Answer 1

If you want to default the values in your options hash, you want to merge the defaults in your function. If you put the defaults in the default parameter itself, it'll be over-written:

def my_info(name, options = {})
  options.reverse_merge!(age: 27, weight: 160, city: "New York")

  ...
end
