Input: Read this: The oak forests generally lack the diverse small tree, shrub and herb layers of mesic forests. Shrubs are generally ericaceous, and include the evergreen mountain laurel (Kalmia latifolia), various species of blueberries (Vaccinium spp.), black huckleberry (Gaylussacia baccata), a number of deciduous rhododendrons (azaleas), and smaller heaths such as teaberry (Gaultheria procumbens) and trailing arbutus (Epigaea repens ). The evergreen great rhododendron (Rhododendron maximum) is characteristic of moist stream valleys. These occurrences are in line with the prevailing acidic character of most oak forest soils. In contrast, the much rarer chinquapin oak (Quercus muehlenbergii) demands alkaline soils and generally grows where limestone rock is near the surface. Hence no ericaceous shrubs are associated with it.
Question: What is rarely found near moist areas?

Output: unanswerable


Input: Read this: Archaeologist Louis Binford criticised the idea that early hominids and early humans were hunters. On the basis of the analysis of the skeletal remains of the consumed animals, he concluded that hominids and early humans were mostly scavengers, not hunters, and this idea is popular among some archaeologists and paleoanthropologists. Robert Blumenschine proposed the idea of confrontational scavenging, which involves challenging and scaring off other predators after they have made a kill, which he suggests could have been the leading method of obtaining protein-rich meat by early humans.
Question: What does confrontational scavenging involve doing to other predators after they've made a kill?

Output: challenging and scaring off


Input: Read this: In September 1975, Gaddafi purged the army, arresting around 200 senior officers, and in October he founded the clandestine Office for the Security of the Revolution. In 1976, student demonstrations broke out in Tripoli and Benghazi, and were attacked by police and Gaddafist students. The RCC responded with mass arrests, and introduced compulsory national service for young people. Dissent also arose from conservative clerics and the Muslim Brotherhood, who were persecuted as anti-revolutionary. In January 1977, two dissenting students and a number of army officers were publicly hanged; Amnesty International condemned it as the first time in Gaddafist Libya that dissenters had been executed for purely political crimes.
Question: Who criticized the political execution of students and military officers that occurred in January 1977?

Output: Amnesty International


Input: Read this: A large indoor shopping centre Hoog Catharijne (nl) is located between Utrecht Centraal railway station and the city centre. The corridors are treated as public places like streets, and the route between the station and the city centre is open all night. In 20 years from 2004, parts of Hoog Catharijne will be redeveloped as part of the renovation of the larger station area. Parts of the city's network of canals, which were filled to create the shopping center and central station area, will be recreated. The Jaarbeurs, one of the largest convention centres in the Netherlands, is located at the west side of the central railway station.
Question: how are the shopping center corridors treated 

Output:
The corridors are treated as public places like streets, and the route between the station and the city centre is open all night
