i can persuade myself why c is the correct answer after i checked answer key, but just have some problem eliminating E, which i original chose.
especially since the author mentioned in the second paragraph that although the theory became "gradually accepted", but some scientists still remained "skeptical", until "recently" new evidence has been gathered and thus provide explanation. Thus the wording "presentation of new information that challenges the theory; modification of the theory to accommodate the new information" seem to totally match. Then why is E incorrect?
Thanks for help!
