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_ZgeFAM):
Calculate 7 * 6.

Question 1 (Question id: q_6HH7N):
Calculate ( ( 5 + 1 ) ).

Question 2 (Question id: q_0Tqn3B):
Calculate ( ( 0 - -9 ) ).

Question 3 (Question id: q_VTFE4TRs):
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: "some"



Output JSON where all question ids are keys, omitting q_6HH7N.

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

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.
Record the answered-question count in the field 'num_questions_answered'.

Now provide the result JSON using the described format.

{"ground_truth": {"q_0Tqn3B": {"answer": 9}, "q_VTFE4TRs": {"answer": "e"}, "q_ZgeFAM": {"answer": 42, "half_answer": 21}, "global_metadata": {"num_questions_asked": 4, "num_questions_answered": 3}}}
