Much of New Delhi, planned by the leading 20th-century British architect Edwin Lutyens, was laid out to be the central administrative area of the city as a testament to Britain's imperial pretensions. New Delhi is structured around two central promenades called the Rajpath and the Janpath. The Rajpath, or King's Way, stretches from the Rashtrapati Bhavan to the India Gate. The Janpath (Hindi: "Path of the People"), formerly Queen's Way, begins at Connaught Circus and cuts the Rajpath at right angles. 19 foreign embassies are located on the nearby Shantipath (Hindi: "Path of Peace"), making it the largest diplomatic enclave in India.
What are the names of the two central promenades around which New Delhi is structured?
****
The answer: Rajpath and the Janpath

The problem: Answer a question about this article:
As a landlocked country Tajikistan has no ports and the majority of transportation is via roads, air, and rail. In recent years Tajikistan has pursued agreements with Iran and Pakistan to gain port access in those countries via Afghanistan. In 2009, an agreement was made between Tajikistan, Pakistan, and Afghanistan to improve and build a 1,300 km (810 mi) highway and rail system connecting the three countries to Pakistan's ports. The proposed route would go through the Gorno-Badakhshan Autonomous Province in the eastern part of the country. And in 2012, the presidents of Tajikistan, Afghanistan, and Iran signed an agreement to construct roads and railways as well as oil, gas, and water pipelines to connect the three countries.
What year was the agreement signed?
****
The answer: 2012

The world's largest deposit of natural bitumen, known as the Athabasca oil sands is located in the McMurray Formation of Northern Alberta. This formation is from the early Cretaceous, and is composed of numerous lenses of oil-bearing sand with up to 20% oil. Isotopic studies attribute the oil deposits to be about 110 million years old. Two smaller but still very large formations occur in the Peace River oil sands and the Cold Lake oil sands, to the west and southeast of the Athabasca oil sands, respectively. Of the Alberta bitumen deposits, only parts of the Athabasca oil sands are shallow enough to be suitable for surface mining. The other 80% has to be produced by oil wells using enhanced oil recovery techniques like steam-assisted gravity drainage.
Where are the Athabasca oil sands located?
****
The answer: Northern Alberta

As cellular metabolism/energy production requires oxygen, potentially damaging (e.g., mutation causing) compounds known as free radicals can form. Most of these are oxidizers (i.e., acceptors of electrons) and some react very strongly. For the continued normal cellular maintenance, growth, and division, these free radicals must be sufficiently neutralized by antioxidant compounds. Recently, some researchers suggested an interesting theory of evolution of dietary antioxidants. Some are produced by the human body with adequate precursors (glutathione, Vitamin C), and those the body cannot produce may only be obtained in the diet via direct sources (Vitamin C in humans, Vitamin A, Vitamin K) or produced by the body from other compounds (Beta-carotene converted to Vitamin A by the body, Vitamin D synthesized from cholesterol by sunlight). Phytochemicals (Section Below) and their subgroup, polyphenols, make up the majority of antioxidants; about 4,000 are known. Different antioxidants are now known to function in a cooperative network. For example, Vitamin C can reactivate free radical-containing glutathione or Vitamin E by accepting the free radical itself. Some antioxidants are more effective than others at neutralizing different free radicals. Some cannot neutralize certain free radicals. Some cannot be present in certain areas of free radical development (Vitamin A is fat-soluble and protects fat areas, Vitamin C is water-soluble and protects those areas). When interacting with a free radical, some antioxidants produce a different free radical compound that is less dangerous or more dangerous than the previous compound. Having a variety of antioxidants allows any byproducts to be safely dealt with by more efficient antioxidants in neutralizing a free radical's butterfly effect.
What subgroup of phytochemicals helps make up the majority of the body's antioxidants?
****
The answer:
polyphenols
