What kind of scoping ruby use, even if it has lots of scoping rules
which was supported by adding different parameters infront of variable
names and using different character size. We do not decide what kind of
scoping does Ruby use? Dynamic or static scoping. Thank you in advance.

Ruby uses static scoping in the basic syntax, however the use of eval with
a binding, or instance_eval (even when hidden very deep in other
methods) can change the context in which a block or string of code is
evaluated, causing it to have different scoping from the surrounding code
(but still static).
