Input: Read this: In January 1964, Nasser called for an Arab League summit in Cairo to establish a unified Arab response against Israel's plans to divert the Jordan River's waters for economic purposes, which Syria and Jordan deemed an act of war. Nasser blamed Arab divisions for what he deemed "the disastrous situation". He discouraged Syria and Palestinian guerrillas from provoking the Israelis, conceding that he had no plans for war with Israel. During the summit, Nasser developed cordial relations with King Hussein, and ties were mended with the rulers of Saudi Arabia, Syria, and Morocco. In May, Nasser moved to formally share his leadership position over the Palestine issue by initiating the creation of the Palestine Liberation Organization (PLO). In practice, Nasser used the PLO to wield control over the Palestinian fedayeen. Its head was to be Ahmad Shukeiri, Nasser's personal nominee.
Question: What organization was formed as a result of the talks?

Output: Palestine Liberation Organization


QUES: The final decades of the 20th century have seen the rise of a new interdisciplinary approach to studying human psychology, known collectively as cognitive science. Cognitive science again considers the mind as a subject for investigation, using the tools of psychology, linguistics, computer science, philosophy, and neurobiology. New methods of visualizing the activity of the brain, such as PET scans and CAT scans, began to exert their influence as well, leading some researchers to investigate the mind by investigating the brain, rather than cognition. These new forms of investigation assume that a wide understanding of the human mind is possible, and that such an understanding may be applied to other research domains, such as artificial intelligence.

What is investigated in cognitive science?
What is the answer?
ANS: the mind


QUES: In April 2013, the Infectious Disease Society of America (IDSA) reported that the weak antibiotic pipeline does not match bacteria's increasing ability to develop resistance. Since 2009, only 2 new antibiotics were approved in the United States. The number of new antibiotics approved for marketing per year declines continuously. The report identified seven antibiotics against the Gram-negative bacilli (GNB) currently in phase 2 or phase 3 clinical trials. However, these drugs do not address the entire spectrum of resistance of GNB. Some of these antibiotics are combination of existent treatments:
What year did the Infectious Disease Society of America say that production of new antibiotics does not keep up with resistance?

ANS: 2013


As one of their first acts after end of the War of the Castilian Succession in 1479, Ferdinand and Isabella established the centrally organized and efficient Holy Brotherhood (Santa Hermandad) as a national police force. They adapted an existing brotherhood to the purpose of a general police acting under officials appointed by themselves, and endowed with great powers of summary jurisdiction even in capital cases. The original brotherhoods continued to serve as modest local police-units until their final suppression in 1835.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who formed Spain's last national police force?
Ah, so.. unanswerable
