which of the following pairs of modern nations occupy areas that were
once included in the roman empire?
1.india and egypt
2.norway and denmark
3.spain and england
4china and germany

Dear doublevision,

The answer is: 3.Spain and England.

As you can see on this map, the regions known as Spain and England
today were parts of the Roman Empire:

The other pairs of countries are impossible: While Egypt belonged to
the Roman Empire, India was out of reach for the Romans. Parts of
today's western, south-western and southern Germany were Roman
provinces, but China was hardly more than a rumor to the Ancient
Romans. And the Scandinavian region, to which Norway and Denmark
belong, have never been reached by the Roman legions.

Hope this answers your question!
Best regards,
