1. What did the ortaq system do for traders?
A. It employed a Mongol to hunt down enemy traders and seize their goods.
B. It took trade away from non-Mongols by keeping trade entirely within the Mongol Empire.
C. It was a tax merchants had to pay to trade in Mongol territory.
D. It placed them in a partnership with a Mongol that granted them protection and other accommodations.
2. Analyze the correlation between Roman expansion policy and trade in the Indian Ocean.
A. There was no correlation between Roman expansion and trade, as they occurred for separate reasons.
B. The Romans conquered any civilization would not trade with them as a means of punishment.
C. As the Romans conquered territory, they gained access to trade resources, which encouraged more expansion.
D. The Romans expanded to protect their trade interests and spread their religion.
3. Analyze what the Black Death was and its impact.
A. It was the name of a Mongol who killed lots of people.
B. It was a plague that travelled along the Silk Road and devastated communities and economies
C. It was the name given to black pearls found at the bottom of the Indian Ocean and which civilizations fought over.
D. It was a poison transported between people in the Indian Ocean.
4. Which statement best analyzes the impact of Indian Ocean trade on religious beliefs in Africa?
A. Arab merchants settling on the Swahili coast influenced cultural diffusion, leading to larger Muslim populations in eastern Africa
B. Buddhism became the major religion of East Africa after merchants from southeast Asia settled there to be a part of Indian Ocean trade.
C. Indian merchants formed settlements in North Africa, spreading Hindu customs.
D. Inspired by the voyages of Zheng He, Chinese merchants settled in Africa and spread Confucianism, leading to large pockets of Confucian populations there.
5. Which statement best explains why the Silk Road trade network developed
A. Political stability led to an increased demand for goods in the Roman and Chinese empires
B. Favorable monsoon winds made trade between China and Rome easier.
C. Berber traders responded to a demand for gold in the Byzantine Empire.
D. The two regions had a positive relationship which motivated them to trade.
1. D. It placed them in a partnership with a Mongol that granted them protection and other accommodations.
2. C. As the Romans conquered territory, they gained access to trade resources, which encouraged more expansion.
3. B. It was a plague that travelled along the Silk Road and devastated communities and economies.
4. A. Arab merchants settling on the Swahili coast influenced cultural diffusion, leading to larger Muslim populations in eastern Africa.
5. A. Political stability led to an increased demand for goods in the Roman and Chinese empires.
1. The correct answer is B. Lysosomes break down worn-out cell parts that are no longer needed. They contain enzymes that help break down molecules and cellular waste materials, allowing the cell to recycle components and maintain its health.
2. The correct answer is C. The cell wall provides structure and rigidity to a plant cell. It is a rigid outer layer made of cellulose that surrounds the cell membrane and provides support, protection, and shape to the cell.
3. The correct answer is D. If the chloroplasts in a plant cell become damaged, the plant would not be able to carry out photosynthesis effectively. As a result, it would not be able to produce glucose and oxygen, which are essential for the plant's survival.
4. The correct answer is A. Plant root cells lack chloroplasts because they are usually underground and receive limited exposure to sunlight. Chloroplasts are responsible for photosynthesis, which requires light energy. Since roots are not positioned to receive sufficient sunlight, they do not have a significant need for chloroplasts.
5. The correct answer is A. The main difference between prokaryotic and eukaryotic cells is that prokaryotes lack membrane-bound organelles. Prokaryotic cells, such as bacteria, do not have a nucleus or other membrane-bound organelles, while eukaryotic cells, found in plants, animals, and fungi, have a nucleus and various membrane-bound organelles, such as mitochondria, endoplasmic reticulum, and Golgi apparatus.
