Nigeria developed trade in iron, much like ancient meroe in east africa. which of these problems that destroyed the kushivte civilization might have affected the nigerians?

a: deforestation due to the need to burn wood to smelt the ore
b: reduction of water in rivers due to sluicing and damming
c: pollution of the ocean due to rusting of agricultural tools
d: reduction of prey due to hunting with advanced weapons

There are several reasons that also led to the fall of ancient Meroe however, from the options presented :

A - deforestation due to the need to burn wood to smelt the ore.

Explanation:

The thriving Kush civilization south of Egypt and north of Sudan, had its administrative centre in Meroe in about 500 BCE, this region blessed by its geographical location permitted the extraction of iron ore. The smelting of iron led to the development of iron technology in Meroe which in turn helped to maintained the trans Saharan commercial trades within several regions in Africa including Egypt and across the Red Sea to Greece and Rome.

About this same period of 500 BCE, the Nok culture existed  in a region occupied by modern day Nigeria.  This culture of an early Iron Age population, was probably the first known civilization in the West African region to perfect iron smelting and produce of terracotta art sculptures.

Both civilizations suffered from the decline in their economic activities as the iron smelting was used in the production of tools for agriculture, hunting, art, and further land occupation. This exerted much pressure on the environment, leading to deforestation of geographical areas for obtaining charcoal from trees used in the smelting of iron.

a countries leader should be motivated by the common good of the country.

i'll tell you everything i know

explanation:

the american entry into world war i came in april 1917, after more than two and a half years of efforts by president woodrow wilson to keep the united states out of the war.

apart from an anglophile element urging early support for the british, american public opinion reflected that of the president: the sentiment for neutrality was particularly strong among irish americans, german americans, and scandinavian americans, as well as among church leaders and among women in general. on the other hand, even before world war i had broken out, american opinion had been more negative toward germany than toward any other country in europe. over time, especially after reports of atrocities in belgium in 1914 and following the sinking of the passenger liner rms lusitania in 1915, american citizens increasingly came to see germany as the aggressor in europe.

wilson, as president, made virtually all the key decisions over foreign policy. while the country was at peace american banks made huge loans to britain and france, which were used mainly to buy munitions, raw materials, and food from across the atlantic. until 1917, wilson made minimal preparations for a land war and kept the united states army on a small peacetime footing, despite increasing demands for enhanced preparedness. he did, however, expand the united states navy.

in 1917, with russia experiencing political upheaval, and with britain and france low on credit, germany appeared to have the upper hand in europe, while the ottoman empire, germany's ally, held on to its territory in modern-day iraq, syria and israel. at this point germany decided to resume unrestricted submarine warfare. its goal was to starve britain into surrender, although it realized that this would almost certainly bring the united states into the war. germany also made a secret offer to mexico regain territories lost in the mexican–american war in an encoded telegram known as the zimmerman telegram, which was intercepted by british intelligence. publication of that communique outraged americans just as german u-boats started sinking american merchant ships in the north atlantic. wilson then asked congress for "a war to end all wars" that would "make the world safe for democracy", and congress voted to declare war on germany on april 6, 1917.

on december 7, 1917, the u.s. declared war on austria-hungary.

u.s. troops began arriving on the western front in large numbers in 1918.
