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_aS2ar):
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"

Question 1 (Question id: q_P1Cf):
Calculate 8 + 8 - 2.

Question 2 (Question id: q_LOgYC):
Find the value of h in the equation: 72*h + 162 = 450 Respond with an integer.

Question 3 (Question id: q_UvZx):
Calculate -2 + 9 - -6.

Question 4 (Question id: q_6vmom):
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: "parts"



Produce a JSON object whose top-level keys are the question ids.

Each key’s value must be an object holding an 'answer' field.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
Include 'num_questions_asked' to record the total number of questions presented.
• num_questions_answered: count of questions present in your JSON.

Attach a 'combined_results' object that contains:
  • integer_info (id → integer answer)
  • sum_of_answers (sum of those integers)

Now provide the result JSON using the described format.
