input: Please answer the following: I read this background article the other day: The major zones in river ecosystems are determined by the river bed's gradient or by the velocity of the current. Faster moving turbulent water typically contains greater concentrations of dissolved oxygen, which supports greater biodiversity than the slow moving water of pools. These distinctions form the basis for the division of rivers into upland and lowland rivers. The food base of streams within riparian forests is mostly derived from the trees, but wider streams and those that lack a canopy derive the majority of their food base from algae. Anadromous fish are also an important source of nutrients. Environmental threats to rivers include loss of water, dams, chemical pollution and introduced species. A dam produces negative effects that continue down the watershed. The most important negative effects are the reduction of spring flooding, which damages wetlands, and the retention of sediment, which leads to loss of deltaic wetlands.  I am facing a new situation today: Two rivers spring from the same mountain. Olt was a fast moving river, while Mures river was slow moving and deep. Both rivers are very important for the local economies.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which river had a food source mostly derived from algae?
++++++++++
output: Mures


input: Please answer the following: I read this background article the other day: Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes.  I am facing a new situation today: Boone county experienced severe weather last week as a result of atmospheric convection. White county to the east experienced some rain but was sheltered from this phenomenon because of the mountain range.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which county experienced more parcel-environment instability?
++++++++++
output: Boone


input: Please answer the following: I read this background article the other day: Alpine tundra occurs at high enough altitude at any latitude. Portions of montane grasslands and shrublands ecoregions worldwide include alpine tundra. Large regions of alpine tundra occur in the North American Cordillera, the Alps and Pyrenees of Europe, the Himalaya and Karakoram of Asia, the Andes of South America, and the Eastern Rift mountains of Africa.Alpine tundra occupies high-mountain summits, slopes, and ridges above timberline. Aspect plays a role as well; the treeline often occurs at higher elevations on warmer equator-facing slopes. Because the alpine zone is present only on mountains, much of the landscape is rugged and broken, with rocky, snowcapped peaks, cliffs, and talus slopes, but also contains areas of gently rolling to almost flat topography.Averaging over many locations and local microclimates, the treeline rises 75 metres (245 ft) when moving 1 degree south from 70 to 50°N, and 130 metres (430 ft) per degree from 50 to 30°N. Between 30°N and 20°S, the treeline is roughly constant, between 3,500 and 4,000 metres (11,500 and 13,100 ft).  I am facing a new situation today: Pete and Laura were learning about Earth's vegetation. Laura read about savannas and subtropical vegetation, while Pete read about alpine tundras.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person read more about shrublands ecoregions worldwide?
++++++++++
output: Pete


input: Please answer the following: I read this background article the other day: Since AM fungi are biotrophic, they are dependent on plants for the growth of their hyphal networks. Growing a cover crop extends the time for AM growth into the autumn, winter, and spring. Promotion of hyphal growth creates a more extensive hyphal network. The mycorrhizal colonization increase found in cover crops systems may be largely attributed to an increase in the extraradical hyphal network that can colonize the roots of the new crop (Boswell et al. 1998). The extraradical mycelia are able to survive the winter, providing rapid spring colonization and early season symbiosis (McGonigle and Miller 1999). This early symbiosis allows plants to tap into the well-established hyphal network and be supplied with adequate phosphorus nutrition during early growth, which greatly improves the crop yield.  I am facing a new situation today: Ted had two farmlands. Hill land had good mycorrhizal colonizationbecause ted used cover crops, while Meadow land had fewer AM fungi present in the soil.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which land didn't have extended time for AM growth into the autumn?
