Problem: Renewable energy commercialization:

Many energy markets, institutions, and policies have been developed to support the production and use of fossil fuels. Newer and cleaner technologies may offer social and environmental benefits, but utility operators often reject renewable resources because they are trained to think only in terms of big, conventional power plants. Consumers often ignore renewable power systems because they are not given accurate price signals about electricity consumption. Intentional market distortions (such as subsidies), and unintentional market distortions (such as split incentives) may work against renewables. Benjamin K. Sovacool has argued that "some of the most surreptitious, yet powerful, impediments facing renewable energy and energy efficiency in the United States are more about culture and institutions than engineering and science".

 Why do utility operators only ever accept renewable resources?

Problem: Virgil:

The Aeneid is widely considered Virgil's finest work and one of the most important poems in the history of western literature. Virgil worked on the Aeneid during the last eleven years of his life (29–19 BC), commissioned, according to Propertius, by Augustus. The epic poem consists of 12 books in dactylic hexameter verse which describe the journey of Aeneas, a warrior fleeing the sack of Troy, to Italy, his battle with the Italian prince Turnus, and the foundation of a city from which Rome would emerge. The Aeneid's first six books describe the journey of Aeneas from Troy to Rome. Virgil made use of several models in the composition of his epic; Homer, the preeminent author of classical epic, is everywhere present, but Virgil also makes special use of the Latin poet Ennius and the Hellenistic poet Apollonius of Rhodes among the various other writers to which he alludes. Although the Aeneid casts itself firmly into the epic mode, it often seeks to expand the genre by including elements of other genres such as tragedy and aetiological poetry. Ancient commentators noted that Virgil seems to divide the Aeneid into two sections based on the poetry of Homer; the first six books were viewed as employing the Odyssey as a model while the last six were connected to the Iliad.

Which of Homer's works did the last six books of the Aeneid connect to?
---
A: Iliad


Problem: Uranium:

Two major types of atomic bombs were developed by the United States during World War II: a uranium-based device (codenamed "Little Boy") whose fissile material was highly enriched uranium, and a plutonium-based device (see Trinity test and "Fat Man") whose plutonium was derived from uranium-238. The uranium-based Little Boy device became the first nuclear weapon used in war when it was detonated over the Japanese city of Hiroshima on 6 August 1945. Exploding with a yield equivalent to 12,500 tonnes of TNT, the blast and thermal wave of the bomb destroyed nearly 50,000 buildings and killed approximately 75,000 people (see Atomic bombings of Hiroshima and Nagasaki). Initially it was believed that uranium was relatively rare, and that nuclear proliferation could be avoided by simply buying up all known uranium stocks, but within a decade large deposits of it were discovered in many places around the world.

What was the codename of the plutonium-based bomb destroyed in the Second World War?

Problem: Hunting:

On 16 March 1934, President Franklin D. Roosevelt signed the Migratory Bird Hunting Stamp Act, which requires an annual stamp purchase by all hunters over the age of sixteen. The stamps are created on behalf of the program by the US Postal Service and depict wildlife artwork chosen through an annual contest. They play an important role in habitat conservation because ninety-eight percent of all funds generated by their sale go directly toward the purchase or lease of wetland habitat for protection in the National Wildlife Refuge System.[citation needed] In addition to waterfowl, it is estimated that one third of the nation's endangered species seek food and shelter in areas protected using Duck Stamp funds.[citation needed]

What percentage of the endangered species seek food and shelter in areas protected using Duck Stamp Funds.
---
A:
one third
