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_4nrTvrJ):
Calculate ( ( 7 - -3 ) ) - 7.

Question 1 (Question id: q_fT6AZoJU):
Calculate ( 0 + 6 ).

Question 2 (Question id: q_H45GpT):
Calculate ( 4 * 2 ) / 4.

Question 3 (Question id: q_hlgObU4):
Calculate 0 + 2.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
