Problem: Background: Marian Anderson (February 27, 1897 - April 8, 1993) was an African-American contralto and one of the most celebrated singers of the twentieth century. Music critic Alan Blyth said: "Her voice was a rich, vibrant contralto of intrinsic beauty." Most of her singing career was spent performing in concert and recital in major music venues and with famous orchestras throughout the United States and Europe between 1925 and 1965. Although offered roles with many important European opera companies, Anderson declined, as she had no training in acting.
Context: In 1933, Anderson made her European debut in a concert at Wigmore Hall in London, where she was received enthusiastically. She spent the early 1930s touring throughout Europe where she did not encounter the racial prejudices she had experienced in America. In the summer of 1930, she went to Scandinavia, where she met the Finnish pianist Kosti Vehanen who became her regular accompanist and her vocal coach for many years. She also met Jean Sibelius through Vehanen after he had heard her in a concert in Helsinki. Moved by her performance, Sibelius invited them to his home and asked his wife to bring champagne in place of the traditional coffee. Sibelius commented to Anderson of her performance that he felt that she had been able to penetrate the Nordic soul. The two struck up an immediate friendship, which further blossomed into a professional partnership, and for many years Sibelius altered and composed songs for Anderson to perform. He created a new arrangement of the song "Solitude" and dedicated it to Anderson in 1939. Originally The Jewish Girl's Song from his 1906 incidental music to Belshazzar's Feast, it later became the "Solitude" section of the orchestral suite derived from the incidental music. In 1934, impresario Sol Hurok offered Anderson a better contract than she previously had with Arthur Judson. He became her manager for the rest of her performing career and through his persuasion she came back to perform in America. In 1935, Anderson made her first recital appearance in New York at Town Hall, which received highly favorable reviews by music critics. She spent the next four years touring throughout the United States and Europe. She was offered opera roles by several European houses but, due to her lack of acting experience, Anderson declined all of those offers. She did, however, record a number of opera arias in the studio, which became bestsellers. Anderson, accompanied by Vehanen, continued to tour throughout Europe during the mid-1930s. She visited Eastern European capitals and Russia and returned again to Scandinavia, where "Marian fever" had spread to small towns and villages where she had thousands of fans. She quickly became a favorite of many conductors and composers of major European orchestras. During a 1935 tour in Salzburg, the conductor Arturo Toscanini told her she had a voice "heard once in a hundred years". In the late 1930s, Anderson gave about 70 recitals a year in the United States. Although by then quite famous, her stature did not completely end the prejudice she confronted as a young black singer touring the United States. She was still denied rooms in certain American hotels and was not allowed to eat in certain American restaurants. Because of this discrimination, Albert Einstein, a champion of racial tolerance, hosted Anderson on many occasions, the first being in 1937 when she was denied a hotel before performing at Princeton University. She last stayed with him months before he died in 1955.
Question: Was there ever any conflicts?
Answer: her stature did not completely end the prejudice she confronted as a young black singer touring the United States.

Problem: Background: For the upcoming film about the superhero character, see Aquaman (film). Aquaman is a fictional superhero appearing in American comic books published by DC Comics. Created by Paul Norris and Mort Weisinger, the character debuted in More Fun Comics #73 (November 1941). Initially a backup feature in DC's anthology titles, Aquaman later starred in several volumes of a solo comic book series.
Context: Aquaman's adventures continued to be published in Adventure Comics through the 1940s and 1950s, as one of the few superheroes to last through the 1950s in continuous publication. Starting in the late 1950s, new elements to Aquaman's backstory were introduced, with various new supporting characters added and several adjustments made to the character, his origins, his powers, and persona. The first of these elements was the story "Aquaman's Undersea Partner" in Adventure Comics #229 (October 1956), where his octopus sidekick, Topo, was first introduced. This and subsequent elements were later, after the establishment of DC's multiverse in the 1960s, attributed to the Aquaman of Earth-One. In Adventure Comics #260 (May 1959) and subsequent Silver Age comics, it was revealed that Aquaman was Arthur Curry, the son of Tom Curry, a lighthouse keeper, and Atlanna, a water-breathing outcast from the lost, underwater city of Atlantis. Due to his heritage, Aquaman discovers as a youth that he possesses various superhuman abilities, including the powers of surviving underwater, communication with sea life, and tremendous swimming prowess. Eventually, Arthur decided to use his talents to become the defender of the Earth's oceans. It was later revealed that he had, in his youth, adventured as Aquaboy and on one occasion, met Superboy, Earth's only other publicly active superpowered hero at the time. When Arthur grew up, he called himself "Aquaman". It was later revealed that after Atlanna's death, Tom Curry met and married an ordinary human woman and had a son named Orm Curry, Aquaman's half-brother. Orm grew up as a troubled youth in the shadow of his brother, who constantly bailed him out of trouble with the law. He grew to hate Aquaman not only for the powers that he could never possess but also because he believed that their father would always favor Aquaman. Orm disappeared after becoming an amnesiac and would resurface years later as Aquaman's nemesis, Ocean Master. Aquaman's ability to talk with fish eventually expanded to full-fledged telepathic communication with sea creatures even from great distances. He also retroactively developed a specific weakness akin to Superman's vulnerability to kryptonite or Green Lantern's vulnerability to the color yellow: Aquaman had to come into contact with water at least once per hour, or he would die. Prior to this story, Aquaman could exist both in and out of water indefinitely.
Question: what other powers did he have?
Answer:
communication with sea life, and tremendous swimming prowess.
