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_OjRvbeq):
How many times does the letter "o" appear in the text: "that the famous"? Respond with an integer.

Question 1 (Question id: q_dQB6):
Calculate -2 - -5.

Question 2 (Question id: q_W3J4s):
Calculate ( ( -4 + 4 ) ).

Question 3 (Question id: q_F6607X):
Find the value of d in the equation: 12*d - 1 = 191 Respond with an integer.

Question 4 (Question id: q_1M6X7):
Determine the value of d that satisfies: 7*d + 13 = 90 Respond with an integer.

Question 5 (Question id: q_htrT3):
Calculate 5 * 5.

Question 6 (Question id: q_NzI3):
Find the value of g in the equation: 114*g + 57 = 2109 Respond with an integer.

Question 7 (Question id: q_Xh6Ec9Tb):
Solve for d: 20 - 15*d = -160 Respond with an integer.

Question 8 (Question id: q_4OCEA):
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: "for"



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
