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_bPNFeo):
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: "understand"

Question 1 (Question id: q_VFnpEsr1):
Determine the value of v that satisfies: 44*v + 5 = 533 Respond with an integer.

Question 2 (Question id: q_WUUoW):
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 leechs, 3 praying mantiss, 1 beetle, 2 scorpions, 2 crickets?
 Respond with an integer.

Question 3 (Question id: q_20jb):
How many times does the letter "t" appear in the text: "a mighty"? Respond with an integer.

Question 4 (Question id: q_wHB4ds):
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: "it"

Question 5 (Question id: q_Y8K8):
Solve for f: -4*f - 15 = -31 Respond with an integer.

Question 6 (Question id: q_bqv37hz):
Find the value of m in the equation: 35*m = 245 Respond with an integer.

Question 7 (Question id: q_WtSusCO):
Calculate 5 - 4.



Return a JSON with each question id as a key.

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.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
'num_questions_asked' should equal the total questions that appeared.

Now provide the result JSON using the described format.
