Problem: John, King of England:

In the aftermath of John's death William Marshal was declared the protector of the nine-year-old Henry III. The civil war continued until royalist victories at the battles of Lincoln and Dover in 1217. Louis gave up his claim to the English throne and signed the Treaty of Lambeth. The failed Magna Carta agreement was resuscitated by Marshal's administration and reissued in an edited form in 1217 as a basis for future government. Henry III continued his attempts to reclaim Normandy and Anjou until 1259, but John's continental losses and the consequent growth of Capetian power in the 13th century proved to mark a "turning point in European history".

Who was declared the protector of Henry III after John's death?
---
A: William Marshal


Problem: Another study of dogs' roles in families showed many dogs have set tasks or routines undertaken as family members, the most common of which was helping with the washing-up by licking the plates in the dishwasher, and bringing in the newspaper from the lawn. Increasingly, human family members are engaging in activities centered on the perceived needs and interests of the dog, or in which the dog is an integral partner, such as dog dancing and dog yoga.
In addition to dog dancing, what is another activity that families are doing that is centered around their pet?
---
Answer: dog yoga.


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Charleston is known for its unique culture, which blends traditional Southern U.S., English, French, and West African elements. The downtown peninsula has gained a reputation for its art, music, local cuisine, and fashion. Spoleto Festival USA, held annually in late spring, has become one of the world's major performing arts festivals. It was founded in 1977 by Pulitzer Prize-winning composer Gian Carlo Menotti, who sought to establish a counterpart to the Festival dei Due Mondi (the Festival of Two Worlds) in Spoleto, Italy.
What major award did Gian Carlo Menotti win?
A: Pulitzer Prize


Context and question: President Franklin Roosevelt ordered General Douglas MacArthur in the Philippines to formulate a Pacific defence plan with Australia in March 1942. Curtin agreed to place Australian forces under the command of MacArthur who became Supreme Commander, South West Pacific. MacArthur moved his headquarters to Melbourne in March 1942 and American troops began massing in Australia. Enemy naval activity reached Sydney in late May 1942, when Japanese midget submarines launched a daring raid on Sydney Harbour. On 8 June 1942, two Japanese submarines briefly shelled Sydney's eastern suburbs and the city of Newcastle.
How many Japanese submarines shelled Sydney on June 8, 1942?
Answer: two


Question: BYU accepted 49 percent of the 11,423 people who applied for admission in the summer term and fall semester of 2013. The average GPA for these admitted students was 3.82. U.S. News and World Report describes BYU's selectivity as being "more selective" and compares it with such universities as the University of Texas at Austin and The Ohio State University. In addition, BYU is ranked 26th in colleges with the most freshman Merit Scholars, with 88 in 2006. BYU has one of the highest percentage of accepted applicants that go on to enroll (78 percent in 2010).
Is there an answer to this question: What school accepted 49% of the 11,324 people who applied in 2013?

Answer: unanswerable


Problem: Antenna (radio):

When an electromagnetic wave strikes a plane surface such as the ground, part of the wave is transmitted into the ground and part of it is reflected, according to the Fresnel coefficients. If the ground is a very good conductor then almost all of the wave is reflected (180° out of phase), whereas a ground modeled as a (lossy) dielectric can absorb a large amount of the wave's power. The power remaining in the reflected wave, and the phase shift upon reflection, strongly depend on the wave's angle of incidence and polarization. The dielectric constant and conductivity (or simply the complex dielectric constant) is dependent on the soil type and is a function of frequency.

what is reflected and transmitted into the ground when a plane surface is struck?
---
A:
electromagnetic wave
