Biology
1 answer:
cestrela7 [59]3 years ago
8 0

Answer: More than 99 percent of all organisms that have ever lived on Earth are extinct. As new species evolve to fit ever changing ecological niches, older species fade away. But the rate of extinction is far from constant. At least a handful of times in the last 500 million years, 75 to more than 90 percent of all species on Earth have disappeared in a geological blink of an eye in catastrophes we call mass extinctions.

Though mass extinctions are deadly events, they open up the planet for new forms of life to emerge. The most studied mass extinction, which marked the boundary between the Cretaceous and Paleogene periods about 66 million years ago, killed off the nonavian dinosaurs and made room for mammals and birds to rapidly diversify

In about 100 words, explain how the use of flashback adds meaning to “Rules of the Game.” Be sure to use details from the story
babymother [125]

Answer:

The use of flashback in "Rules of the Game" provides insight into the complicated relationship between Waverly and her mother. Throughout the story, Waverly describes past incidents when cultural differences caused her and her mother to view events differently. Waverly sees events differently because of her American upbringing. Her mother sees events differently because of her Chinese upbringing. Waverly notes that her mother has had difficulty adjusting to American culture. She shows this struggle when she describes her mother’s reaction to the game manual for her brother’s new chess set:

“This American rules,” she concluded at last. “Every time people come out from foreign country, must know rules. You not know, judge say, Too bad, go back. They not telling you why so you can use their way go forward. They say, Don’t know why, you find out yourself. But they knowing all the time. Better you take it, find out why yourself.” She tossed her head back with a satisfied smile.
