To enforce referential integrity, the database can return an error instead of doing the requested action or do the requested action and do the related changes to the related tables
Thus the answer is either a or b.
Explanation:
When the given data base in a table is valid and if it is consistent then it is called as referential integrity and it also refers to the consistency within the relationship. This type of database is much important because it will keep us introducing to the errors in the databases and it also checks if the reference from one table is equal to the other table.
The main function is to prevent the users from entering the wrong and inconsistent data. So in referential integrity the database will return the error instead of doing the required action or it can do the related changes to the related tables.
The correct answer is B. The Court outlawed de jure segregation.
Explanation:
Brown v. Board of Education was a legal case in 1954, in this, Oliver Brown and other African American parents sued the Board of Education for the segregation in schools as African-American children had to attend school at a different building than other children. This situation was common by then and it was part of the de jure segregation or the segregation supported by law as before the Brown v. Board of Education case segregation was allow if the services provided were equal. However, with the Brwon v. Board of Education, the Supreme Court established this segregation was unconstitutional and therefore it outlawed de jure segregation.

<span>From outsiders perspective - not very different from disadvantages elsewhere, but bigger.
I see two, just from general paying attention to news.
1) resources extracted by colonists (maybe less so now, but still) and so not available to the natives of the reason, going instead to China or whoever is doing the extracting now.
2) Tough, dirty, dangerous job to do the actual mining. Tough - wears down the miners. Dirty - will cause long term damage, like black lung. Dangerous - both mining accidents and possible danger from dealing with the greedy.
So, to summarize, the risks are publicized to the regional people, the rewards are privatized to whoever has the power.</span><span>
