Answer:
A. Knowing that the attack might reach us in all too short a time, we
immediately began greatly to increase our industrial strength and
our capacity to meet the demands of modern warfare.
Explanation:
The attack is coming quickly so the logical thing to do is to prepare. The other examples are motivational or pathological statements while the first one (A) uses a clear and methodical string of thought to find a solution for the coming attack.
(If a picture type thing helps you: attack coming soon---what do we do?---begin to prepare for the attack immediately.)
Haven't read the book but this may be helpful to you:
"<span>In The History of the Kings of Britain, Geoffrey of Monmouth proposes to set forth the history of the British kings starting with Brutus and ending with Cadwallo. Geoffrey undertakes this endeavor at the request of the Archdeacon of Oxford who presents Geoffry with an ancient text to translate from British into Latin. The history of the British kings shows how fortune, jealousy, and betrayal can lead to the demise of an entire nation. On the other hand the text also details the qualities that are necessary in a good ruler who unites his people in peace. While Geoffrey's account reads like a novel, the basis for the book is historical and gives the reader a generalized view of British history."
