criminals to Australia

[sonu_gmat]

As 'during' should be used with definite time frame what is wrong in the following sentence since it specifies the time 100 years from 1788. Am I missing sth here.

During a hundred years, a period beginning in 1788, England exiled some 160,000 criminals to Australia.

Thanks in advance.

"during a hundred years" does not actually describe a specific time. You have the length of the time period, but you have not yet described when that period was. Including this after the fact does not help much, because "a period..." comes as a modifier set off by commas, even though this info is vital.

I would prefer: "During the hundred-year period beginning in 1788, ..."
