Article: The Central Bank of Liberia is responsible for printing and maintaining the Liberian dollar, which is the primary form of currency in Liberia. Liberia is one of the world's poorest countries, with a formal employment rate of 15%. GDP per capita peaked in 1980 at US$496, when it was comparable to Egypt's (at the time). In 2011, the country's nominal GDP was US$1.154 billion, while nominal GDP per capita stood at US$297, the third-lowest in the world. Historically, the Liberian economy has depended heavily on foreign aid, foreign direct investment and exports of natural resources such as iron ore, rubber and timber.

Question: The GDP peaked in 1980 at what amount?
Ans: US$496


Here is a question about this article: In the 1970s, the Bronx was plagued by a wave of arson. The burning of buildings was predominantly in the poorest communities, like the South Bronx. The most common explanation of what occurred was that landlords decided to burn their low property-value buildings and take the insurance money as it was more lucrative to get insurance money than to refurbish or sell a building in a severely distressed area. The Bronx became identified with a high rate of poverty and unemployment, which was mainly a persistent problem in the South Bronx.
What is the answer to this question: What crime was common in the Bronx in the 1970s?
****
So... arson


The problem: Answer a question about this article:
According to reciprocity, the efficiency of an antenna used as a receiving antenna is identical to the efficiency as defined above. The power that an antenna will deliver to a receiver (with a proper impedance match) is reduced by the same amount. In some receiving applications, the very inefficient antennas may have little impact on performance. At low frequencies, for example, atmospheric or man-made noise can mask antenna inefficiency. For example, CCIR Rep. 258-3 indicates man-made noise in a residential setting at 40 MHz is about 28 dB above the thermal noise floor. Consequently, an antenna with a 20 dB loss (due to inefficiency) would have little impact on system noise performance. The loss within the antenna will affect the intended signal and the noise/interference identically, leading to no reduction in signal to noise ratio (SNR).
What is SNR?
****
The answer: signal to noise ratio


Problem: Please answer a question about the following article about Egypt:
Egypt's most prominent multinational companies are the Orascom Group and Raya Contact Center. The information technology (IT) sector has expanded rapidly in the past few years, with many start-ups selling outsourcing services to North America and Europe, operating with companies such as Microsoft, Oracle and other major corporations, as well as many small and medium size enterprises. Some of these companies are the Xceed Contact Center, Raya, E Group Connections and C3. The IT sector has been stimulated by new Egyptian entrepreneurs with government encouragement.[citation needed]
What are Egypt's 2 most prominent multinational compnaies?
A: Orascom Group and Raya Contact Center


Question: Read this and answer the question

Treaties can be loosely compared to contracts: both are means of willing parties assuming obligations among themselves, and a party to either that fails to live up to their obligations can be held liable under international law.

What must a party to a treaty do to prevent being held liable under international law?
Answer: live up to their obligations


Leakage is equivalent to a resistor in parallel with the capacitor. Constant exposure to heat can cause dielectric breakdown and excessive leakage, a problem often seen in older vacuum tube circuits, particularly where oiled paper and foil capacitors were used. In many vacuum tube circuits, interstage coupling capacitors are used to conduct a varying signal from the plate of one tube to the grid circuit of the next stage. A leaky capacitor can cause the grid circuit voltage to be raised from its normal bias setting, causing excessive current or signal distortion in the downstream tube. In power amplifiers this can cause the plates to glow red, or current limiting resistors to overheat, even fail. Similar considerations apply to component fabricated solid-state (transistor) amplifiers, but owing to lower heat production and the use of modern polyester dielectric barriers this once-common problem has become relatively rare.
With what value is a resistor in parallel with a capacitor equal to?
Leakage
