Can you maybe provide more detail?
Answer:
E). During the period immediately before the asteroid that produced the Chicxulub crater struck, most of the world’s dinosaurs lived in or near the region of the asteroid’s impending impact.
Explanation:
As per the question, option E displays the statement that would most likely weaken the argument, if true as it functions to deny the author's claim that 'when the asteroid(around six miles ago) struck the Earth, the last dinosaur species were becoming extinct' by presenting contradictory statement 'most of the world’s dinosaurs lived in or near the region of the asteroid’s impending impact.' Thus, this statement(if true) would not only weaken the argument but also influence the author's credibility and character among the audience. Thus, <u>option E</u> is the correct answer.
