This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) its answer is a continuous text span from the paragraph. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.

Ex Input:
The state is also a host to a large population of birds which include endemic species and migratory species: greater roadrunner Geococcyx californianus, cactus wren Campylorhynchus brunneicapillus, Mexican jay Aphelocoma ultramarina, Steller's jay Cyanocitta stelleri, acorn woodpecker Melanerpes formicivorus, canyon towhee Pipilo fuscus, mourning dove Zenaida macroura, broad-billed hummingbird Cynanthus latirostris, Montezuma quail Cyrtonyx montezumae, mountain trogon Trogon mexicanus, turkey vulture Cathartes aura, and golden eagle Aquila chrysaetos. Trogon mexicanus is an endemic species found in the mountains in Mexico; it is considered an endangered species[citation needed] and has symbolic significance to Mexicans.

Ex Output:
The state hosts populations of birds of both endemic species and what?


Ex Input:
The brushless wound-rotor synchronous doubly-fed (BWRSDF) machine is the only electric machine with a truly dual ported transformer circuit topology (i.e., both ports independently excited with no short-circuited port). The dual ported transformer circuit topology is known to be unstable and requires a multiphase slip-ring-brush assembly to propagate limited power to the rotor winding set. If a precision means were available to instantaneously control torque angle and slip for synchronous operation during motoring or generating while simultaneously providing brushless power to the rotor winding set, the active current of the BWRSDF machine would be independent of the reactive impedance of the transformer circuit and bursts of torque significantly higher than the maximum operating torque and far beyond the practical capability of any other type of electric machine would be realizable. Torque bursts greater than eight times operating torque have been calculated.

Ex Output:
What is the only device with dual ported transformer circuit topology?


Ex Input:
In 1960, non-Hispanic whites represented 80% of Miami-Dade county's population. In 1970, the Census Bureau reported Miami's population as 45.3% Hispanic, 32.9% non-Hispanic White, and 22.7% Black. Miami's explosive population growth has been driven by internal migration from other parts of the country, primarily up until the 1980s, as well as by immigration, primarily from the 1960s to the 1990s. Today, immigration to Miami has slowed significantly and Miami's growth today is attributed greatly to its fast urbanization and high-rise construction, which has increased its inner city neighborhood population densities, such as in Downtown, Brickell, and Edgewater, where one area in Downtown alone saw a 2,069% increase in population in the 2010 Census. Miami is regarded as more of a multicultural mosaic, than it is a melting pot, with residents still maintaining much of, or some of their cultural traits. The overall culture of Miami is heavily influenced by its large population of Hispanics and blacks mainly from the Caribbean islands.

Ex Output:

What percentage of Miami-Dade's population was non-Hispanic white in 1960?
