In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it. Your job is to determine which sentence(s) from the passage can be used to search for further information needed to answer the question.

[EX Q]: Question: Who was Roland I's mother? Passage:Roland I was born around 1215 into the gens Rátót as the son of Dominic I, who served as Master of the treasury from 1238 to 1240. He was killed in the Battle of Mohi in 1241. The ancestors of the kindred were two Norman knights (Oliver and Rathold) from Caserta, Naples, who settled down in Hungary around 1097 during the reign of Coloman, King of Hungary. Roland's earliest known ancestor was his great-grandfather Leustach I Rátót, Voivode of Transylvania in the second half of the 12th century. Roland had three brothers, Stephen, the forefather of the Pásztói, Tari and Kakas de Kaza noble families. The Putnoki family came from Oliver I. Leustach II was the father of Palatine Roland II Rátót and also the ancestor of the Jolsvai, Serkei and Feledi branches. Their only unidentified sister married Maurice II Pok whom the influential baron Nicholas Pok originated.

[EX A]: Roland I was born around 1215 into the gens Rátót as the son of Dominic I, who served as Master of the treasury from 1238 to 1240

[EX Q]: 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.
