Answer: variable
Explanation:
Any factor with more than one value
Indigenous<span> cultures shaped, and were shaped by, the </span>geography<span> of North America. The first North Americans are believed to have </span>migrate<span>d from Siberia, in northeast Asia, by crossing a </span>land bridge<span> over the Bering Strait. These populations fanned out southward, to present-day Florida, California, Mexico, and Central America. </span>
<span>The Olmec and the Maya, indigenous to Central America, built the first cities on the continent, eventually leading to the great urban areas of Tenochtitlan, Texcoco, and Tlacopan. These cities, in what is now central Mexico, boasted </span>sophisticated engineering<span> structures, such as </span>canal<span>s, apartment buildings, and </span>irrigation<span> systems. </span>
<span>Many of these early North American cultures were scientifically and agriculturally advanced. Mayan calendars and </span>almanac<span>s recorded </span>celestial<span>events such as </span>eclipse<span>s and </span>seasonal<span> changes. The Mayans were also mathematically advanced. Their counting system was able to represent very large numbers using only three symbols: dots, lines, and a football-shaped symbol that indicated a zero. The Mayans were, in fact, the first culture to have a written symbol for zero. </span>
<span>Cultures throughout southern North America harvested corn, squash, and beans in regular cycles. This sort of </span>agriculture<span> allowed major </span>civilization<span>s to develop. People were no longer bound to produce food and shelter for their families—some people could work in the food and construction industries while others became engineers, artists, and political leaders. Leading North American civilizations include the Maya and Aztec, in what is now Mexico, and the Iroquois, native to southeastern Canada and the northeastern United States. .................</span>
<span>Deregulation and Tax cuts or Tax rebates are the two ways where an economy stabilized with the production point. Deregulation is the relaxing of rules and regulations imposed on an industry or business. Tax cuts and tax rebates are designed to put more money back into the pockets of consumers. Ideally, these consumers spend a portion of that money at various businesses, which increases the businesses' revenues, production, cash flows and profits.</span>
The correct answer is The lack of a seaport to trade goods might put the people at an economic disadvantage
Landlocked, inland or inland countries
Thus are known in the 'concert of nations' the 44 countries that have no outlet to the sea. In common, besides geography, poverty, the difficulty of doing trade, expanding its presence in the world, winning markets, etc. In Europe, only five of these countries have managed to get rid of poverty, but three of them have had to take serious risks in their banking systems so that, like the oceans, they attract wealth. We speak of Switzerland, Liechtenstein and Luxembourg. The other two European countries are Austria and San Marino. Africa contributes 16 more; Asia, ten; and South America, two more, Bolivia and Paraguay.
