Choose whether the following sentence is grammatically correct or incorrect. Marcos es tan guapo que tú.

The sentence is incorrect because comparisons of equality in Spanish use tan + adjective + como: “Marcos es tan guapo como tú” means “Marcos is as handsome as you.” Tan ... que is used for “so ... that,” usually followed by a result, so que does not fit this comparison.
