Namely, most human language feature four skills, divided into productive skills and receptive skills.
- Productive skills: speaking and writing.
- Receptive skills: listening and reading.
For a long time, human languages only featured one productive skill, speaking, and one receptive skill, listening. Writing and reading would appear at a later time within the ancient cultures of Mesopotamia (who invented the cuneiform writing system) and ancient Egypt (who developed hieroglyphic and demotic writing systems). Even today, many human groups living in isolated and remote areas have not developed writing and reading, relying solely on speaking and listening and on oral tradition (passing down the history of the group from one generation to the next) for their communication needs.
Answer:
Explanation:
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 and evolve.
As with any author's decision to use 1st person, her intention most likely -- in this story -- was to get her readers to go along for the ride into madness and cultivate a certain amount of sympathy for the narrator and her plight. The constant use of "I" puts readers in the narrator’s head and allows them to empathize with her.
