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_W9W8U):
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: "soil"

Question 1 (Question id: q_9tLiDAK):
How many times does the letter "u" appear in the text: "not uniform and"? Respond with an integer.

Question 2 (Question id: q_QxmCk0l):
How many times does the letter "r" appear in the text: "South for"? Respond with an integer.

Question 3 (Question id: q_qerJ):
Determine the value of i that satisfies: 4*i - 1 = 47 Respond with an integer.



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

For every question id, supply an object whose 'answer' field stores the solution.
For even integer answers, include 'half_answer' equal to answer ÷ 2.

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 – number you actually 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: maps each id to its integer answer
  • sum_of_answers: the combined total

Now provide the result JSON using the described format.
