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_RVYU):
How many times does the letter "u" appear in the text: "the use of"? Respond with an integer.

Question 1 (Question id: q_7KJXIo4):
How many times does the letter "f" appear in the text: "days following each"? Respond with an integer.

Question 2 (Question id: q_fVEupi1Z):
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: "and"

Question 3 (Question id: q_xsAM6R8D):
Determine the value of e that satisfies: e + 19 = 39 Respond with an integer.

Question 4 (Question id: q_Gn4q):
Solve for v: 15*v - 10 = 230 Respond with an integer.

Question 5 (Question id: q_A0to7As):
How many times does the letter "r" appear in the text: "order to"? Respond with an integer.

Question 6 (Question id: q_SXtE4hbz):
Find the value of m in the equation: 35*m = 245 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.
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).
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.
