QUES: In 1957, the state of Arkansas refused to honor a federal court order to integrate their public school system stemming from the Brown decision. Eisenhower demanded that Arkansas governor Orval Faubus obey the court order. When Faubus balked, the president placed the Arkansas National Guard under federal control and sent in the 101st Airborne Division. They escorted and protected nine black students' entry to Little Rock Central High School, an all-white public school, for the first time since the Reconstruction Era. Martin Luther King Jr. wrote to Eisenhower to thank him for his actions, writing "The overwhelming majority of southerners, Negro and white, stand firmly behind your resolute action to restore law and order in Little Rock".
What military unit was sent from outside of Arkansas to oversee desegregation?

ANS: 101st Airborne Division

QUES: Manifold vacuum can be used to drive accessories on automobiles. The best-known application is the vacuum servo, used to provide power assistance for the brakes. Obsolete applications include vacuum-driven windscreen wipers and Autovac fuel pumps. Some aircraft instruments (Attitude Indicator (AI) and the Heading Indicator (HI)) are typically vacuum-powered, as protection against loss of all (electrically powered) instruments, since early aircraft often did not have electrical systems, and since there are two readily available sources of vacuum on a moving aircraft—the engine and an external venturi. Vacuum induction melting uses electromagnetic induction within a vacuum.
What no longer used accessories were powered by vacuum?

ANS: vacuum-driven windscreen wipers and Autovac fuel pumps

QUES: Since the Spanish transition to democracy (1975–1982), Catalan has been institutionalizated as an official language, language of education, and language of mass media; all of which have contributed to its increased prestige. In Catalonia, there is no parallel of a large, bilingual, European, non-state speech community. The teaching of Catalan is mandatory in all schools, but it is possible to use Spanish for studying in the public education system of Catalonia in two situations, if the teacher assigned to a class chooses to use Spanish, or during the learning process of one or some recently arrived students.  There is also some intergenerational shift towards Catalan.
Besides as an official  and an educational language, where else is Catalan the prefered language?

mass media
