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_bjfck):
How many times does the letter "s" appear in the text: "eBooks may"? Respond with an integer.

Question 1 (Question id: q_mPfi):
Solve for p: 12*p + 15 = 51 Respond with an integer.

Question 2 (Question id: q_OnvxD1):
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: "story"

Question 3 (Question id: q_led1bFh):
Determine the value of q that satisfies: 171*q = 2394 Respond with an integer.



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

Each key’s value must be an object holding an 'answer' field.
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_OnvxD1": {"answer": "y", "answer_type": "string", "first_char": "y"}, "q_led1bFh": {"answer": 14, "answer_type": "integer", "additional_answer_info": {"half_answer": 7, "double_answer": 28}}, "q_bjfck": {"answer": 1, "answer_type": "integer"}}}
