Answer:
A. Humans first lived in East Africa.
B. Migration occurred by land and sea
D. Humans crossed a land bridge to North America.
Explanation:
Human migration is defined as the movement of humans from one place to another.
The earliest humans lived in East Africa about 3 million years ago and the earliest humans are known as Homo habilis. Richard Leakey found the first human species in the 1960s at Omo Kibish in south-western Ethiopia.
Migration occurred by land and sea in the earlier time. Humans used land bridges to move from one place to another and whenever sea level goes down they migrate through sea or water sources as well.
During the last ice age, humans crossed a land bridge to North America from Asia about 20,000 years ago. The land bridge is submerged underwater due to rise in sea levels.
Hence, the correct answers are "A, B, and D"
Answer:
c
Explanation:
Following the defeat of Germany and Ottoman Turkey in World War I, their Asian and African possessions, which were judged not yet ready to govern themselves, were distributed among the victorious Allied powers under the authority of Article 22 of the Covenant of the League of Nations (itself an Allied creation). The mandate system was a compromise between the Allies’ wish to retain the former German and Turkish colonies and their pre-Armistice declaration (November 5, 1918) that annexation of territory was not their aim in the war. The mandates were divided into three groups on the basis of their location and their level of political and economic development and were then assigned to individual Allied victors (mandatory powers, or mandatories).
Class A mandates consisted of the former Turkish provinces of Iraq, Syria, Lebanon, and Palestine. These territories were considered sufficiently advanced that their provisional independence was recognized, though they were still subject to Allied administrative control until they were fully able to stand alone. Iraq and Palestine (including modern Jordan and Israel) were assigned to Great Britain, while Turkish-ruled Syria and Lebanon went to France. All Class A mandates reached full independence by 1949.

he Italian city-states were a political phenomenon of small independent states mostly in the central and northern Italian peninsula between the 9th and 15th centuries.
After the fall of the Western Roman Empire, urban settlements in Italy generally enjoyed a greater continuity than in the rest of western Europe. Many of these towns were survivors of earlier Etruscan, Umbrian and Roman towns which had existed within the Roman Empire. The republican institutions of Rome had also survived. Some feudal lords existed with a servile labour force and huge tracts of land, but by the 11th century, many cities, including Venice, Milan, Florence, Genoa, Pisa, Lucca, Cremona, Siena, Perugia, Spoleto, Todi, Terni, and many others, had become large trading metropoles, able to obtain independence from their formal sovereigns.
