The writer is working on a new version of the passage and wants to include an explicit statement of the passage's thesis.
Which of the following would best serve as a thesis statement for the passage?
?
A
Recent research has revealed that Nemesis, a twin star to our Sun, has the ability to create astronomical events that affect the planets in our solar system
o
B)
It is unlikely that scientists will ever be able to identify why major extinction events seem to occur every 26 million years.
с
While the theory was initially promising, the existence of Nemesis (a supposed companion star to the Sun) and its effect on extinction events on Earth, is highly
doubtful.
D
Advances in technology greatly assist scientists in their work to prove the validity of theories posited by earlier researchers
E
Debris disks are always affected by companion stars, so researchers should focus on identifying the companion star linked to the Oort cloud in order to further
research on why extinction events occur every 26 million years.
