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_dWoq1mg):
Determine the value of f that satisfies: 14*f + 31 = 115 Respond with an integer.

Question 1 (Question id: q_wep5cPC):
How many times does the letter "a" appear in the text: "has enabled him"? Respond with an integer.



Output JSON where all question ids are keys, omitting q_dWoq1mg.

The value for each key should be an object that contains the answer in the field 'answer'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each 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.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_wep5cPC": {"answer": 2, "answer_type": "integer", "additional_answer_info": {"half_answer": 1, "double_answer": 4}}}}
