The problem: Answer a question about this article:
Plants uptake essential elements from the soil through their roots and from the air (consisting of mainly nitrogen and oxygen) through their leaves. Green plants obtain their carbohydrate supply from the carbon dioxide in the air by the process of photosynthesis. Carbon and oxygen are absorbed from the air, while other nutrients are absorbed from the soil. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps. These hydrogen ions displace cations attached to negatively charged soil particles so that the cations are available for uptake by the root. In the leaves, stomata open to take in carbon dioxide and expel oxygen. The carbon dioxide molecules are used as the carbon source in photosynthesis.
How do plants absorb essential elements that are present in the soil?
****
The answer: through their roots

In the 19th century, southern and central European sport hunters often pursued game only for a trophy, usually the head or pelt of an animal, which was then displayed as a sign of prowess. The rest of the animal was typically discarded. Some cultures, however, disapprove of such waste. In Nordic countries, hunting for trophies wasand still isfrowned upon. Hunting in North America in the 19th century was done primarily as a way to supplement food supplies, although it is now undertaken mainly for sport.[citation needed] The safari method of hunting was a development of sport hunting that saw elaborate travel in Africa, India and other places in pursuit of trophies. In modern times, trophy hunting persists and is a significant industry in some areas.[citation needed]
What was hunting in North American in the 19th century used to supplement?
****
The answer: food supplies

Due to many centuries of intensive settlement, most of the area is shaped by human influence. The original natural vegetation of Thuringia is forest with beech as its predominant species, as can still be found in the Hainich mountains today. In the uplands, a mixture of beech and spruce would be natural. However, most of the plains have been cleared and are in intensive agricultural use while most of the forests are planted with spruce and pine. Since 1990, Thuringia's forests have been managed aiming for a more natural and tough vegetation more resilient to climate change as well as diseases and vermin. In comparison to the forest, agriculture is still quite conventional and dominated by large structures and monocultures. Problems here are caused especially by increasingly prolonged dry periods during the summer months.
What is the original natural vegetation of Thuringia?
****
The answer: forest with beech as its predominant species

The problem: Answer a question about this article:
The baptism of Jesus and his crucifixion are considered to be two historically certain facts about Jesus. James Dunn states that these "two facts in the life of Jesus command almost universal assent" and "rank so high on the 'almost impossible to doubt or deny' scale of historical facts" that they are often the starting points for the study of the historical Jesus. Bart Ehrman states that the crucifixion of Jesus on the orders of Pontius Pilate is the most certain element about him. John Dominic Crossan states that the crucifixion of Jesus is as certain as any historical fact can be. Eddy and Boyd state that it is now "firmly established" that there is non-Christian confirmation of the crucifixion of Jesus. Craig Blomberg states that most scholars in the third quest for the historical Jesus consider the crucifixion indisputable. Christopher M. Tuckett states that, although the exact reasons for the death of Jesus are hard to determine, one of the indisputable facts about him is that he was crucified.
What is one of the historical certain facts about Jesus?
****
The answer:
baptism of Jesus
