[mm5566t (Easonchen)]

Many explanations have been proposed for why dinosaurs became extinct. For exa
mple, some have blamed dinosaur extinction on the development of flowering pla
nts, which were supposedly more difficult to digest and could have cost consti
pation or indigestion--- except that flowering plants first evolved in the Ear
ly Cretaceous, about 60 million years before the dinosaurs died out. In fact,
several scientists have suggested that the duckbill dinosaurs and homed dinosa
urs, with their complex battery of grinding teeth, evolved to exploit this new
 resources of rapidly growing flowering plants.

 plants evolved?

A To help explain why some scientists believe that the development of the plan
ts led to dinosaur extinction

B To cast doubt on the theory that the development of flowering plants caused
 dinosaurs to become exti nct
