Problem: Seven Years%27 War:

By this point Frederick was increasingly concerned by the Russian advance from the east and marched to counter it. Just east of the Oder in Brandenburg-Neumark, at the Battle of Zorndorf (now Sarbinowo, Poland), a Prussian army of 35,000 men under Frederick on Aug. 25, 1758, fought a Russian army of 43,000 commanded by Count William Fermor. Both sides suffered heavy casualties the Prussians 12,800, the Russians 18,000 but the Russians withdrew, and Frederick claimed victory. In the undecided Battle of Tornow on 25 September, a Swedish army repulsed six assaults by a Prussian army but did not push on Berlin following the Battle of Fehrbellin.

Which army withdrew?

A: the Russians withdrew

Problem: Many modern specialty matches have been devised, with unique winning conditions. The most common of these is the ladder match. In the basic ladder match, the wrestlers or teams of wrestlers must climb a ladder to obtain a prize that is hoisted above the ring. The key to winning this match is that the wrestler or team of wrestlers must try to incapacitate each other long enough for one wrestler to climb the ladder and secure that prize for their team. As a result, the ladder can be used as a weapon. The prizes include but are not limited to any given championship belt (the traditional prize), a document granting the winner the right to a future title shot, or any document that matters to the wrestlers involved in the match (such as one granting the winner a cash prize). Another common specialty match is known as the battle royal. In a battle royal, all the wrestlers enter the ring to the point that there are 20-30 wrestlers in the ring at one time. When the match begins, the simple objective is to throw the opponent over the top rope and out of the ring with both feet on the floor in order to eliminate that opponent. The last wrestler standing is declared the winner. A variant on this type of match is the WWE's Royal Rumble where two wrestlers enter the ring to start the match and other wrestlers follow in 90 second intervals (previously 2 minutes) until 30-40 wrestlers have entered the ring. All other rules stay the same. For more match types, see Professional wrestling match types.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The expression of genes encoded in DNA begins by transcribing the gene into RNA, a second type of nucleic acid that is very similar to DNA, but whose monomers contain the sugar ribose rather than deoxyribose. RNA also contains the base uracil in place of thymine. RNA molecules are less stable than DNA and are typically single-stranded. Genes that encode proteins are composed of a series of three-nucleotide sequences called codons, which serve as the "words" in the genetic "language". The genetic code specifies the correspondence during protein translation between codons and amino acids. The genetic code is nearly the same for all known organisms.:4.1
How does the expression of genes encoded in DNA begin?
A: by transcribing the gene into RNA

Context and question: Roncalli was elected pope on 28 October 1958 at age 76 after 11 ballots. His selection was unexpected, and Roncalli himself had come to Rome with a return train ticket to Venice. He was the first pope to take the pontifical name of "John" upon election in more than 500 years, and his choice settled the complicated question of official numbering attached to this papal name due to the antipope of this name. Pope John XXIII surprised those who expected him to be a caretaker pope by calling the historic Second Vatican Council (196265), the first session opening on 11 October 1962. His passionate views on equality were summed up in his famous statement, "We were all made in God's image, and thus, we are all Godly alike." John XXIII made many passionate speeches during his pontificate, one of which was on the day that he opened the Second Vatican Council in the middle of the night to the crowd gathered in St. Peter's Square: "Dear children, returning home, you will find children: give your children a hug and say: This is a hug from the Pope!"
How old was Roncalli when elected pope?
Answer: 76

Question: 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.
Is there an answer to this question: What type of soils do most mesic forests have?

Answer: unanswerable

Problem: Dog:

The health benefits of dogs can result from contact with dogs in general, and not solely from having dogs as pets. For example, when in the presence of a pet dog, people show reductions in cardiovascular, behavioral, and psychological indicators of anxiety. Other health benefits are gained from exposure to immune-stimulating microorganisms, which, according to the hygiene hypothesis, can protect against allergies and autoimmune diseases. The benefits of contact with a dog also include social support, as dogs are able to not only provide companionship and social support themselves, but also to act as facilitators of social interactions between humans. One study indicated that wheelchair users experience more positive social interactions with strangers when they are accompanied by a dog than when they are not. In 2015, a study found that pet owners were significantly more likely to get to know people in their neighborhood than non-pet owners.

What do humans get exposed to with pets that may help them not get sick?
---
A:
immune-stimulating microorganisms
