I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "The exact relationship between these eight groups is not yet clear, although there is agreement that the first three groups to diverge from the ancestral angiosperm were Amborellales, Nymphaeales, and Austrobaileyales. The term basal angiosperms refers to these three groups. Among the rest, the relationship between the three broadest of these groups (magnoliids, monocots, and eudicots) remains unclear. Some analyses make the magnoliids the first to diverge, others the monocots. Ceratophyllum seems to group with the eudicots rather than with the monocots."? 

What is another way to refer to Amborellales, Nymphaeales, and Austroaileyales as a whole?
