The problem: Answer a question about this article:
Working closely in conjunction with the definition of the Near East provided by the State Department is the Near East South Asia Center for Strategic Studies (NESA), an educational institution of the United States Department of Defense. It teaches courses and holds seminars and workshops for government officials and military officers who will work or are working within its region. As the name indicates, that region is a combination of State Department regions; however, NESA is careful to identify the State Department region. As its Near East is not different from the State Department's it does not appear in the table. Its name, however, is not entirely accurate. For example, its region includes Mauritania, a member of the State Department's Africa (Sub-Sahara).
What does NESA Teach?
****
The answer: It teaches courses and holds seminars and workshops

Question: Read this and answer the question

The phase of reflection of electromagnetic waves depends on the polarization of the incident wave. Given the larger refractive index of the ground (typically n=2) compared to air (n=1), the phase of horizontally polarized radiation is reversed upon reflection (a phase shift of radians or 180). On the other hand, the vertical component of the wave's electric field is reflected at grazing angles of incidence approximately in phase. These phase shifts apply as well to a ground modelled as a good electrical conductor.

What is the refractive index of the ground?
Answer: n=2

Problem: In 1918 Whitehead's academic responsibilities began to seriously expand as he accepted a number of high administrative positions within the University of London system, of which Imperial College London was a member at the time. He was elected Dean of the Faculty of Science at the University of London in late 1918 (a post he held for four years), a member of the University of London's Senate in 1919, and chairman of the Senate's Academic (leadership) Council in 1920, a post which he held until he departed for America in 1924. Whitehead was able to exert his newfound influence to successfully lobby for a new history of science department, help establish a Bachelor of Science degree (previously only Bachelor of Arts degrees had been offered), and make the school more accessible to less wealthy students.
What was he elected at the University of London?
The answer is the following: Dean of the Faculty of Science

Input: Article: Following the start of the Arab Spring in 2011, Gaddafi spoke out in favour of Tunisian President Zine El Abidine Ben Ali, then threatened by the Tunisian Revolution. He suggested that Tunisia's people would be satisfied if Ben Ali introduced a Jamahiriyah system there. Fearing domestic protest, Libya's government implemented preventative measures, reducing food prices, purging the army leadership of potential defectors and releasing several Islamist prisoners. They proved ineffective, and on 17 February 2011, major protests broke out against Gaddafi's government. Unlike Tunisia or Egypt, Libya was largely religiously homogenous and had no strong Islamist movement, but there was widespread dissatisfaction with the corruption and entrenched systems of patronage, while unemployment had reached around 30%.

Now answer this question: On what date in 2011 did protests begin in Libya?

Output:
17 February
