Input: Consider Input: Passage: Virginia has the highest concentration of technology workers of any state, and the fourth-highest number of technology workers after California, Texas, and New York. Computer chips became the state's highest-grossing export in 2006, surpassing its traditional top exports of coal and tobacco combined, reaching a total export value of $717 million in 2015. Northern Virginia, once considered the state's dairy capital, now hosts software, communication technology, defense contracting companies, particularly in the Dulles Technology Corridor.
The state has the highest average and peak Internet speeds in the United States, with the third-highest worldwide. Northern Virginia's data centers can carry up to 70% of the nation's Internet traffic, and in 2015 the region was the largest and fastest growing data center market in the nation.Forbes magazine has named Virginia the best state in the nation for business five times, and included it in their top five in 2018, as did CNBC in their America's Top States For Business 2018 rankings, with its deductions being mainly for the high cost of living. Additionally, in 2014 a survey of 12,000 small business owners found Virginia to be one of the most friendly states for small businesses. Virginia has 23 Fortune 500 companies, ranking the state sixth nationwide. Tysons Corner is one of the largest business districts in the nation.
Tourism in Virginia supported an estimated 210,000 jobs and generated $21.2 billion in 2012. Arlington County is the top tourist destination in the state by domestic spending, followed by Fairfax County, Loudoun County, and Virginia Beach. 
Question: What are the top four states with the highest concentration of technology workers?

Output: Virginia.


Input: Consider Input: Passage: Holkham was built by 1st Earl of Leicester, Thomas Coke, who was born in 1697. A cultivated and wealthy man, Coke made the Grand Tour in his youth and was away from England for six years between 1712 and 1718. It is likely he met both Burlington—the aristocratic architect at the forefront of the Palladian revival movement in England—and William Kent in Italy in 1715, and that in the home of Palladianism the idea of the mansion at Holkham was conceived. Coke returned to England, not only with a newly acquired library, but also an art and sculpture collection with which to furnish his planned new mansion. However, after his return, he lived a feckless life, preoccupying himself with drinking, gambling and hunting, and being a leading supporter of cockfighting.  He made a disastrous investment in the South Sea Company and when the South Sea Bubble burst in 1720, the resultant losses delayed the building of Coke's planned new country estate for over ten years. Coke, who had been made Earl of Leicester in 1744, died in 1759—five years before the completion of Holkham—having never fully recovered his financial losses. Thomas's wife, Lady Margaret Tufton, Countess of Leicester (1700–1775), would oversee the finishing and furnishing of the house.Although Colen Campbell was employed by Thomas Coke in the early 1720s, the oldest existing working and construction plans for Holkham were drawn by Matthew Brettingham, under the supervision of Thomas Coke, in 1726. These followed the guidelines and ideals for the house as defined by Kent and Burlington. The Palladian revival style chosen was at this time making its return in England. The style made a brief appearance in England before the Civil War, when it was introduced by Inigo Jones. However, following the Restoration it was replaced in popular favour by the Baroque style. The "Palladian revival", popular in the 18th century, was loosely based on the appearance of the works of the 16th-century Italian architect Andrea Palladio. However it did not adhere to Palladio's strict rules of proportion. The style eventually evolved into what is generally referred to as Georgian, still popular in England today. It was the chosen style for numerous houses in both town and country, although Holkham is exceptional for both its severity of design and for being closer than most in its adherence to Palladio's ideals. 
Question: What was the name of the style that made a brief appearance in England before the Cival War?

Output: The Palladian revival style.


Input: Consider Input: Passage: Stalin's death in 1953 was the biggest step toward Shostakovich's rehabilitation as a creative artist, which was marked by his Tenth Symphony. It features a number of musical quotations and codes (notably the DSCH and Elmira motifs, Elmira Nazirova being a pianist and composer who had studied under Shostakovich in the year before his dismissal from the Moscow Conservatory), the meaning of which is still debated, while the savage second movement, according to Testimony, is intended as a musical portrait of Stalin. The Tenth ranks alongside the Fifth and Seventh as one of Shostakovich's most popular works. 1953 also saw a stream of premieres of the "desk drawer" works.
During the forties and fifties, Shostakovich had close relationships with two of his pupils, Galina Ustvolskaya and Elmira Nazirova. In the background to all this remained Shostakovich's first, open marriage to Nina Varzar until her death in 1954. He taught Ustvolskaya from 1937 to 1947. The nature of their relationship is far from clear: Mstislav Rostropovich described it as "tender". Ustvolskaya rejected a proposal of marriage from him after Nina's death. Shostakovich's daughter, Galina, recalled her father consulting her and Maxim about the possibility of Ustvolskaya becoming their stepmother. Ustvolskaya's friend Viktor Suslin said that she had been "deeply disappointed" in Shostakovich by the time of her graduation in 1947. The relationship with Nazirova seems to have been one-sided, expressed largely through his letters to her, and can be dated to around 1953 to 1956. He married his second wife, Komsomol activist Margarita Kainova, in 1956; the couple proved ill-matched, and divorced three years later.
In 1954, Shostakovich wrote the Festive Overture, opus 96; it was used as the theme music for the 1980 Summer Olympics. (His '"Theme from the film Pirogov, Opus 76a: Finale" was played as the cauldron was lit at the 2004 Summer Olympics in Athens, Greece.)
In 1959, Shostakovich appeared on stage in Moscow at the end of a concert performance of his Fifth Symphony, congratulating Leonard Bernstein and the New York Philharmonic Orchestra for their performance (part of a concert tour of the Soviet Union). Later that year, Bernstein and the New York Philharmonic recorded the symphony in Boston for Columbia Records. 
Question: What is the last name of the man that the composer who married Margarita Kainova congratulate on stage in Moscow in 1959?


Output: Bernstein.
