: 14*p + 15 = 43 Respond with an integer.

Question 1 (Question id: q_DSQm):
Calculate 8 - -8.

Question 2 (Question id: q_ZKCqo):
How many times does the letter "k" appear in the text: "Gutenberg works 1"? Respond with an integer.



Output JSON where all question ids are keys, omitting q_U3inKa9e.

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.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_ZKCqo": {"answer": 1, "answer_type": "integer"}, "q_DSQm": {"answer": 16, "answer_type": "integer", "additional_answer_info": {"half_answer": 8, "double_answer": 32}}}}
