In sentence 10 (reproduced below), the writer is considering deleting the underlined parenthetical text.
And while the Sun may well have had a twin at some point (a 2017 study of the Perseus molecular cloud suggests that most stars like the Sun were formed with companions),most experts now agree that if Nemesis ever existed, it broke free of the solar system early in the Sun's history, long before there was life on Earth, and thus could not have figured in any extinctions.
Should the writer keep or delete this text?

Respuesta :

Despite the possibility that the Sun once had a twin (a 2017 study of the Perseus molecular cloud suggests that most stars like the Sun were formed with companions), the majority of scientists now concur that Nemesis, if it ever existed, broke free of the solar system very early in the Sun's history, long before there was life on Earth.

Should the author leave this text alone or delete it?

Keep it in place since it sets up the discussion of the two studies that are cited at the passage's end in parenthetical text.

Keep it because it indicates a potential route for further investigation of stars outside the Sun. Keep it in the sentence because it directly supports the concession made earlier in the paragraph. Delete it because it introduces unrelated material, which disrupts the flow of the argument.
