Question: In recent years, there has been a rise of indigenous movements in the Americas (mainly South America). These are rights-driven groups that organize themselves in order to achieve some sort of self-determination and the preservation of their culture for their peoples. Organizations like the Coordinator of Indigenous Organizations of the Amazon River Basin and the Indian Council of South America are examples of movements that are breaking the barrier of borders in order to obtain rights for Amazonian indigenous populations everywhere. Similar movements for indigenous rights can also be seen in Canada and the United States, with movements like the International Indian Treaty Council and the accession of native Indian group into the Unrepresented Nations and Peoples Organization.
Is there an answer to this question: Where has there been a rise of indigenous movements in recent years?

Answer: the Americas (mainly South America)


Question: By the end of the Mesozoic era, the Appalachian Mountains had been eroded to an almost flat plain. It was not until the region was uplifted during the Cenozoic Era that the distinctive topography of the present formed. Uplift rejuvenated the streams, which rapidly responded by cutting downward into the ancient bedrock. Some streams flowed along weak layers that define the folds and faults created many millions of years earlier. Other streams downcut so rapidly that they cut right across the resistant folded rocks of the mountain core, carving canyons across rock layers and geologic structures.
Is there an answer to this question: What defined the folds and faults?

Answer: unanswerable


Question: A further example is the goby fish, which sometimes lives together with a shrimp. The shrimp digs and cleans up a burrow in the sand in which both the shrimp and the goby fish live. The shrimp is almost blind, leaving it vulnerable to predators when outside its burrow. In case of danger the goby fish touches the shrimp with its tail to warn it. When that happens both the shrimp and goby fish quickly retreat into the burrow. Different species of gobies (Elacatinus spp.) also exhibit mutualistic behavior through cleaning up ectoparasites in other fish.
Is there an answer to this question: What is the species of goby that both lives with a shrimp and cleans up ectoparasites on other fish?

Answer: unanswerable


Question: The starch source in a beer provides the fermentable material and is a key determinant of the strength and flavour of the beer. The most common starch source used in beer is malted grain. Grain is malted by soaking it in water, allowing it to begin germination, and then drying the partially germinated grain in a kiln. Malting grain produces enzymes that convert starches in the grain into fermentable sugars. Different roasting times and temperatures are used to produce different colours of malt from the same grain. Darker malts will produce darker beers.
Is there an answer to this question: What material does the flavour source in beer provide?

Answer:
unanswerable
