Based on the information typically associated with World War I, the correct statements from your options would likely be:
-
The Russians lacked the technology to fight successfully against more technologically advanced nations.
This reflects the reality that Russia faced significant disadvantages due to outdated equipment and technology compared to other nations. -
The Central Powers suffered more casualties than the British Empire and the United States.
Historical data indicates that the Central Powers, particularly Germany and Austria-Hungary, had very high casualty rates.
The other statements are not supported by historical evidence: the French were also technologically advanced, and the British Empire indeed fought on land, not just at sea.
