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_Ov04):
Solve for n: 35 - 18*n = 17 Respond with an integer.

Question 1 (Question id: q_iC8LtNL):
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: "and"

Question 2 (Question id: q_sc3X1):
How many times does the letter "t" appear in the text: "the same"? 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 last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked: how many questions were asked in total.
• num_questions_answered: count of questions present in your JSON.

Now provide the result JSON using the described format.

{"ground_truth": {"q_Ov04": {"answer": 1}, "q_iC8LtNL": {"answer": "d", "original_string": "and"}, "q_sc3X1": {"answer": 1}, "global_metadata": {"num_questions_asked": 3, "num_questions_answered": 3}}}
