Problem: In Lithuania Propria and in Samogitia prior to the creation of the Kingdom of Lithuania by Mindaugas, nobles were named die beste leuten in sources that were written in German language. In the Lithuanian language nobles were named ponai. The higher nobility were named 'kunigai' or 'kunigaikščiai' (dukes)—i.e., loanword from Scandinavic konung. They were the established local leaders and warlords. During the development of the state they gradually became subordinated to higher dukes, and later to the King of Lithuania. Because of expansion of Lithuanian duchy into lands of Ruthenia in the mid of 14th century a new term appeared to denominate nobility bajorai—from Ruthenian (modern Ukrainian and Belarusian languages) бояре. This word to this day is used in Lithuanian language to name nobility, not only for own, but also for nobility of other countries.
The kunigai were subordinate to who?
The answer is the following: King of Lithuania.

Problem: From the beginning of 2014, Madonna began to make multiple media appearances. She appeared at the 56th Annual Grammy Awards in January 2014, performing "Open Your Heart" alongside rappers Macklemore & Ryan Lewis and singer Mary Lambert, who sang their single "Same Love", as 33 couples were wed onstage, officiated by Queen Latifah. Days later, she joined singer Miley Cyrus on her MTV Unplugged special, singing a mash-up of "Don't Tell Me" and Cyrus' single "We Can't Stop" (2013). She also extended her business ventures and in February 2014 the singer premiered MDNA Skin, a range of skin care products, in Tokyo, Japan. After visiting her hometown of Detroit during May 2014, Madonna decided to contribute funds to three of the city's organizations, to help eliminate poverty from there. The singer released a statement saying that she was inspired by their work, adding that "it was obvious to me that I had to get involved and be part of the solution to help Detroit recover".
What song did Madonna sing at the ceremony?
The answer is the following: Open Your Heart

Problem: Temporal measurement has occupied scientists and technologists, and was a prime motivation in navigation and astronomy. Periodic events and periodic motion have long served as standards for units of time. Examples include the apparent motion of the sun across the sky, the phases of the moon, the swing of a pendulum, and the beat of a heart. Currently, the international unit of time, the second, is defined by measuring the electronic transition frequency of caesium atoms (see below). Time is also of significant social importance, having economic value ("time is money") as well as personal value, due to an awareness of the limited time in each day and in human life spans.
The electronic transition frequency of which element defines the second?
The answer is the following: caesium atoms

Problem: New sequencing technologies, such as massive parallel sequencing have also opened up the prospect of personal genome sequencing as a diagnostic tool, as pioneered by Manteia Predictive Medicine. A major step toward that goal was the completion in 2007 of the full genome of James D. Watson, one of the co-discoverers of the structure of DNA.
What is Watson famous for helping discover?
The answer is the following:
the structure of DNA
