Problem: Sexual orientation:

Known as the fraternal birth order (FBO) effect, this theory has been backed up by strong evidence of its prenatal origin, although no evidence thus far has linked it to an exact prenatal mechanism. However, research suggests that this may be of immunological origin, caused by a maternal immune reaction against a substance crucial to male fetal development during pregnancy, which becomes increasingly likely after every male gestation. As a result of this immune effect, alterations in later-born males' prenatal development have been thought to occur. This process, known as the maternal immunization hypothesis (MIH), would begin when cells from a male fetus enter the mother's circulation during pregnancy or while giving birth. These Y-linked proteins would not be recognized in the mother's immune system because she is female, causing her to develop antibodies which would travel through the placental barrier into the fetal compartment. From here, the anti-male bodies would then cross the blood/brain barrier (BBB) of the developing fetal brain, altering sex-dimorphic brain structures relative to sexual orientation, causing the exposed son to be more attracted to men over women.

What does BBB stand for?
---
A: blood/brain barrier


Problem: Serious financial damage has been caused by security breaches, but because there is no standard model for estimating the cost of an incident, the only data available is that which is made public by the organizations involved. "Several computer security consulting firms produce estimates of total worldwide losses attributable to virus and worm attacks and to hostile digital acts in general. The 2003 loss estimates by these firms range from $13 billion (worms and viruses only) to $226 billion (for all forms of covert attacks). The reliability of these estimates is often challenged; the underlying methodology is basically anecdotal."
What is the underlying methodology of finding worldwide estimates for losses fur to security breaches?
---
Answer: basically anecdotal


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Spring 1989 saw the people of the Soviet Union exercising a democratic choice, albeit limited, for the first time since 1917, when they elected the new Congress of People's Deputies. Just as important was the uncensored live TV coverage of the legislature's deliberations, where people witnessed the previously feared Communist leadership being questioned and held accountable. This example fueled a limited experiment with democracy in Poland, which quickly led to the toppling of the Communist government in Warsaw that summer – which in turn sparked uprisings that overthrew communism in the other five Warsaw Pact countries before the end of 1989, the year the Berlin Wall fell. These events showed that the people of Eastern Europe and the Soviet Union did not support Gorbachev's drive to modernize Communism; rather, they preferred to abandon it altogether.
Who was questioned on live TV?
A: Communist leadership


Context and question: Symbiosis (from Greek σύν "together" and βίωσις "living") is close and often long-term interaction between two different biological species. In 1877 Albert Bernhard Frank used the word symbiosis (which previously had been used to depict people living together in community) to describe the mutualistic relationship in lichens. In 1879, the German mycologist Heinrich Anton de Bary defined it as "the living together of unlike organisms."
What type of organism did Frank apply the term "symbiosis" to?
Answer: lichens


Question: For over 200 years, Russia had been expanding southwards across the sparsely populated "Wild Fields" toward the warm water ports of the Black Sea that did not freeze over like the handful of other ports available in the north. The goal was to promote year-round trade and a year-round navy.:11 Pursuit of this goal brought the emerging Russian state into conflict with the Ukrainian Cossacks and then with the Tatars of the Crimean Khanate and Circassians. When Russia conquered these groups and gained possession of southern Ukraine, known as New Russia during Russian imperial times, the Ottoman Empire lost its buffer zone against Russian expansion, and Russia and the Ottoman Empire fell into direct conflict. The conflict with the Ottoman Empire also presented a religious issue of importance, as Russia saw itself as the protector of Orthodox Christians, many of whom lived under Ottoman control and were treated as second-class citizens.(ch 1)
Is there an answer to this question: During the Russian imperial times, what other name was southern Ukraine known by?

Answer: New Russia


Question: The port was the point of departure for the Pilgrim Fathers aboard Mayflower in 1620. In 1912, the RMS Titanic sailed from Southampton. Four in five of the crew on board the vessel were Sotonians, with about a third of those who perished in the tragedy hailing from the city. Southampton was subsequently the home port for the transatlantic passenger services operated by Cunard with their Blue Riband liner RMS Queen Mary and her running mate RMS Queen Elizabeth. In 1938, Southampton docks also became home to the flying boats of Imperial Airways. Southampton Container Terminals first opened in 1968 and has continued to expand.
Is there an answer to this question: How many crew members out of every five on the RMS Titanic were Sotonians?

Answer:
Four
