Paleontologists have made an exciting find on the coast of the Baltic

The following excerpt from a fictitious popular science journal discusses the discovery of fossil remains of a fictitious animal genus called Edruciraptor.

Paleontologists have made an exciting find on the coast of the Baltic Sea. A nearly complete skeleton of what appears to be a previously unknown miniature theropod dinosaur has been excavated and subjected to rigorous analysis. Like other theropods, the newly discovered genus, for which the name Edruciraptor has been proposed, was bipedal and lacked the ability to pronate its forelimbs. Like the dromaeosaur, Edruciraptor displayed highly inflexible fingers but good wrist mobility. However, while the dromaeosaur walked on only two of its three hind toes, reserving the third for brandishing an imposing curved claw (essential for tree climbing), Edruciraptor walked on all three toes and lacked the characteristic dromaeosaur sickle claw. The limited fossil evidence also indicates that Edruciraptor had feathers, a rapid gait (all small theropod dinosaurs could run), and possibly an omnivorous diet.

Based on what can be inferred about Edruciraptor as described in the previous paragraph, which of the following must be a characteristic of this fictitious dinosaur, and which cannot be a characteristic? Make only two selections, one in each column.

Must be a characteristic of Edruciraptor	Cannot be a characteristic of Edruciraptor
		Tree climbing
		Omnivorous diet
		Ability to fly
		Ability to run
		Ability to swim
		Shoulder flexibility
