Over the course of adolescence, the amount of white matter in the brain increases linearly, while the amount of grey matter in the brain follows an inverted-U pattern. Through a process called synaptic pruning, unnecessary neuronal connections in the brain are eliminated and the amount of grey matter is pared down. However, this does not mean that the brain loses functionality; rather, it becomes more efficient due to increased myelination (insulation of axons) and the reduction of unused pathways.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Does the brain become more or less efficient as a result of synaptic pruning?
Ah, so.. more efficient

Some scholars believe that Modern Orthodoxy arose from the religious and social realities of Western European Jewry. While most Jews consider Modern Orthodoxy traditional today, some (the hareidi and hasidic groups) within the Orthodox community consider some elements to be of questionable validity. The neo-Orthodox movement holds that Hirsch's views are not accurately followed by Modern Orthodoxy. [See Torah im Derech Eretz and Torah Umadda "Relationship with Torah im Derech Eretz" for a more extensive listing.]
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is not considered traditional today by most Jews?
Ah, so.. unanswerable

The U.S. Social Security Administration (SSA), which oversees the world's largest administrative judicial system under its Office of Disability Adjudication and Review (ODAR), has made extensive use of videoconferencing to conduct hearings at remote locations. In Fiscal Year (FY) 2009, the U.S. Social Security Administration (SSA) conducted 86,320 videoconferenced hearings, a 55% increase over FY 2008. In August 2010, the SSA opened its fifth and largest videoconferencing-only National Hearing Center (NHC), in St. Louis, Missouri. This continues the SSA's effort to use video hearings as a means to clear its substantial hearing backlog. Since 2007, the SSA has also established NHCs in Albuquerque, New Mexico, Baltimore, Maryland, Falls Church, Virginia, and Chicago, Illinois.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did the SSA open its largest videoconferencing-only center?
Ah, so..
August 2010
