Economic sanctions against Iran, such as the embargo against Iranian crude oil, have affected the economy. Sanctions have led to a steep fall in the value of the rial, and as of April 2013 one US dollar is worth 36,000 rial, compared with 16,000 in early 2012. Following a successful implementation of the 2015 nuclear and sanctions relief deal, the resulting benefits might not be distributed evenly across the Iranian economy as political elites such as the Islamic Revolutionary Guard Corps have garnered more resources and economic interests.
How much was 1 US Dollar worth in Iranian Rials in early 2012?
16,000

Input: Antenna (radio)
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?
Output: signal to noise ratio

Input: Article: As a defining aspect of what it means to be human, culture is a central concept in anthropology, encompassing the range of phenomena that are transmitted through social learning in human societies. The word is used in a general sense as the evolved ability to categorize and represent experiences with symbols and to act imaginatively and creatively. This ability arose with the evolution of behavioral modernity in humans around 50,000 years ago.[citation needed] This capacity is often thought to be unique to humans, although some other species have demonstrated similar, though much less complex abilities for social learning. It is also used to denote the complex networks of practices and accumulated knowledge and ideas that is transmitted through social interaction and exist in specific human groups, or cultures, using the plural form. Some aspects of human behavior, such as language, social practices such as kinship, gender and marriage, expressive forms such as art, music, dance, ritual, religion, and technologies such as cooking, shelter, clothing are said to be cultural universals, found in all human societies. The concept material culture covers the physical expressions of culture, such as technology, architecture and art, whereas the immaterial aspects of culture such as principles of social organization (including, practices of political organization and social institutions), mythology, philosophy, literature (both written and oral), and science make up the intangible cultural heritage of a society.

Now answer this question: What does the term "concept material culture" cover?

Output: technology, architecture and art

Article: Korea was ruled by Japan from 1910 until the closing days of World War II. In August 1945, the Soviet Union declared war on Japan andby agreement with the United Statesoccupied Korea north of the 38th parallel. U.S. forces subsequently occupied the south and Japan surrendered. By 1948, two separate governments had been set up. Both governments claimed to be the legitimate government of Korea, and neither side accepted the border as permanent. The conflict escalated into open warfare when North Korean forcessupported by the Soviet Union and Chinainvaded South Korea on 25 June 1950. On that day, the United Nations Security Council recognized this North Korean act as invasion and called for an immediate ceasefire. On 27 June, the Security Council adopted S/RES/83: Complaint of aggression upon the Republic of Korea and decided the formation and dispatch of the UN Forces in Korea. Twenty-one countries of the United Nations eventually contributed to the defense of South Korea, with the United States providing 88% of the UN's military personnel.

Question: Who occupied Korea south of the 38th parallel?
Ans: U.S. forces

Here is a question about this article: Excavations in and near Agordat in central Eritrea yielded the remains of an ancient pre-Aksumite civilization known as the Gash Group. Ceramics were discovered that were related to those of the C-Group (Temehu) pastoral culture, which inhabited the Nile Valley between 25001500 BC. Some sources dating back to 3500 BC. Shards akin to those of the Kerma culture, another community that flourished in the Nile Valley around the same period, were also found at other local archaeological sites in the Barka valley belonging to the Gash Group. According to Peter Behrens (1981) and Marianne Bechaus-Gerst (2000), linguistic evidence indicates that the C-Group and Kerma peoples spoke Afroasiatic languages of the Berber and Cushitic branches, respectively.
What is the answer to this question: When did the C-Group inhabit the Nile Valley?
****
So... between 25001500 BC

Article: After the U.S. accused Libya of orchestrating the 1986 Berlin discotheque bombing, in which two American soldiers died, Reagan decided to retaliate militarily. The Central Intelligence Agency were critical of the move, believing that Syria were a greater threat and that an attack would strengthen Gaddafi's reputation; however Libya was recognised as a "soft target." Reagan was supported by the U.K. but opposed by other European allies, who argued that it would contravene international law. In Operation El Dorado Canyon, orchestrated on 15 April 1986, U.S. military planes launched a series of air-strikes on Libya, bombing military installations in various parts of the country, killing around 100 Libyans, including several civilians. One of the targets had been Gaddafi's home. Himself unharmed, two of Gaddafi's sons were injured, and he claimed that his four-year-old adopted daughter Hanna was killed, although her existence has since been questioned. In the immediate aftermath, Gaddafi retreated to the desert to meditate, while there were sporadic clashes between Gaddafists and army officers who wanted to overthrow the government. Although the U.S. was condemned internationally, Reagan received a popularity boost at home. Publicly lambasting U.S. imperialism, Gaddafi's reputation as an anti-imperialist was strengthened both domestically and across the Arab world, and in June 1986, he ordered the names of the month to be changed in Libya.

Question: How many Americans died in the Berlin disco bombing of 1986?
Ans:
two
