Why is SO3 considered to be a Lewis Acid?

I don't know the precise answer, but on page 469 of the textbook it says that metals form basic oxides, while nonmetals (like sulfur) form acidic oxides.

A Lewis Acid is a species that accepts an electron pair because it will form another bond. Electrons are drawn towards the electronegative oxygen which makes the species act like a Lewis Acid.

Sulfur generally accepts a lone pair from another molecule or atom, which is why it is usually considered a lewis acid.

This question is asking to determine whether the oxides are acidic, basic, or amphoteric. How exactly do you determine/ figure that out?
a)BaO
b)SO3
c)As2O3
d)Bi2O3
