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_FcMKijK):
Calculate ( 7 * 9 + 0 ).

Question 1 (Question id: q_N2Px):
Find the value of f in the equation: -5*f - 30 = -70 Respond with an integer.



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

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Include 'num_questions_asked' to record the total number of questions presented.

Now provide the result JSON using the described format.

{"ground_truth": {"q_N2Px": {"answer": 8, "half_answer": 4}, "global_metadata": {"num_questions_asked": 2}}}
