Question: The central Sahara is estimated to include five hundred species of plants, which is extremely low considering the huge extent of the area. Plants such as acacia trees, palms, succulents, spiny shrubs, and grasses have adapted to the arid conditions, by growing lower to avoid water loss by strong winds, by storing water in their thick stems to use it in dry periods, by having long roots that travel horizontally to reach the maximum area of water and to find any surface moisture and by having small thick leaves or needles to prevent water loss by evapo-transpiration. Plant leaves may dry out totally and then recover.
Is there an answer to this question: What do plants do in order to avoid water loss?

Answer: growing lower

Question: Peruvian Carnival incorporates elements of violence and reflects the urban violence in Peruvian society following the internal conflict in Peru. Traditionally, Peruvian Andean festivities were held on this period every year because it is the rainy season. It was already violent during the 19th century, but the government limited the practice. During the early 20th century it consisted partying and parading, while in the second half of the 20th century it acquired violent characteristics that continued. It was banned, first from the streets in 1958 and altogether in 1959 by the Prado government. It consisted basically of water battles in a traditional way,[clarification needed] while in later years it included playing with dirty water, mud, oil and colorants -and also including fighting and sometimes looting private property and sexual assaults on women. It has become an excuse for criminal gangs to rob people while pretending to celebrate. As of 2010, it had become so violent that the government imposed penalties of up to eight years in prison for violence during the games (the games themselves are not forbidden, but using violence during the games or coercing others to participate is).
Is there an answer to this question: When did the festivities acquire their violent tendencies?

Answer: second half of the 20th century
