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_BCN6i4P9):
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"

Question 1 (Question id: q_w64DgR):
How many times does the letter "t" appear in the text: "sitting with"? Respond with an integer.

Question 2 (Question id: q_57gM):
Calculate -3 * 1 * -8.

Question 3 (Question id: q_54TIwDe1):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 4 bees, 2 scorpions, 2 crabs?
 Respond with an integer.

Question 4 (Question id: q_TqwaYVY):
How many times does the letter "i" appear in the text: "of the experiment"? Respond with an integer.

Question 5 (Question id: q_Mz9T7gwE):
Find the value of h in the equation: 29 - 2*h = -11 Respond with an integer.

Question 6 (Question id: q_A7xw):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 2 tigers, 4 cockroachs, 4 crickets, 3 snakes?
 Respond with an integer.

Question 7 (Question id: q_lMk19x):
Calculate 1 - -9.

Question 8 (Question id: q_dxwMa):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 1 wasp, 2 bees, 2 tigers, 4 elephants?
 Respond with an integer.

Question 9 (Question id: q_Xn5a):
Find the value of i in the equation: 51*i = 102 Respond with an integer.

Question 10 (Question id: q_Fh9D):
Solve for n: -11*n - 8 = -173 Respond with an integer.



Output JSON where all question ids are keys, omitting q_lMk19x, q_A7xw, q_dxwMa.

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