Question: I know that the answer to the question "The past act of formally puting an end to a system, practice, or institution, such as slavery is called?" is in "Debate remained limited, and major decisions regarding the economy and defence were avoided or dealt with cursorily; the GPC largely remained "a rubber stamp" for Gaddafi's policies. On rare occasions, the GPC opposed Gaddafi's suggestions, sometimes successfully; notably, when Gaddafi called on primary schools to be abolished, believing that home schooling was healthier for children, the GPC rejected the idea. In other instances, Gaddafi pushed through laws without the GPC's support, such as when he desired to allow women into the armed forces. Gaddafi proclaimed that the People's Congresses provided for Libya's every political need, rendering other political organizations unnecessary; all non-authorized groups, including political parties, professional associations, independent trade unions and women's groups, were banned.".

Question: I know that the answer to the question "What sare the benifts of the blood brain barrir?" is in "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 blood–brain 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.".

Answer:
isolated from the bloodstream
