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"

A nation's competitiveness resides not only in their abundance in natural resources but in the quality of its human capital. If a nation lacks the natural resources that are sought for in the world, it can compensate that by focusing on giving its citizens the best education possible in order for them to become skilled workers in the future. This will enable them to with the capacity to generate new knowledge and develop innovating industries which are profitable. The products that these industries produce normally fall in the categories of electronics, software, the automotive industry, and the aviation industry. The country will import the raw material and produce highly specialized products that it will end up selling to those same countries that sold them the raw material.
A clear example of this is Japan. The country lacks the natural resources that other countries have like oil and minerals. However, the Japanese industry is responsible for the creation of many electronics that we use nowadays. This has produced the country incredible wealth over the last 50 years.
