Question 2 (Question id: q_F2fh3SQI):
Calculate 6 - -2 / 1.

Question 3 (Question id: q_f4yEK):
Calculate -9 * -4.

Question 4 (Question id: q_oGHjL4):
Calculate ( -6 + 8 ).

Question 5 (Question id: q_Rm29mhj):
Calculate ( ( 1 - 1 ) ).

Question 6 (Question id: q_YRLNakMF):
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: "organisms"

Question 7 (Question id: q_zIC9):
Calculate -1 - ( ( ( -5 / 1 ) ) ).

Question 8 (Question id: q_AHVCZnsC):
Calculate ( ( -8 * -7 ) ) * 2.

Question 9 (Question id: q_9II3Ns9A):
How many times does the letter "f" appear in the text: "Mars of any"? Respond with an integer.

Create a JSON object keyed by every question id except q_h7NDhB0.

For every question id, supply an object whose 'answer' field stores the solution.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
Provide 'questions_with_integer_answers', listing ids with integer answers (or [] if no integers).

Now provide the result JSON using the described format.
