Question: "Birds can fly over five thousand what?" Context: "The ability of birds to return to precise locations across vast distances has been known for some time; in an experiment conducted in the 1950s a Manx shearwater released in Boston returned to its colony in Skomer, Wales, within 13 days, a distance of 5,150 km (3,200 mi). Birds navigate during migration using a variety of methods. For diurnal migrants, the sun is used to navigate by day, and a stellar compass is used at night. Birds that use the sun compensate for the changing position of the sun during the day by the use of an internal clock. Orientation with the stellar compass depends on the position of the constellations surrounding Polaris. These are backed up in some species by their ability to sense the Earth's geomagnetism through specialised photoreceptors." Answer:

Question: "What is hematite?" Context: "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." Answer:
----
Answer: forms of iron oxide

Question: "Who was attacked by Nasser supporters using a form of art?" Context: "Nasser's street following was still too small to sustain his plans for reform and to secure him in office. To promote himself and the Liberation Rally, he gave speeches in a cross-country tour, and imposed controls over the country's press by decreeing that all publications had to be approved by the party to prevent "sedition". Both Umm Kulthum and Abdel Halim Hafez, the leading Arab singers of the era, performed songs praising Nasser's nationalism. Others produced plays denigrating his political opponents. According to his associates, Nasser orchestrated the campaign himself. Arab nationalist terms such "Arab homeland" and "Arab nation" frequently began appearing in his speeches in 195455, whereas prior he would refer to the Arab "peoples" or the "Arab region". In January 1955, the RCC appointed him as their president, pending national elections." Answer:

his political opponents
