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

Question 1 (Question id: q_lxNCAlz):
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: "that"



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

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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_lxNCAlz": {"answer": "t", "first_char": "t"}}}
