The problem: Answer a question about this article:
Emerging British acts included Free, who released their signature song "All Right Now" (1970), which has received extensive radio airplay in both the UK and US. After the breakup of the band in 1973, vocalist Paul Rodgers joined supergroup Bad Company, whose eponymous first album (1974) was an international hit. The mixture of hard rock and progressive rock, evident in the works of Deep Purple, was pursued more directly by bands like Uriah Heep and Argent. Scottish band Nazareth released their self-titled debut album in 1971, producing a blend of hard rock and pop that would culminate in their best selling, Hair of the Dog (1975), which contained the proto-power ballad "Love Hurts". Having enjoyed some national success in the early 1970s, Queen, after the release of Sheer Heart Attack (1974) and A Night at the Opera (1975), gained international recognition with a sound that used layered vocals and guitars and mixed hard rock with heavy metal, progressive rock, and even opera. The latter featured the single "Bohemian Rhapsody", which stayed at number one in the UK charts for nine weeks.
What was Queen's massive 1975 hit single called?
****
The answer: "Bohemian Rhapsody"

Problem: Please answer a question about the following article about Florida:
Extended systems of underwater caves, sinkholes and springs are found throughout the state and supply most of the water used by residents. The limestone is topped with sandy soils deposited as ancient beaches over millions of years as global sea levels rose and fell. During the last glacial period, lower sea levels and a drier climate revealed a much wider peninsula, largely savanna. The Everglades, an enormously wide, slow-flowing river encompasses the southern tip of the peninsula. Sinkhole damage claims on property in the state exceeded a total of $2 billion from 2006 through 2010.
What did the last glacial period provide
A: lower sea levels and a drier climate revealed a much wider peninsula, largely savanna.

In the Battle of Cowan's Ford, Cornwallis met resistance along the banks of the Catawba River at Cowan's Ford on February 1, 1781, in an attempt to engage General Morgan's forces during a tactical withdrawal. Morgan had moved to the northern part of the state to combine with General Greene's newly recruited forces. Generals Greene and Cornwallis finally met at the Battle of Guilford Courthouse in present-day Greensboro on March 15, 1781. Although the British troops held the field at the end of the battle, their casualties at the hands of the numerically superior Continental Army were crippling. Following this "Pyrrhic victory", Cornwallis chose to move to the Virginia coastline to get reinforcements, and to allow the Royal Navy to protect his battered army. This decision would result in Cornwallis' eventual defeat at Yorktown, Virginia, later in 1781. The Patriots' victory there guaranteed American independence.

What is the present day name of the city that the Battle of Guilford Courthouse was fought at?
Answer: Greensboro

Problem: Ninety-five percent of bird species are socially monogamous. These species pair for at least the length of the breeding season orin some casesfor several years or until the death of one mate. Monogamy allows for both paternal care and biparental care, which is especially important for species in which females require males' assistance for successful brood-rearing. Among many socially monogamous species, extra-pair copulation (infidelity) is common. Such behaviour typically occurs between dominant males and females paired with subordinate males, but may also be the result of forced copulation in ducks and other anatids. Female birds have sperm storage mechanisms that allow sperm from males to remain viable long after copulation, a hundred days in some species. Sperm from multiple males may compete through this mechanism. For females, possible benefits of extra-pair copulation include getting better genes for her offspring and insuring against the possibility of infertility in her mate. Males of species that engage in extra-pair copulations will closely guard their mates to ensure the parentage of the offspring that they raise.
Why do males that engage in extra-pair copulation closely guard their mates?
The answer is the following: to ensure the parentage of the offspring that they raise

Due to the top secret nature of the work, Los Alamos was isolated. In Feynman's own words, "There wasn't anything to do there." Bored, he indulged his curiosity by learning to pick the combination locks on cabinets and desks used to secure papers. Feynman played many jokes on colleagues. In one case he found the combination to a locked filing cabinet by trying the numbers he thought a physicist would use (it proved to be 271828 after the base of natural logarithms, e = 2.71828...), and found that the three filing cabinets where a colleague kept a set of atomic bomb research notes all had the same combination. He left a series of notes in the cabinets as a prank, which initially spooked his colleague, Frederic de Hoffmann, into thinking a spy or saboteur had gained access to atomic bomb secrets. On several occasions, Feynman drove to Albuquerque to see his ailing wife in a car borrowed from Klaus Fuchs, who was later discovered to be a real spy for the Soviets, transporting nuclear secrets in his car to Santa Fe.
How did Feynman spook a colleague?
left a series of notes in the cabinets

Here is a question about this article: Personnel Recovery (PR) is defined as "the sum of military, diplomatic, and civil efforts to prepare for and execute the recovery and reintegration of isolated personnel" (JP 1-02). It is the ability of the US government and its international partners to effect the recovery of isolated personnel across the ROMO and return those personnel to duty. PR also enhances the development of an effective, global capacity to protect and recover isolated personnel wherever they are placed at risk; deny an adversary's ability to exploit a nation through propaganda; and develop joint, interagency, and international capabilities that contribute to crisis response and regional stability.
What is the answer to this question: What is one of the ways that PR uses its capabilities in a crisis?
****
So...
deny an adversary's ability to exploit a nation through propaganda
