Problem: Please answer a question about the following article about Eritrea:
In 2010, a genetic study was conducted on the mummified remains of baboons that were brought back as gifts from Punt by the ancient Egyptians. Led by a research team from the Egyptian Museum and the University of California, the scientists used oxygen isotope analysis to examine hairs from two baboon mummies that had been preserved in the British Museum. One of the baboons had distorted isotopic data, so the other's oxygen isotope values were compared to those of present-day baboon specimens from regions of interest. The researchers found that the mummies most closely matched modern baboon specimens in Eritrea and Ethiopia, which they suggested implied that Punt was likely a narrow region that included eastern Ethiopia and all of Eritrea.
Who was determined to be the closest match for the baboon mummies?
A: modern baboon specimens in Eritrea and Ethiopia
Problem: Please answer a question about the following article about Alfred North Whitehead:
In fact, Whitehead describes any entity as in some sense nothing more and nothing less than the sum of its relations to other entities – its synthesis of and reaction to the world around it. A real thing is just that which forces the rest of the universe to in some way conform to it; that is to say, if theoretically a thing made strictly no difference to any other entity (i.e. it was not related to any other entity), it could not be said to really exist. Relations are not secondary to what a thing is, they are what the thing is.
If relations are not secondary to what a thing is, what is it?
A: they are what the thing is
Problem: Please answer a question about the following article about Sahara:
The effects of local surface low pressure are extremely limited because upper-level subsidence still continues to block any form of air ascent. Also, to be protected against rain-bearing weather systems by the atmospheric circulation itself, the desert is made even drier by his geographical configuration and location. Indeed, the extreme aridity of the Sahara can't be only explained by the subtropical high pressure. The Atlas Mountains, found in Algeria, Morocco and Tunisia also help to enhance the aridity of the northern part of the desert. These major mountain ranges act as a barrier causing a strong rain shadow effect on the leeward side by dropping much of the humidity brought by atmospheric disturbances along the polar front which affects the surrounding Mediterranean climates.
What is blocked due to local surface low pressure?
A: air ascent
Problem: Please answer a question about the following article about Bird migration:
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?
A:
a few days
