Context and question: A public genome sequencing effort of cotton was initiated in 2007 by a consortium of public researchers. They agreed on a strategy to sequence the genome of cultivated, tetraploid cotton. "Tetraploid" means that cultivated cotton actually has two separate genomes within its nucleus, referred to as the A and D genomes. The sequencing consortium first agreed to sequence the D-genome relative of cultivated cotton (G. raimondii, a wild Central American cotton species) because of its small size and limited number of repetitive elements. It is nearly one-third the number of bases of tetraploid cotton (AD), and each chromosome is only present once.[clarification needed] The A genome of G. arboreum would be sequenced next. Its genome is roughly twice the size of G. raimondii's. Part of the difference in size between the two genomes is the amplification of retrotransposons (GORGE). Once both diploid genomes are assembled, then research could begin sequencing the actual genomes of cultivated cotton varieties. This strategy is out of necessity; if one were to sequence the tetraploid genome without model diploid genomes, the euchromatic DNA sequences of the AD genomes would co-assemble and the repetitive elements of AD genomes would assembly independently into A and D sequences respectively. Then there would be no way to untangle the mess of AD sequences without comparing them to their diploid counterparts.
What type of genome must be sequenced first to prevent confusion before GORGE?
Answer: unanswerable
Context and question: Parallel to the military developments emerged also a constantly more elaborate chivalric code of conduct for the warrior class. This new-found ethos can be seen as a response to the diminishing military role of the aristocracy, and gradually it became almost entirely detached from its military origin. The spirit of chivalry was given expression through the new (secular) type of chivalric orders; the first of these was the Order of St. George, founded by Charles I of Hungary in 1325, while the best known was probably the English Order of the Garter, founded by Edward III in 1348.
What was the chivalric order established by Edward III in 1438?
Answer: unanswerable
Context and question: In 179 BC Philip died. His talented and ambitious son, Perseus, took the throne and showed a renewed interest in conquering Greece. With her Greek allies facing a major new threat, Rome declared war on Macedonia again, starting the Third Macedonian War. Perseus initially had some success against the Romans. However, Rome responded by sending a stronger army. This second consular army decisively defeated the Macedonians at the Battle of Pydna in 168 BC and the Macedonians duly capitulated, ending the war.
In what year did Philip pass away?
Answer:
179 BC
