Problem: Gene:

The theories developed in the 1930s and 1940s to integrate molecular genetics with Darwinian evolution are called the modern evolutionary synthesis, a term introduced by Julian Huxley. Evolutionary biologists subsequently refined this concept, such as George C. Williams' gene-centric view of evolution. He proposed an evolutionary concept of the gene as a unit of natural selection with the definition: "that which segregates and recombines with appreciable frequency.":24 In this view, the molecular gene transcribes as a unit, and the evolutionary gene inherits as a unit. Related ideas emphasizing the centrality of genes in evolution were popularized by Richard Dawkins.

Who proposed an evolutionary concept of the gene as a unit of natural selection?

A: George C. Williams

Problem: St. John%27s, Newfoundland and Labrador:

The earliest record of the location appears as Sao Joao on a Portuguese map by Pedro Reinel in 1519. When John Rut visited St. John's in 1527 he found Norman, Breton and Portuguese ships in the harbour. On 3 August 1527, Rut wrote a letter to King Henry on the findings of his voyage to North America; this was the first known letter sent from North America. St. Jehan is shown on Nicholas Desliens' world map of 1541 and San Joham is found in Joao Freire's Atlas of 1546. It was during this time that Water Street was first developed, making it the oldest street in North America.[dubious discuss]

What is the oldest street in the America's?
---
A: unanswerable

Problem: Predation:

Parasites can at times be difficult to distinguish from grazers. Their feeding behavior is similar in many ways, however they are noted for their close association with their host species. While a grazing species such as an elephant may travel many kilometers in a single day, grazing on many plants in the process, parasites form very close associations with their hosts, usually having only one or at most a few in their lifetime. This close living arrangement may be described by the term symbiosis, "living together", but unlike mutualism the association significantly reduces the fitness of the host. Parasitic organisms range from the macroscopic mistletoe, a parasitic plant, to microscopic internal parasites such as cholera. Some species however have more loose associations with their hosts. Lepidoptera (butterfly and moth) larvae may feed parasitically on only a single plant, or they may graze on several nearby plants. It is therefore wise to treat this classification system as a continuum rather than four isolated forms.

How are parasites distiguished from grazers?
---
A: close association with their host species

Problem: Space Race:

In May 1972, President Richard M. Nixon and Soviet Premier Leonid Brezhnev negotiated an easing of relations known as detente, creating a temporary "thaw" in the Cold War. In the spirit of good sportsmanship, the time seemed right for cooperation rather than competition, and the notion of a continuing "race" began to subside.

When did President Nixon and Brezhnev of the USSR end the Cold War?

A:
May 1972
