Question: Question: Which of the Churchill brothers died first? Passage:Lady Eden was born in 1920, the daughter of Major Jack Spencer-Churchill (18801947), the younger brother of Winston Churchill, by his marriage to Lady Gwendoline ("Goonie") Bertie (18851941), a daughter of the 7th Earl of Abingdon, who had been married in 1908. She is thus a niece of Winston Churchill, who was Prime Minister during the Second World War, and a granddaughter of Lord Randolph Churchill, Chancellor of the Exchequer 188687, and his wife the American society beauty Jennie Jerome. Her paternal great-grandfather was the 7th Duke of Marlborough, and her maternal great-great-grandfather the 3rd Marquess of Londonderry, half-brother of the 2nd Marquess, who, as Viscount Castlereagh was Foreign Secretary during the Congress of Vienna of 1815 that followed the Napoleonic Wars.

Question: 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.

Question: Question: What is the birth date of Mondlane's wife who he married after he earned his Masters? Passage:The fourth of 16 sons of a tribal chief of the Bantu-speaking Tsonga, Mondlane was born in "N'wajahani", district of Mandlakazi in the province of Gaza," in Portuguese East Africa (Mozambique) in 1920. He worked as a shepherd until the age of 12. He attended several different primary schools before enrolling in a SwissPresbyterian school near Manjacaze. However, he ended his secondary education in the same organisation's church school at Lemana College at Village above Elim Hospital in the Transvaal (Limpopo Province), South Africa. He then spent one year at the Jan H. Hofmeyr School of Social Work before enrolling in Witwatersrand University in Johannesburg but was expelled from South Africa after only a year, in 1949, following the rise of the Apartheid government. In June 1950 Mondlane entered the University of Lisbon, at Lisbon, the capital of Portugal. By Mondlane's request, he was transferred to the United States, where he entered Oberlin College in Ohio at the age of 31, under a Phelps Stokes scholarship. Mondlane enrolled at Oberlin College in Oberlin, Ohio, in 1951, starting as a junior, and in 1953 he obtained a degree in anthropology and sociology. He continued his studies at Northwestern University in Evanston, Illinois. Mondlane earned an MA and a PhD from Northwestern University and married Janet Rae Johnson, a white American woman from Indiana who then lived in the Chicago suburbs.
