Please answer this: Question: "What is vulnerable to numerous diseases?" Context: "Another approach to brain function is to examine the consequences of damage to specific brain areas. Even though it is protected by the skull and meninges, surrounded by cerebrospinal fluid, and isolated from the bloodstream by the bloodbrain barrier, the delicate nature of the brain makes it vulnerable to numerous diseases and several types of damage. In humans, the effects of strokes and other types of brain damage have been a key source of information about brain function. Because there is no ability to experimentally control the nature of the damage, however, this information is often difficult to interpret. In animal studies, most commonly involving rats, it is possible to use electrodes or locally injected chemicals to produce precise patterns of damage and then examine the consequences for behavior."

Problem: Question: "Why did Universal's former parent company let go of them?" Context: "Matsushita provided a cash infusion, but the clash of cultures was too great to overcome, and five years later Matsushita sold an 80% stake in MCA/Universal to Canadian drinks distributor Seagram for $5.7 billion.

Problem: Given the question: Question: "What material did airport designers use to build the longer runways required by the increase in jet aircraft traffic?" Context: "Airport construction boomed during the 1960s with the increase in jet aircraft traffic. Runways were extended out to 3,000 m (9,800 ft). The fields were constructed out of reinforced concrete using a slip-form machine that produces a continual slab with no disruptions along the length. The early 1960s also saw the introduction of jet bridge systems to modern airport terminals, an innovation which eliminated outdoor passenger boarding. These systems became commonplace in the United States by the 1970s." Answer:

To the resulting lack of intelligence at the top can be ascribed all the inexcusable defects of French military policy."" Answer:
----
