Question

Choose the sentence that uses abbreviations correctly.

a) The archeologists reported that some of the newly discovered remains dated back to AD 200, but others were from the time
before Christ.

b) The archeologists reported that some of the newly discovered remains dated back to AD 200, but others were from the BC era.

c) The archeologists reported that some of the newly discovered remains dated back to 200 AD, but others were from the BC era.

Answer 1

The sentence that uses abbreviations correctly is:

c) The archaeologists reported that some of the newly discovered remains dated back to 200 AD, but others were from the BC era.

Answer 2

Option b is the sentence that correctly abbreviates each time label.

Traditionally in English AD is placed before the time, while BC is placed after the time.

example:

AD: 200

200 BC

BC is also usually stated abbreviated rather that stated as "before Christ," unless you are referring to what it stands for or what it means.
