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_FY4v5VN):
Solve for k: 30*k = 300 Respond with an integer.

Question 1 (Question id: q_f8ljkO):
How many times does the letter "c" appear in the text: "A campaign"? Respond with an integer.

Question 2 (Question id: q_irJS):
Calculate -3 * -9.

Question 3 (Question id: q_f8ljkO):
How many times does the letter "c" appear in the text: "A campaign"? Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.
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.
Provide 'questions_with_integer_answers', listing ids with integer answers (or [] if no integers).

Now provide the result JSON using the described format.

{"ground_truth": {"q_FY4v5VN": {"answer": 10, "half_answer": 5}, "q_f8ljkO": {"answer": 1}, "q_irJS": {"answer": 27}, "global_metadata": {"num_questions_asked": 4, "questions_with_integer_answers": ["q_FY4v5VN", "q_f8ljkO", "q_irJS", "q_f8ljkO"]}}}
