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_DQwXY):
Calculate 9 + -1.

Question 1 (Question id: q_Ivw9):
Calculate ( -3 * -3 ).

Question 2 (Question id: q_Pqqz8PF):
Solve for a: 9*a - 16 = 83 Respond with an integer.

Question 3 (Question id: q_aqymFhK4):
How many times does the letter "g" appear in the text: "registered trademark"? Respond with an integer.

Question 4 (Question id: q_1CS9y6pZ):
Determine the value of x that satisfies: 2592*x = 2592 Respond with an integer.

Question 5 (Question id: q_Naqk):
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 grasshopper, 4 sea slugs, 2 beetles, 2 birds, 4 wasps?
 Respond with an integer.

Question 6 (Question id: q_nfctxb):
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 firefly, 3 praying mantiss, 4 horses, 4 elephants?
 Respond with an integer.

Question 7 (Question id: q_9YWoBl):
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: "to"



Your output must be a JSON mapping every question id to its answer info.

For every question id, supply an object whose 'answer' field stores the solution.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
