Input: Read this: In addition to tributary relations with the Kushans, the Han Empire received gifts from the Parthian Empire, from a king in modern Burma, from a ruler in Japan, and initiated an unsuccessful mission to Daqin (Rome) in AD 97 with Gan Ying as emissary. A Roman embassy of Emperor Marcus Aurelius (r. 161–180 AD) is recorded in the Hou Hanshu to have reached the court of Emperor Huan of Han (r. AD 146–168) in AD 166, yet Rafe de Crespigny asserts that this was most likely a group of Roman merchants. Other travelers to Eastern-Han China included Buddhist monks who translated works into Chinese, such as An Shigao of Parthia, and Lokaksema from Kushan-era Gandhara, India.
Question: Who reached the court of Emperor Huan in AD 166?

Output: A Roman embassy


Input: Read this: After the September 2011 execution of Troy Davis, believed by many to be innocent, Richard Dieter, the director of the Death Penalty Information Center, said this case was a clear wake-up call to politicians across the United States. He said: "They weren't expecting such passion from people in opposition to the death penalty. There's a widely held perception that all Americans are united in favor of executions, but this message came across loud and clear that many people are not happy with it." Brian Evans of Amnesty International, which led the campaign to spare Davis's life, said that there was a groundswell in America of people "who are tired of a justice system that is inhumane and inflexible and allows executions where there is clear doubts about guilt". He predicted the debate would now be conducted with renewed energy.
Question: Who was the Death Penalty Information Center director?

Output: Richard Dieter

Input: Read this: The transcribed pre-mRNA contains untranslated regions at both ends which contain a ribosome binding site, terminator and start and stop codons. In addition, most eukaryotic open reading frames contain untranslated introns which are removed before the exons are translated. The sequences at the ends of the introns, dictate the splice sites to generate the final mature mRNA which encodes the protein or RNA product.
Question: Where are the ribosome binding site, terminator and start and stop codons located on transcribed pre-mRNA?

Output:
untranslated regions
