The problem: Answer a question about this article:
In 1998 the Angiosperm Phylogeny Group published a phylogeny for flowering plants based on an analysis of DNA sequences from most families of flowering plants. As a result of this work, many questions, such as which families represent the earliest branches of angiosperms, have now been answered. Investigating how plant species are related to each other allows botanists to better understand the process of evolution in plants. Despite the study of model plants and increasing use of DNA evidence, there is ongoing work and discussion among taxonomists about how best to classify plants into various taxa. Technological developments such as computers and electron microscopes have greatly increased the level of detail studied and speed at which data can be analysed.
What can be learned from DNA sequencing of plants?
****
The answer: evolution in plants

One usage—the more common among linguists—refers to a variety of a language that is a characteristic of a particular group of the language's speakers. The term is applied most often to regional speech patterns, but a dialect may also be defined by other factors, such as social class. A dialect that is associated with a particular social class can be termed a sociolect, a dialect that is associated with a particular ethnic group can be termed as ethnolect, and a regional dialect may be termed a regiolect. According to this definition, any variety of a language constitutes "a dialect", including any standard varieties.
What is the term dialect most often applied to?
****
The answer: regional speech patterns

The problem: Answer a question about this article:
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 Cities—Jerusalem, Tiberias, Hebron, and Safed—and 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.
Where did some Jewish communities settle after they were expelled from Spain?
****
The answer:
Palestine
