In what did both the mayans and the egyptians show an interest?
a) print-making
b) chemistry
c) poetry
d) astronomy
if anyone can me with this one and if you can a couple other ones it would mean alot

The answer is D because in Egypt the pyramids line up at the constellations and the Mayas taught astronomy to children.

explanation:

the addition to geographic boundaries that might have  kept the people of the huang river civilization from traveling to far distance region is that they had learned about the other river valley civilizations but feared contact would bring invasion.

hope this .
