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_Gdmd):
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 1 (Question id: q_fzvZDCE):
Calculate -5 * -3 + -4.

Question 2 (Question id: q_zZD8):
Find the value of p in the equation: 12*p + 2 = 74 Respond with an integer.

Question 3 (Question id: q_ntwS):
Calculate 2 - 6 - -9.

Question 4 (Question id: q_KNRb):
Determine the value of g that satisfies: 48*g - 15 = 465 Respond with an integer.

Question 5 (Question id: q_zgoYo):
Solve for q: 17*q + 10 = 231 Respond with an integer.

Question 6 (Question id: q_RNiO):
Solve for q: 260*q - 480 = 560 Respond with an integer.

Question 7 (Question id: q_Yw1SSZwC):
Solve for a: 9*a - 16 = 83 Respond with an integer.



Return a JSON with each question id as a key.

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.
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 response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
