Which statement about slavery in America in the 1780s is true?

The correct answer is Many southern states prohibited the importation of slaves from abroad

Black slavery was implanted during the 17th century and intensified between the years 1700 and 1822, mainly due to the great growth of the slave trade. The height of the influx of black slaves can be found between 1701 and 1810, when 1,891,400 Africans were landed in colonial ports.

The history of slavery (or slavery) in the United States begins in the 17th century, when slave practices similar to those used by the Spanish and Portuguese in colonies in Latin America. The year 1820, for example, is important because on March 2 a compromise was signed that would temporarily calm the differences on the issue of slavery. As a result of this commitment, a new anti-slavery state is inaugurated. Maine would result from the separation of Massachusetts and sought a counterpoint to Missouri. Moreover, it was agreed that the future states that were created in old Louisiânia would be slavery or abolitionists according to their location to the south or north of the parallel 36 ° 30 ', southern border of Missouri. This compromise eases tensions for three decades. However, the divergences in economic and political interests between the North and the South end up making them resurface more alive than ever. In fact, slavery ended only in 1863, with the Abraham Lincoln Emancipation Proclamation, carried out during the American Civil War.

the children of nome were dying in january 1925. infected with diphtheria, they wheezed and gasped for air, and every day brought a new case of the lethal respiratory disease. nome’s lone physician, dr. curtis welch, feared an epidemic that could put the entire village of 1,400 at risk. he ordered a quarantine but knew that only an antitoxin serum could ward off the fast-spreading disease.the nearest batch of the life-saving medicine, however, rested more than 1,000 miles away in anchorage. nome’s ice-choked harbor made sea transport impossible, and open-cockpit airplanes could not fly in alaska’s subzero temperatures. with the nearest train station nearly 700 miles away in nenana, canine power offered nome its best hope for a speedy delivery.sled dogs regularly beat alaska’s snowy trails to deliver mail, and the territory’s governor, scott c. bone, recruited the best drivers and dog teams to stage a round-the-clock relay to transport the serum from nenana to nome. on the night of january 27, 1925, a train whistle pierced nenana’s stillness as it arrived with the precious cargo—a 20-pound package of serum wrapped in protective fur. musher “wild bill” shannon tied the parcel to his sled. as he gave the signal, the paws of shannon’s nine malamutes pounded the snow-packed trail on the first steps of a 674-mile “great race of mercy” through rugged wilderness, across frozen waterways and over treeless tundra.even by alaskan standards, this winter night packed extra bite, with temperatures plummeting to 60 degrees below zero fahrenheit. although every second was precious as the number of confirmed cases in nome mounted, shannon knew he needed to control his speed. if his dogs ran too fast and breathed too deeply in such frigid conditions, they could frost their lungs and die of exposure. although shannon ran next to the sled to raise his own body temperature, he still developed hypothermia and frostbite on the 52-mile leg to tolovana before handing off the serum to the second dog team.
