Question

Which statement correctly uses a description of time?

The invention of the automobile began a new millennium.
The expansion of railroads marked the start of a new era.
The time from 1980 to 1989 was a century of economic growth.
The years 1900 to 1999 were a decade filled with many political changes.

Answer 1

B- The expansion of railroads marked the start of a new era.

Step-by-step explanation:

Well it's not D because 100 years= century, not decade. That also means its not C either. That means we are now left with either A or B. I'm guessing it's B because it's more reasonable than A.

Hope this helps!
