Input: Read this: Armenian and Cantonese have aspiration that lasts about as long as English aspirated stops, in addition to unaspirated stops. Korean has lightly aspirated stops that fall between the Armenian and Cantonese unaspirated and aspirated stops as well as strongly aspirated stops whose aspiration lasts longer than that of Armenian or Cantonese. (See voice-onset time.)
Question: Armenian unaspirated stops last longer than whose?

Output: unanswerable

Input: Read this: The Appalachians are also home to two species of fir, the boreal balsam fir (Abies balsamea), and the southern high elevation endemic, Fraser fir (Abies fraseri). Fraser fir is confined to the highest parts of the southern Appalachian Mountains, where along with red spruce it forms a fragile ecosystem known as the Southern Appalachian spruce-fir forest. Fraser fir rarely occurs below 5,500 ft (1,700 m), and becomes the dominant tree type at 6,200 ft (1,900 m). By contrast, balsam fir is found from near sea level to the tree line in the northern Appalachians, but ranges only as far south as Virginia and West Virginia in the central Appalachians, where it is usually confined above 3,900 ft (1,200 m) asl, except in cold valleys. Curiously, it is associated with oaks in Virginia. The balsam fir of Virginia and West Virginia is thought by some to be a natural hybrid between the more northern variety and Fraser fir. While red spruce is common in both upland and bog habitats, balsam fir, as well as black spruce and tamarack, are more characteristic of the latter. However balsam fir also does well in soils with a pH as high as 6.
Question: What is the scientific name of the oak tree?

Output: unanswerable

Input: Read this: The "Lophotrochozoa" hypothesis is also supported by the fact that many phyla within this group, including annelids, molluscs, nemerteans and flatworms, follow a similar pattern in the fertilized egg's development. When their cells divide after the 4-cell stage, descendants of these 4 cells form a spiral pattern. In these phyla the "fates" of the embryo's cells, in other words the roles their descendants will play in the adult animal, are the same and can be predicted from a very early stage. Hence this development pattern is often described as "spiral determinate cleavage".
Question: What phyla is no longer able to make eggs?

Output: unanswerable

Input: Read this: Since the existence of the earliest Jewish diaspora, many Jews have aspired to return to "Zion" and the "Land of Israel", though the amount of effort that should be spent towards such an aim was a matter of dispute. The hopes and yearnings of Jews living in exile are an important theme of the Jewish belief system. After the Jews were expelled from Spain in 1492, some communities settled in Palestine. During the 16th century, Jewish communities struck roots in the Four Holy CitiesJerusalem, Tiberias, Hebron, and Safedand in 1697, Rabbi Yehuda Hachasid led a group of 1,500 Jews to Jerusalem. In the second half of the 18th century, Eastern European opponents of Hasidism, known as the Perushim, settled in Palestine.
Question: Where did some Jewish communities settle after they were expelled from Spain?

Output:
Palestine
