Problem: Question: "What is the common cause?" Context: "Interspersed repeats mainly come from transposable elements (TEs), but they also include some protein coding gene families and pseudogenes. Transposable elements are able to integrate into the genome at another site within the cell. It is believed that TEs are an important driving force on genome evolution of higher eukaryotes. TEs can be classified into two categories, Class 1 (retrotransposons) and Class 2 (DNA transposons)." Answer:

A: transposable elements

Problem: Question: "What the root cause of the error related to the PlayStation Network?" Context: "On March 1, 2010 (UTC), many of the original "fat" PlayStation 3 models worldwide were experiencing errors related to their internal system clock. The error had many symptoms. Initially, the main problem seemed to be the inability to connect to the PlayStation Network. However, the root cause of the problem was unrelated to the PlayStation Network, since even users who had never been online also had problems playing installed offline games (which queried the system timer as part of startup) and using system themes. At the same time many users noted that the console's clock had gone back to December 31, 1999. The event was nicknamed the ApocalyPS3, a play on the word apocalypse and PS3, the abbreviation for the PlayStation 3 console." Answer:

A: the root cause of the problem was unrelated to the PlayStation Network

Problem: Question: "In order to ensure that Jesus was no longer alive, what occurred?" Context: "According to the canonical gospels, Jesus, whom Christians believe to be the Son of God as well as the Messiah (Christ), was arrested, tried, and sentenced by Pontius Pilate to be scourged, and finally crucified by the Romans. Jesus was stripped of his clothing and offered wine mixed with gall to drink, before being crucified. He was then hung for six hours (according to Mark's Gospel) between two convicted thieves. During this time, the soldiers affixed a sign to the top of the cross stating "Jesus of Nazareth, King of the Jews" in three languages. They then divided his garments among them, but cast lots for his seamless robe. After Jesus' death they pierced his side with a spear to be certain that he had died. The Bible records seven statements that Jesus made while he was on the cross, as well as several supernatural events that occurred." Answer:

A: they pierced his side with a spear

Problem: Question: "Where do the Tidewater glaciers end up?" Context: "Tidewater glaciers are glaciers that terminate in the sea, including most glaciers flowing from Greenland, Antarctica, Baffin and Ellesmere Islands in Canada, Southeast Alaska, and the Northern and Southern Patagonian Ice Fields. As the ice reaches the sea, pieces break off, or calve, forming icebergs. Most tidewater glaciers calve above sea level, which often results in a tremendous impact as the iceberg strikes the water. Tidewater glaciers undergo centuries-long cycles of advance and retreat that are much less affected by the climate change than those of other glaciers." Answer:

A:
icebergs
