I think it would be likely. Britain is a country that is well-developed and has a decent military. If you are referring to war in London or other big cities, I think the armies would try to keep warfare on the battlefield, not urban areas. However, to counter that, (correct me if I'm wrong), I believe London is on the water, so a type of naval invasion would be likely. It also depends on who the fighters are. Britain v. U.S.A. for example, evacuations of cities would begin, and it's likely we'd see another Refugee Crisis like the one happening now in Europe, but smaller. But the U.K is part of the U.N., a huge group of unified countries. If war were to break out, it's likely forces would be pushed out easily with the help of other powers/countries.
Dialogue can show the reader how the character thinks, interacts with others, communicates, and possibly even where the character is from and/or their educational level.
The teacher explains the purpose of the lesson, which is to read and study the story “Black Cowboy, Wild Horses”and identify the main character's qualities of self-discipline as well as their own traits of self-discipline. Self-discipline is making responsible choices in what I say and do to reach my personal goals.
hope this helps
I think it means that they were ready to prove it no matter what it took but not really sure since I haven’t read the whole story
