the byzantine empire was established in 330 CE and fell in 1453 CE. according to the timeline, the empires reign took place during which two eras?

A) The classical era and postclassical

Explanation:

Since there is no timeline attached, I'm going to assume it is general history chronology.

Classical period (era) started in 8th century BC and lasted until 5th century AD. It is the period of Classical Antiquity.

Postclassical era comes after, as the name suggess. It lasted roughly from 5th until 15th century.

So, when Emperor Constantine establishe Eastern Roman Empire (Byzantine) in 330AD, that event belongs in classic era.

The fall of the Byzantine due to Ottomans, happened in 1453, in mid-15th century, which according to the timeline belongs in postclassical era.

type of error:

the error in the sentence is a "dangling modifier". a dangling modifier is a phrase, word or clause that "dangles" because there is not target to modify. in this case, "after mopping the floor" is the dangling modifier since it has no word to modify. the noun "house" cannot mop the floor; therefore there is a mistake in the writing of the sentence.
