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.

Q: Question: How many Nobel Prizes in Physics were awarded before it was given to Leo Esaki? Passage:A tunnel diode or Esaki diode is a type of semiconductor diode that has negative resistance due to the quantum mechanical effect called tunneling. It was invented in August 1957 by Leo Esaki, Yuriko Kurose, and Takashi Suzuki when they were working at Tokyo Tsushin Kogyo, now known as Sony. In 1973, Esaki received the Nobel Prize in Physics, jointly with Brian Josephson, for discovering the electron tunneling effect used in these diodes. Robert Noyce independently devised the idea of a tunnel diode while working for William Shockley, but was discouraged from pursuing it. Tunnel diodes were first manufactured by Sony in 1957, followed by General Electric and other companies from about 1960, and are still made in low volume today.

Q: Question: Is there a difference in the age of the horses entered to compete in the Royal Lodge Stakes compared to the Sussex Stakes? Passage:Cecil's success in 2011 was partly due to his training of the Khalid Abdullah-owned Frankel. In the 2010 season Frankel won the Royal Lodge Stakes and Group One Dewhurst Stakes. The following year he continued unbeaten, winning the Greenham Stakes, the 2,000 Guineas, the St. James's Palace Stakes at Royal Ascot, the Sussex Stakes and the Queen Elizabeth II Stakes. His six length victory in the 2,000 Guineas was described as "one of the greatest displays on a British racecourse". After his win in the Sussex Stakes Cecil himself described Frankel as "the best horse I've ever seen". Timeform and the International Federation of Horseracing Authorities rated him the best horse in the world. In his four-year-old season Frankel won the Group One Lockinge Stakes at Newbury before an eleven length victory in the Queen Anne Stakes at Royal Ascot, described in one national newspaper as "possibly the best single performance by any horse, on any track, since three Arabian stallions were imported into Britain to found the thoroughbred breed in the early years of the 18th century". Timeform raised their rating to 147, making Frankel the highest rated horse in their history. He won a second Sussex Stakes, at odds of 1–20, and then stepped up in distance to win by seven lengths the Juddmonte International Stakes at York over 10 furlongs. In October 2012 Frankel won the Champion Stakes at Ascot to finish his career unbeaten. "He's the best I've ever had, the best I've ever seen", Cecil told the BBC after the race, "I'd be very surprised if there's ever been a better."


A: In the 2010 season Frankel won the Royal Lodge Stakes and Group One Dewhurst Stakes

Q: Question: What country is the National Institute of Health located in? 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.
