The problem: Answer a question about this article:
Modern morphology recognizes a continuum between the major morphological categories of root, stem (caulome), leaf (phyllome) and trichome. Furthermore, it emphasizes structural dynamics. Modern systematics aims to reflect and discover phylogenetic relationships between plants. Modern Molecular phylogenetics largely ignores morphological characters, relying on DNA sequences as data. Molecular analysis of DNA sequences from most families of flowering plants enabled the Angiosperm Phylogeny Group to publish in 1998 a phylogeny of flowering plants, answering many of the questions about relationships among angiosperm families and species. The theoretical possibility of a practical method for identification of plant species and commercial varieties by DNA barcoding is the subject of active current research.
What did the Angiosperm Phylogeny group use determine a phylogeny of flowering plants?
****
The answer: Molecular analysis of DNA

German cinema dates back to the very early years of the medium with the work of Max Skladanowsky. It was particularly influential during the years of the Weimar Republic with German expressionists such as Robert Wiene and Friedrich Wilhelm Murnau.

In the early 20th century, many anthropologists accepted and taught the belief that biologically distinct races were isomorphic with distinct linguistic, cultural, and social groups, while popularly applying that belief to the field of eugenics, in conjunction with a practice that is now called scientific racism. After the Nazi eugenics program, racial essentialism lost widespread popularity. Race anthropologists were pressured to acknowledge findings coming from studies of culture and population genetics, and to revise their conclusions about the sources of phenotypic variation. A significant number of modern anthropologists and biologists in the West came to view race as an invalid genetic or biological designation.
What effect did the Nazi eugenics program have on racial essentialism?
****
The answer: lost widespread popularity

Tajikistan's economy grew substantially after the war. The GDP of Tajikistan expanded at an average rate of 9.6% over the period of 20002007 according to the World Bank data. This improved Tajikistan's position among other Central Asian countries (namely Turkmenistan and Uzbekistan), which seem to have degraded economically ever since. The primary sources of income in Tajikistan are aluminium production, cotton growing and remittances from migrant workers. Cotton accounts for 60% of agricultural output, supporting 75% of the rural population, and using 45% of irrigated arable land. The aluminium industry is represented by the state-owned Tajik Aluminum Company the biggest aluminium plant in Central Asia and one of the biggest in the world.
What is the primary source of income in Tajikistan?
****
The answer:
aluminium production, cotton growing and remittances from migrant workers
