Given the following passage "The fossil record indicates that birds are the last surviving dinosaurs, having evolved from feathered ancestors within the theropod group of saurischian dinosaurs. True birds first appeared during the Cretaceous period, around 100 million years ago. DNA-based evidence finds that birds diversified dramatically around the time of the CretaceousPaleogene extinction event that killed off all other dinosaurs. Birds in South America survived this event and then migrated to other parts of the world via multiple land bridges while diversifying during periods of global cooling. Primitive bird-like dinosaurs that lie outside class Aves proper, in the broader group Avialae, have been found dating back to the mid-Jurassic period. Many of these early "stem-birds", such as Archaeopteryx, were not yet capable of fully powered flight, and many retained primitive characteristics like toothy jaws in place of beaks, and long bony tails.", answer the following question. Note that the answer is present within the text. Question: What have scientists used to learn more about the timeline for birds' evolution?
Ans: DNA-based evidence

Given the following passage "The GameCube and Wii versions feature several minor differences in their controls. The Wii version of the game makes use of the motion sensors and built-in speaker of the Wii Remote. The speaker emits the sounds of a bowstring when shooting an arrow, Midna's laugh when she gives advice to Link, and the series' trademark "chime" when discovering secrets. The player controls Link's sword by swinging the Wii Remote. Other attacks are triggered using similar gestures with the Nunchuk. Unique to the GameCube version is the ability for the player to control the camera freely, without entering a special "lookaround" mode required by the Wii; however, in the GameCube version, only two of Link's secondary weapons can be equipped at a time, as opposed to four in the Wii version.[g]", answer the following question. Note that the answer is present within the text. Question: What are the two visual differences?
Ans: GameCube version is the ability for the player to control the camera freely, without entering a special "lookaround" mode required by the Wii

Given the following passage "The Rule of Law is especially important as an influence on the economic development in developing and transitional countries. To date, the term "rule of law" has been used primarily in the English-speaking countries, and it is not yet fully clarified even with regard to such well-established democracies as, for instance, Sweden, Denmark, France, Germany, or Japan. A common language between lawyers of common law and civil law countries as well as between legal communities of developed and developing countries is critically important for research of links between the rule of law and real economy.", answer the following question. Note that the answer is present within the text. Question: With Norway and Sweden, __ is part of the Scandinavian Airlines flag carrier.

Given the following passage "Muammar Gaddafi was born in a tent near Qasr Abu Hadi, a rural area outside the town of Sirte in the deserts of western Libya. His family came from a small, relatively un-influential tribal group called the Qadhadhfa, who were Arabized Berber in heritage. His father, Mohammad Abdul Salam bin Hamed bin Mohammad, was known as Abu Meniar (died 1985), and his mother was named Aisha (died 1978); Abu Meniar earned a meager subsistence as a goat and camel herder. Nomadic Bedouins, they were illiterate and kept no birth records. As such, Gaddafi's date of birth is not known with certainty, and sources have set it in 1942 or in the spring of 1943, although biographers Blundy and Lycett noted that it could have been pre-1940. His parents' only surviving son, he had three older sisters. Gaddafi's upbringing in Bedouin culture influenced his personal tastes for the rest of his life. He repeatedly expressed a preference for the desert over the city and retreated to the desert to meditate.", answer the following question. Note that the answer is present within the text. Question: Who is Aisha's son?
