Context and question: Plant responses to climate and other environmental changes can inform our understanding of how these changes affect ecosystem function and productivity. For example, plant phenology can be a useful proxy for temperature in historical climatology, and the biological impact of climate change and global warming. Palynology, the analysis of fossil pollen deposits in sediments from thousands or millions of years ago allows the reconstruction of past climates. Estimates of atmospheric CO2 concentrations since the Palaeozoic have been obtained from stomatal densities and the leaf shapes and sizes of ancient land plants. Ozone depletion can expose plants to higher levels of ultraviolet radiation-B (UV-B), resulting in lower growth rates. Moreover, information from studies of community ecology, plant systematics, and taxonomy is essential to understanding vegetation change, habitat destruction and species extinction.
How can climate changes be determined from soil?
Answer: fossil pollen deposits in sediments
Context and question: Biographers Blundy and Lycett believed that he was "a populist at heart." Throughout Libya, crowds of supporters would turn up to public events at which he appeared; described as "spontaneous demonstrations" by the government, there are recorded instances of groups being coerced or paid to attend. He was typically late to public events, and would sometimes not show up at all. Although Bianco thought he had a "gift for oratory", he was considered a poor orator by biographers Blundy and Lycett. Biographer Daniel Kawczynski noted that Gaddafi was famed for his "lengthy, wandering" speeches, which typically involved criticising Israel and the U.S.
Who stated that Gaddafi was a gifted speaker?
Answer: Bianco
Context and question: Architects such as Mies van der Rohe, Philip Johnson and Marcel Breuer worked to create beauty based on the inherent qualities of building materials and modern construction techniques, trading traditional historic forms for simplified geometric forms, celebrating the new means and methods made possible by the Industrial Revolution, including steel-frame construction, which gave birth to high-rise superstructures. By mid-century, Modernism had morphed into the International Style, an aesthetic epitomized in many ways by the Twin Towers of New York's World Trade Center designed by Minoru Yamasaki.
What is an example of International Style?
Answer:
Twin Towers
