Does regents of the university of california v. bakke remain relevant or has it been superseded by another case?

It has been suppressed by Grutter v. Bollinger (2003).

Explanation:

According to the University of California v. Bakke case (1978), college applicants’ race was allowed to be a factor in the admission policy, though racial quotas were ruled as impermissible.

Meanwhile, in 2003 Grutter v. Bollinger case ended with a court's decision that admission policy that favors poorly represented ethnic minority groups does not violate the Fourteenth Amendment's Equal Protection Clause, only if the policy takes other factors, such as academic excellence, into account.

Firearms and gunpowder.

Explanation:

After this period Tokugawa Shogunate had begun and Oda Nobunaga was first to use those kinds of technologies. He ordered 500 matchlocks and gave them to his army. They were used successfully.
