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_8FgXPX3):
Calculate 5 * 2 * 8.

Question 1 (Question id: q_rhNYEE4X):
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: "full"

Question 2 (Question id: q_A0BMXTiM):
How many times does the letter "s" appear in the text: "is not"? Respond with an integer.

Question 3 (Question id: q_IbqFmV):
How many times does the letter "t" appear in the text: "a waterfall a"? Respond with an integer.

Question 4 (Question id: q_4rNeDy):
Determine the value of a that satisfies: 26*a = 494 Respond with an integer.

Question 5 (Question id: q_O0EOx2):
Solve for m: -30*m - 2 = -542 Respond with an integer.

Question 6 (Question id: q_aGDisCm4):
Solve for x: 20*x + 1 = 301 Respond with an integer.

Question 7 (Question id: q_WKiZZIY4):
Calculate -3 + 0 - -7.

Question 8 (Question id: q_uX2y):
Solve for x: 12*x + 21 = 117 Respond with an integer.



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 string answers, include 'first_char' with the answer’s initial letter.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Include 'num_questions_asked' to record the total number of questions presented.
Add 'num_questions_answered' showing how many questions you answered.
• questions_with_integer_answers – list of question ids whose answers are integers (empty list if none).

Insert 'combined_results', which should hold:
  • integer_info – object mapping ids to their integer answers
  • sum_of_answers – sum of those integers

Now provide the result JSON using the described format.
