PrepTest 74, Section 3, Question 10
In 2005, paleontologist Mary Schweitzer made headlines when she reported finding preserved soft tissue in the bones of a Tyrannosaurus rex dinosaur. Analysis of the collagen proteins from the T. rex showed them to be similar to the collagen proteins in modern-day chickens. Schweitzer's discovery therefore adds to the mountain of evidence that dinosaurs are closely related to birds.

The answer to which one of the following questions would be most useful to know in order to evaluate the argument?
How rare is it to find preserved soft tissue in the bones of a dinosaur?
Is there any evidence at all against the claim that dinosaurs are closely related to birds?
How likely is it for animals that are not closely related to each other to have similar collagen proteins?
Is it possible that T. rex is more closely related to modern-day chickens than to certain other types of dinosaurs?
Before Schweitzer's discovery, did researchers suppose that the collagen proteins in T. rex and chickens might be similar?
