Answer:

High reliability and low validity

Explanation:

It was stated that the children took the test twice and had similar scores, hence the test has high reliability because it produces the same or similar results under the same conditions. Validity is tested to see how the results of the study really measured what they were intended to, checking how the results is in line with concepts and theories, and if the results are reproducible.

Jobisdone [24]

Answer:

They attempted to keep their schools segregated.

Explanation:

The Brown v. Board of Education of Topeka was a landmark litigation or court case between Oliver Brown and the Board of Education in which the justices of the Supreme Court unanimously ruled (9-0) in 1954 that racially segregating children in public schools was unconstitutional because it violates the Equal Protection Clause of the Fourteenth Amendment (14th) of the Constitution of the United States of America.

Meanwhile, on the 4th of September, 1957, the first day of resumption of class activities at Central High School, the Governor of Arkansas, Orval Eugene Faubus invited the Arkansas National Guard to block all African-Americans (black) students from entering into the school.

Hence, the states with segregated school systems responded to the Supreme Court ruling in Brown v. Board of Education by attempting to keep their schools segregated.

How did Battle of Tippecanoe contribute to the War of 1812?
hram777 [196]
Upon arriving at the site, Harrison<span> warned his men of the possible treachery of the </span>Prophet<span>. The troops were placed in a quadrangular formation; each man was to sleep fully clothed. Fires were lit to combat the cold, rainy night, and a large detail was assigned to sentinel the outposts. Although </span>Tecumseh<span> had warned his brother not to attack the white men until the confederation was strong and completely unified, the incensed Prophet lashed his men with fiery oratory. Claiming the white man's bullets could not harm them, the Prophet led his men near the army campsite. From a high rock ledge west of the camp, he gave an order to attack just before daybreak on the following day. The sentinels were ready, and the first gunshot was fired when the yells of the warriors were heard. Many of the men awoke to find the Indians upon them. Although only a handful of the soldiers had had previous battle experience, the army bloodily fought off the reckless, determined Indian attack. Two hours later, thirty-seven soldiers were dead, twenty-five others were to die of injuries, and over 126 were wounded. The Indian casualties were unknown, but their spirit was crushed. Angered by his deceit, the weary warriors stripped the Prophet of his power and threatened to kill him. Harrison, expecting Tecumseh to return with a large band of Indians, fortified his camp soon after the battle. No man was permitted to sleep the following night. Taking care of their dead and wounded, the demoralized Indians left Prophet's Town, abandoning most of their food and belongings. When Harrison's men arrived at the village on November 8, they found only an aged squaw, whom they left with a wounded chief found not far from the battlefield. After burning the town, the army began their painful return to Vincennes.</span>
