Scientists wishing to understand the kinetic movements of ancient dinosaurs are today studying the movements of modern day birds, which many scientists believe are descended from dinosaurs. A flaw in this strategy is that birds, although once genetically linked to dinosaurs, have evolved so far that any comparison is effectively meaningless
Which of the following, if true, would most weaken the criticism made above of the scientists’ strategy?
(A) Birds and dinosaurs have a number of important features in common that exist in no other living species.
(B) Birds are separated from dinosaurs by 65 million years of evolution.
(C) Our theories of dinosaur movements have recently undergone a radical reappraisal.
(D) The study of kinetic movement is a relatively new discipline.
(E) Many bird experts do not study dinosaurs to draw inferences about birds

(A) Birds and dinosaurs have a number of important features in common that exist in no other living species.
Correct answer choice since this choice provides strong link between the birds and the Dinosaurs and also mention that there is no other species related to dinosaurs more than birds.
(B) Birds are separated from dinosaurs by 65 million years of evolution.
weakens the purpose of study and therefore it is strengthening the criticism.
(C) Our theories of dinosaur movements have recently undergone a radical reappraisal.
does not weaken the argument.
(D) The study of kinetic movement is a relatively new discipline.
Out Of Scope
(E) Many bird experts do not study dinosaurs to draw inferences about birds
The study is focused on birds and dinosaurs to find movements in dinosaur and not the movement in birds
