We can actually deduce here that the astronaut that raised his hand actually said that the colour of the feather placed on his helmet was blue and going further to give a logical explanation, he explained that this is because the sky of the planet where they are is blue.
<h3>What is logical explanation?</h3>
Logical explanation actually refers to the explanation that is given using logic and what everyone sees and knows. In logical reasoning, one speaks based on what he/she knows or acquires from reasoning or thinking through.
We see here that logically thinking, the helmet placed on their heads actually denoted sky and the blue feather denotes the colour of the sky. Remember they were told not to look up. That means what we are looking for is up which is the sky.
Thus, we can say here that the colour of the feather placed on his helmet is blue and it actually talks about the colour of their planet.

1: Read the introductory info if there is one.
2: Watch out of the words that the author chose.
I want to inform you that the summary on Peace like a River will not be short. Here is the paragraph I managed to find. One part Christian-inflected odyssey, one part tragedy, and one part classic adventure in the American West, Peace Like a River by Leif Enger is the story of a 1960s Minnesota family narrated by the asthmatic Reuben, the product of the first of his father’s seven miracles. The title takes its name from the Christian hymn “It Is Well With My Soul” In case, you feel like this is not enough, I want you to check what the writers from Prime Writings can do for you.
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.
