Question: How long had the United Nations been in existence when Gross was appointed? Passage:On October 11, 1949, United States Secretary of State Dean Acheson appointed Gross as the United States' deputy delegate to the United Nations. Only two months later, the chief delegate, Warren Austin, took a leave of absence, and Gross took over as acting head of the U.S. delegation to the U.N. The major issue facing the United Nations at that time was the Soviet Union's proposal that, with the conclusion of the Chinese Civil War, the Communist People's Republic of China should replace the Republic of China on the United Nations Security Council. On January 13, 1950, the Soviet delegate, Jacov Malik, walked out of the Security Council in protest. Malik remained absent for several months, and as such the Soviet Union failed to exercise its veto power to block United Nations Security Council Resolution 82, which condemned North Korea at the beginning of the Korean War; on behalf of the U.S., Gross voted in favor of the resolution. In fall 1950, Warren Austin returned from his leave of absence, and Gross continued to serve as Austin's deputy until 1953.

Question: How many people of Chinese origin lived in New York the year the Chinese Exclusion Act went into effect? Passage:The first Chinese immigrants came to lower Manhattan around 1870, looking for the "gold" America had to offer. By 1880, the enclave around Five Points was estimated to have from 200 to as many as 1,100 members. However, the Chinese Exclusion Act, which went into effect in 1882, caused an abrupt decline in the number of Chinese who immigrated to New York and the rest of the United States. Later, in 1943, the Chinese were given a small quota, and the community's population gradually increased until 1968, when the quota was lifted and the Chinese American population skyrocketed. Today, the Manhattan Chinatown () is home to the largest concentration of Chinese people in the Western Hemisphere and is one of the oldest ethnic Chinese enclaves outside of Asia. Within Manhattan's expanding Chinatown lies a "Little Fuzhou" on East Broadway and surrounding streets, occupied predominantly by immigrants from the Fujian Province of Mainland China. Areas surrounding the "Little Fuzhou" consist mostly of Cantonese immigrants from Guangdong Province, the earlier Chinese settlers, and in some areas moderately of Cantonese immigrants. In the past few years, however, the Cantonese dialect that has dominated Chinatown for decades is being rapidly swept aside by Mandarin, the national language of China and the lingua franca of most of the latest Chinese immigrants. The energy and population of Manhattan's Chinatown are fueled by relentless, massive immigration from Mainland China, both legal and illegal in origin, propagated in large part by New York's high density, extensive mass transit system, and huge economic marketplace.

Ex Output:

Question: What year was the first case of HIV/AIDS reported? Passage:While working at the National Institute of Health, Lisziewicz worked to find a gene therapy approach to treat HIV/AIDS. She based her research on discovering if small portions of gene-stopping DNA (called antisense oligonucleotides) could be created to bind up the viral RNA in retroviruses like HIV so that the virus could not make more copies of itself to continue the infection. Small pieces of messenger RNA (or mRNA) carry a copy of the cell's DNA to the ribosomes where the mRNA directs the ribosomes to create the proteins that the cells need. Viruses (like HIV) have their own set of mRNA, and they use the ribosomes of the cell they infected to make new viruses to propagate the infection throughout the body. Lisziewicz's idea was to create antisense oligonucleotides that are complementary to the HIV's viral mRNA. These complementary DNA pieces can bind to the HIV viral mRNA and prevent the HIV virus from replicating itself. The use of antisense oligonucleotides worked very well in cell cultures, and was quickly transferred to clinical trials.
