Question: Question: Which country that Austria has a border barrier with has the highest population? Passage:Austrian border barriers are border barriers and migration management facilities constructed by Austria between November 2015 and January 2016 on its border with Slovenia and in 2016 on its border with Italy, as a response to European migrant crisis. They are located on internal European Union borders, since Austria, Italy, and Slovenia are members of the EU and the free travel Schengen Area with a common visa policy. The barrier on the Slovenian border is several kilometres long, located near the busiest border crossing, Spielfeld-Šentilj, and includes police facilities for screening and processing migrants. Another migration management facility with barriers located on Austria's Italian border near Brenner, South Tyrol was constructed in 2016.

Question: Question: Was the Social Democratic Party around when Knochel was conscripted into the Imperial Army? Passage:Wilhelm Knöchel was born into a Social Democratic working class family in Offenbach, a short distance upriver from Frankfurt. He qualified and worked as a factory machine operator ("Dreher"). In 1917 he was conscripted into the Imperial Army, shortly after which he was badly wounded. There are also references to his having worked as a mines maintenance engineer ("Grubenschlosser"). In 1919, with Germany affected by acute economic hardship and, especially in the cities, a succession of revolutionary uprisings, Knöchel joined the Social Democratic Party ("Sozialdemokratische Partei Deutschlands" / SPD). By 1920 he had relocated in search of work to the industrially vital and internationally critical Ruhr region. Sources differ over whether it was in 1920 or 1923 that he switched to the recently created Communist Party. Between 1924 and 1930 he was a member of the party leadership team for the Dortmund region ("...des Unterbezirk Dortmund"). In 1930, following the death of his first wife, he returned to Offenbach, where it was arranged that his daughter should be brought up by relatives. Knöchel was now employed as a party official.

Question: Question: Of the two indicator species of trees for the lower montane forest, which grows taller? Passage:Beginning near the elevation, the hot, dry summers and cool, moist winters of the Mediterranean climate give rise to the lower montane forest zone. This zone is also known as the yellow pine forest zone. The accumulation of several feet of snow during the winter is not uncommon and can stay on the ground for several months. The diversity of tree species found in this zone make this a beautiful and interesting forest to explore. The indicator species for the lower montane forest are the ponderosa pine and the Jeffrey pine: the ponderosa pine generally occurs on the west side of the Sierra, while the Jeffrey pine occurs on the east. The lower montane forests also include trees such as California black oak, sugar pine, incense-cedar, and white fir. Animals that may be found in this zone include the dark-eyed junco, mountain chickadee, western gray squirrel, mule deer, and American black bear.
