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_U1Pj0Lc):
Find the value of u in the equation: 90*u - 6 = 1074 Respond with an integer.

Question 1 (Question id: q_RfahX):
Calculate -6 + 6 + 2.

Question 2 (Question id: q_BEzhB):
Calculate 1 + 2.

Question 3 (Question id: q_YSNn2Gp):
Calculate ( 6 - -8 ).



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

For every question id, supply an object whose 'answer' field stores the solution. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.

Now provide the result JSON using the described format.
