Question: "How did the incident change things?"  Context: "The crowd roared in approval and Arab audiences were electrified. The assassination attempt backfired, quickly playing into Nasser's hands. Upon returning to Cairo, he ordered one of the largest political crackdowns in the modern history of Egypt, with the arrests of thousands of dissenters, mostly members of the Brotherhood, but also communists, and the dismissal of 140 officers loyal to Naguib. Eight Brotherhood leaders were sentenced to death, although the sentence of its chief ideologue, Sayyid Qutb, was commuted to a 15-year imprisonment. Naguib was removed from the presidency and put under house arrest, but was never tried or sentenced, and no one in the army rose to defend him. With his rivals neutralized, Nasser became the undisputed leader of Egypt."  Answer:

Question: "What have scientists used to learn more about the timeline for birds' evolution?"  Context: "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 Cretaceous–Paleogene 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."
