Question: An unauthorized user gaining physical access to a computer is most likely able to directly download data from it. They may also compromise security by making operating system modifications, installing software worms, keyloggers, or covert listening devices. Even when the system is protected by standard security measures, these may be able to be by passed by booting another operating system or tool from a CD-ROM or other bootable media. Disk encryption and Trusted Platform Module are designed to prevent these attacks.
Try to answer this question if possible: What can an authorized user with access to a computer do?
Answer: unanswerable
Question: In DC circuits and pulsed circuits, current and voltage reversal are affected by the damping of the system. Voltage reversal is encountered in RLC circuits that are under-damped. The current and voltage reverse direction, forming a harmonic oscillator between the inductance and capacitance. The current and voltage will tend to oscillate and may reverse direction several times, with each peak being lower than the previous, until the system reaches an equilibrium. This is often referred to as ringing. In comparison, critically damped or over-damped systems usually do not experience a voltage reversal. Reversal is also encountered in AC circuits, where the peak current will be equal in each direction.
Try to answer this question if possible: What is one type of circuit in which voltage and current reversal are affected by damping?
Answer: DC circuits
Question: A study in 2007 by Mark Long, an economics professor at the University of Washington, demonstrated that the alternatives of affirmative action proved ineffective in restoring minority enrollment in public flagship universities in California, Texas, and Washington. More specifically, apparent rebounds of minority enrollment can be explained by increasing minority enrollment in high schools of those states, and the beneficiaries of class-based (not race) affirmative action would be white students. At the same time, affirmative action itself is both morally and materially costly: 52 percent of white populace (compared to 14 percent of black) thought it should be abolished, implying white distaste of using racial identity, and full-file review is expected to cost the universities an additional $1.5 million to $2 million per year, excluding possible cost of litigation.
Try to answer this question if possible: What percentage of the black population thought affirmative action should not be abolished?
Answer: unanswerable
Question: World War II (1939-1945) devastated the country's economy, but the high levels of economic growth that followed from 1950 to 1980 have been called the Greek economic miracle. From 2000 Greece saw high levels of GDP growth above the Eurozone average, peaking at 5.8% in 2003 and 5.7% in 2006. The subsequent Great Recession and Greek government-debt crisis, a central focus of the wider European debt crisis, plunged the economy into a sharp downturn, with real GDP growth rates of 0.3% in 2008, 4.3% in 2009, 5.5% in 2010, 9.1% in 2011, 7.3% in 2012 and 3.2% in 2013. In 2011, the country's public debt reached 356 billion (172% of nominal GDP). After negotiating the biggest debt restructuring in history with the private sector, Greece reduced its sovereign debt burden to 280 billion (137% of GDP) in the first quarter of 2012. Greece achieved a real GDP growth rate of 0.7% in 2014 after 6 years of economic decline, but fell back into recession in 2015.
