input: Please answer the following: I know that the answer to the question "How bad were Nasser's heart attacks?" is in "Nasser had few personal vices other than chain smoking. He maintained 18-hour workdays and rarely took time off for vacations. The combination of smoking and working long hours contributed to his poor health. He was diagnosed with diabetes in the early 1960s and by the time of his death in 1970, he also had arteriosclerosis, heart disease, and high blood pressure. He suffered two major heart attacks (in 1966 and 1969), and was on bed rest for six weeks after the second episode. State media reported that Nasser's absence from the public view at that time was a result of influenza.". Can you tell me what it is?

input: Please answer the following: I know that the answer to the question "What feature did Africa's collision with Europe obliterate?" is in "South America became linked to North America through the Isthmus of Panama during the Pliocene, bringing a nearly complete end to South America's distinctive marsupial faunas. The formation of the Isthmus had major consequences on global temperatures, since warm equatorial ocean currents were cut off and an Atlantic cooling cycle began, with cold Arctic and Antarctic waters dropping temperatures in the now-isolated Atlantic Ocean. Africa's collision with Europe formed the Mediterranean Sea, cutting off the remnants of the Tethys Ocean. Sea level changes exposed the land-bridge between Alaska and Asia. Near the end of the Pliocene, about 2.58 million years ago (the start of the Quaternary Period), the current ice age began. The polar regions have since undergone repeated cycles of glaciation and thaw, repeating every 40,000–100,000 years.". Can you tell me what it is?

input: Please answer the following: I know that the answer to the question "What happened to the African wild dogs in Eritrea?" is in "It is estimated that there are around 100 elephants left in Eritrea, the most northerly of East Africa's elephants. The endangered African wild dog (Lycaon pictus) was previously found in Eritrea, but is now deemed extirpated from the entire country. In Gash Barka, deadly snakes like saw-scaled viper are common. Puff adder and red spitting cobra are widespread and can be found even in the highlands.In the coastal areas marine species that are common include dolphin, dugong, whale shark, turtles, marlin/swordfish, and manta ray.".

input: Please answer the following: I know that the answer to the question "What is hematite?" is in "In nature, the red color of blood comes from hemoglobin, the iron-containing protein found in the red blood cells of all vertebrates. The red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide. It also causes the red color of the planet Mars. The red sky at sunset and sunrise is caused by an optical effect known as Rayleigh scattering, which, when the sun is low or below the horizon, increases the red-wavelength light that reaches the eye. The color of autumn leaves is caused by pigments called anthocyanins, which are produced towards the end of summer, when the green chlorophyll is no longer produced. One to two percent of the human population has red hair; the color is produced by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin.".
