I want to know the answer to the following question:
The two subdivisions of what group include Palaeognathae and Neognathae?
All the background I'm provided with is that "All modern birds lie within the crown group Aves (alternately Neornithes), which has two subdivisions: the Palaeognathae, which includes the flightless ratites (such as the ostriches) and the weak-flying tinamous, and the extremely diverse Neognathae, containing all other birds.". Is that enough to answer the question?
Answer: yes
