Read the sentence. The invention of email opened an important epoch in the history of communication.
Which term can replace epoch without changing the meaning of this sentence? A.) calendar
B.) era
C.) millennium
D.) timeline

B. era

Explanation:

The word epoch means: a period of time in history.

We want to find a synonym for epoch, or a word that has the same meaning. So, if we were to replace epoch, the sentence would be the same.

Calendar: a chart showing the days, weeks and months of a year

Era: period of history that is long and distinct

Millennium: period of 1000 years

Timeline: a graphic representation of time passing

The word that makes the most sense as a synonym for epoch is era.

Therefore, the correct answer is B: era.
