Wilson is suggesting that the day for spreading a nations influence as well as its size is long behind, stating that the prime time for the United States to spread influentially in Europe is no longer there. Or in another case no European nation should be able to spread conquest across the continent and that they had their chance. thats the best i can think of hope this helps
We don't have enough information to answer this question, but i believe what you're trying to find is that the Muslim armies carried their faith west across the top of the entire continent.
Hopes this helps, if it doesn't please add information onto your question, like example, the choices you were given.
Have a Good Day
