Answer:
" this premeditated invasion "
" our interests are in grave danger "
Explanation:
The author seems to want to make the reader step back and ponder, maybe a bit out of fear as much as anything else. And he does so by using loaded words like " grave " Invasion " " premeditated " ect. ect.
I want to say either diaries or fashion magazines. Diaries are much more story like and could be a little lathered up for lack of a better word. However I would go with fashion magazines, which talk about whatever's popular at the time, giving you a quick general outlook on the time period.
Is this supposed to be a story ?
