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_ETHOIrtR):
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: "are"

Question 1 (Question id: q_T5ar1):
How many times does the letter "n" appear in the text: "Why not"? Respond with an integer.

Question 2 (Question id: q_vuwiB):
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: "so"

Question 3 (Question id: q_QvQYdv0k):
How many times does the letter "n" appear in the text: "the machine deposited"? Respond with an integer.

Question 4 (Question id: q_9nY785a):
Calculate 8 / 1.

Question 5 (Question id: q_Ays6bA5):
How many times does the letter "a" appear in the text: "vibration of"? Respond with an integer.

Question 6 (Question id: q_thfcZ):
Determine the value of q that satisfies: 4*q + 24 = 104 Respond with an integer.

Question 7 (Question id: q_Ul9nc4):
How many times does the letter "i" appear in the text: "him for"? Respond with an integer.

Question 8 (Question id: q_vNd0v):

Question 9 (Question id: q_lRp4bz):
How many times does the letter "a" appear in the text: "that has"? Respond with an integer.



Output JSON where all question ids are keys, omitting q_Ays6bA5, q_QvQYdv0k, q_ETHOIrtR, q_T5ar1.

For every question id, supply an object whose 'answer' field stores the solution.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.
