Should We Bring Back Extinct Species?
Section #1
The idea of bringing extinct species back to life is known as “de-extinction,” and it’s now a legitimate scientific field. By extracting DNA from museum specimens and splicing it into the cells of similar living species, scientists say they can engineer animals back into existence. Researchers have started thinking seriously about which extinct species to focus their efforts on. Near the top of most lists are the woolly mammoth, which lived in the Arctic and went extinct about 4,000 years ago, and the passenger pigeon, which was once the most common bird in North America but went extinct in 1914.
But just because scientists may be able to bring species back doesn’t mean they should. Two scientists debate the ethics of de-extinction.

Question 3
3. Examine the author's word choice at the end of section #1. Which position does the author seem to show bias toward? In other words, which position does the author seem to agree with?(1 point)
Responses
We should bring back extinct species.
We should bring back extinct species.
We should not bring back extinct species.
To answer these questions, let's analyze the passage in Section #1:
1. The author does not directly define the term "de-extinction" but provides context clues to help readers infer its meaning. By explaining that de-extinction involves extracting DNA from extinct species and engineering them back into existence, the author allows readers to understand that de-extinction refers to the process of bringing extinct species back to life. Therefore, the context clue strategy used here is "explanation/example."
2. The central idea of Section #1 is that scientists are now capable of engineering extinct animals back into existence by extracting DNA from museum specimens and splicing it into similar living species. So, the correct answer is "Scientists are able to engineer extinct animals back into existence."
3. To determine the author's bias, we need to analyze the passage's tone and word choice. In this case, the author does not explicitly state their opinion but presents two viewpoints on the ethics of de-extinction. Without a clear bias towards either position, we cannot determine which one the author agrees with. Therefore, neither "We should bring back extinct species" nor "We should not bring back extinct species" accurately reflects the author's bias.
