Decide whether the sentence is grammatically CORRECT or INCORRECT as written.
La silla es tan duro como la mesa.
Answer : Incorrect.
Explanation : In a sentence, the adjective must agree with the subject in gender and number. "Silla" is a singular feminine noun, so her adjective must be feminine singular too. It should be "dura".
And the whole sentence should be "La silla es tan dura como la mesa".
