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_pDohAV):
How many times does the letter "f" appear in the text: "Verne End of"? Respond with an integer.

Question 1 (Question id: q_GxnvQiye):
Determine the value of j that satisfies: 2 - 4*j = -22 Respond with an integer.

Question 2 (Question id: q_M9YBH):
How many times does the letter "k" appear in the text: "Gutenberg eBooks"? Respond with an integer.

Question 3 (Question id: q_zcXIrk):
How many times does the letter "d" appear in the text: "the United"? Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
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.
