Problem: Many of the smaller insectivorous birds including the warblers, hummingbirds and flycatchers migrate large distances, usually at night. They land in the morning and may feed for a few days before resuming their migration. The birds are referred to as passage migrants in the regions where they occur for short durations between the origin and destination.
How long do passage migrants stop and feed before resuming migration?

Answer: a few days

Problem: Linda Woodhead attempts to provide a common belief thread for Christians by noting that "Whatever else they might disagree about, Christians are at least united in believing that Jesus has a unique significance." Philosopher Michael Martin, in his book The Case Against Christianity, evaluated three historical Christian creeds (the Apostles' Creed, the Nicene Creed and the Athanasian Creed) to establish a set of basic assumptions which include belief in theism, the historicity of Jesus, the Incarnation, salvation through faith in Jesus, and Jesus as an ethical role model.
According to Nicene Creed, what can Christians be united in believing?

Answer: unanswerable

Problem: If Mammalia is considered as the crown group, its origin can be roughly dated as the first known appearance of animals more closely related to some extant mammals than to others. Ambondro is more closely related to monotremes than to therian mammals while Amphilestes and Amphitherium are more closely related to the therians; as fossils of all three genera are dated about 167 million years ago in the Middle Jurassic, this is a reasonable estimate for the appearance of the crown group. The earliest known synapsid satisfying Kemp's definitions is Tikitherium, dated 225 Ma, so the appearance of mammals in this broader sense can be given this Late Triassic date. In any case, the temporal range of the group extends to the present day.
Which two groups are closely related to therian mammals?
---
Answer:
Amphilestes and Amphitherium
