Answer:
The author writes with great scientific detail.
Explanation:
Simon Singh's "The Code Book" presents a detailed account of the history of cryptography through the tracing of its evolution and how secrecy came to be. The idea of a secret code for messages is what intrigues everyone and thus, this book delves into the how of such coded messages.
As seen in the given excerpt, the author Simon Singh states how scientific details such as <em>"p and q"</em> and the factoring of <em>"the public key, N"</em> are all processes to learn about Alice's private key. The inclusion of details such as <em>"check[ing] each prime number one at a time to see if it divides into N"</em> are all scientific approaches that will lead to the understanding of the private key.
Thus, the correct answer is the last or fourth option.
Answer and Explanation:
Since your question does not present any options to choose from, I'll answer based on my knowledge of the story.
<u>In the short story "To Build a Fire", by Jack London, the immediate danger that concerns the man is freezing to death.</u> The character of the story has ignored a warning an old man gave him about roaming in the forest by himself when the cold weather is harsh. He chose to trust his abilities against nature, only to be humbled by it. The man did not have the knowledge, wisdom, and capacity to survive in the wild. The freezing temperatures were going to kill him if he didn't build a fire to keep himself warm. Even the dog that accompanies the man knew that, and couldn't seem to understand why the man wouldn't do it. However, when the man finally realized the urgent need for fire, he was not able to start one, and ended up dying. That is indeed a common theme in Jack London's work - the survival of the fittest. Had the man been smarter or stronger, he would have survived.
That would be C, a prepositional phrase.
