Osmosis is the net movement of water molecules through a semi-permeable memberane from a region of higher water potential to a region of lower water potential.
so in the first case, since 10% of sucrose solution has a lower water potential than the pure water, so water molecules will flow into the sac, causing the sac to increase in volume. note that sucrose molecules can't diffuse out since there's a semi-permeable membrane.
in the question, I'm not 100% sure what the "sac solution" is meant by, but I guess it's the solution inside the sac
so here if the sac sucrose is 20%, the concentration of water is larger in difference than the first time, so osmosis rate will increase.
but if the "sac solution" is meant by replacing the water of the first case, then the sac inside would have a higher water potential, as the sucrose concentration is more diluted. then the water molecules will flow from the sac back to the beaker or whatever container it is.

Explanation:
Between about 800 and 1200 AD, partly in response to the new currents of trade, Africans in the southern sahel developed a set of trading states with an elaborate organization.Well before 1500 AD, a number of states had come into existence, that had no connection at all with the trade across the Sahara.

The correct answer is A) The Inca had a public education system under the oversight of a government authority.
The political policies of the Inca Empire were similar to the sultan’s policies in India, as described in the passage in that "the Inca had a public education system under the oversight of a government authority."
For the Inca people, education was a priority. And teh Inca emperor ordered to have a good education system in the empire. Although in the empire there were social classes, education was for all divided into two: the education designed for the upper classes and the education designed for the Inca people in general. The teachers that shared knowledge to the upper classes were known as the Amawtakuna; they were wise men that taught the high classes. Education in the other social classes was transmitted from parents to children.
