Title VII was perhaps the most controversial of the entire bill. Many conservatives accused it of advocating a de facto quota system, and claimed unconstitutionality as it attempts to regulate the workplace. Minnesota Senator Hubert Humphrey corrected this notion: "there is nothing in [Title VII] that will give power to the Commission to require hiring, firing, and promotion to meet a racial 'quota.' [. . .] Title VII is designed to encourage the hiring on basis of ability and qualifications, not race or religion." Title VII prohibits discrimination. Humphrey was the silent hero of the bill's passing through Congress. He pledged that the bill required no quotas, just nondiscrimination. Doing so, he convinced many pro-business Republicans, including Senate Minority Leader Everett Dirksen (IL) to support Title VII.:78–80

Who was one of the key members that Humphrey managed to convince to support the bill?
Answer: Everett Dirksen

The most accurate timekeeping devices are atomic clocks, which are accurate to seconds in many millions of years, and are used to calibrate other clocks and timekeeping instruments. Atomic clocks use the frequency of electronic transitions in certain atoms to measure the second. One of the most common atoms used is caesium, most modern atomic clocks probe caesium with microwaves to determine the frequency of these electron vibrations. Since 1967, the International System of Measurements bases its unit of time, the second, on the properties of caesium atoms. SI defines the second as 9,192,631,770 cycles of the radiation that corresponds to the transition between two electron spin energy levels of the ground state of the 133Cs atom.

Which timekeeping devices are the most accurate?
Answer: atomic clocks

The period saw several important technical innovations, like the principle of linear perspective found in the work of Masaccio, and later described by Brunelleschi. Greater realism was also achieved through the scientific study of anatomy, championed by artists like Donatello. This can be seen particularly well in his sculptures, inspired by the study of classical models. As the centre of the movement shifted to Rome, the period culminated in the High Renaissance masters da Vinci, Michelangelo and Raphael.

Along with da Vinci, who were two other artists regarded as masters of the High Renaissance?
Answer:
Michelangelo and Raphael
