Answer:
B: The kitten's white fur had earned her the name Frosty the Snowman

An allusion is an expression that makes an indirect or passing reference to another work of art, literature, or historical event without explaining it. Here, the cat is named "Frosty the Snowman", which would be an allusion to the story of Frosty the Snowman.
The words <em>possibility</em>, <em>normalization</em> and <em>hope</em> affect the tone of paragraphs 1 and 2 of this passage by helping to create a tone of cautious or subdued optimism.
The correct answer is A.
Those words make the reader feel like there is a big chance that the North and South denuclearize the Korean Peninsula, but cautiously because it is a very serious matter for the whole world and it has been in discussion for a long time.
