On 10 February 2010, the 122nd IOC session at Vancouver announced Nanjing as the host city for the 2nd Summer Youth Olympic Games. The slogan of the 2014 Youth Olympic Games was “Share the Games, Share our Dreams”. The Nanjing 2014 Youth Olympic Games featured all 28 sports on the Olympic programme and were held from 16 to 28 August. The Nanjing Youth Olympic Games Organising Committee (NYOGOC) worked together with the International Olympic Committee (IOC) to attract the best young athletes from around the world to compete at the highest level. Off the competition fields, an integrated culture and education programme focused on discussions about education, Olympic values, social challenges, and cultural diversity. The YOG aims to spread the Olympic spirit and encourage sports participation.
How many types of sports were performed in the 2014 Youth Olympic Games?
A: 28

The origin of the domestic dog (Canis lupus familiaris or Canis familiaris) is not clear. Whole genome sequencing indicates that the dog, the gray wolf and the extinct Taymyr wolf diverged at around the same time 27,000–40,000 years ago. These dates imply that the earliest dogs arose in the time of human hunter-gatherers and not agriculturists. Modern dogs are more closely related to ancient wolf fossils that have been found in Europe than they are to modern gray wolves. Nearly all dog breeds' genetic closeness to the gray wolf are due to admixture, except several Arctic dog breeds are close to the Taimyr wolf of North Asia due to admixture.
Rather than with agriculturists, dogs seemingly were during the time of who?
A: human hunter-gatherers

Crevasses can form in several different ways. Transverse crevasses are transverse to flow and form where steeper slopes cause a glacier to accelerate. Longitudinal crevasses form semi-parallel to flow where a glacier expands laterally. Marginal crevasses form from the edge of the glacier, due to the reduction in speed caused by friction of the valley walls. Marginal crevasses are usually largely transverse to flow. Moving glacier ice can sometimes separate from stagnant ice above, forming a bergschrund. Bergschrunds resemble crevasses but are singular features at a glacier's margins.
What kind of crevasses form where steep slopes cause glaciers to deccelerate?
A: unanswerable

The total complement of genes in an organism or cell is known as its genome, which may be stored on one or more chromosomes. A chromosome consists of a single, very long DNA helix on which thousands of genes are encoded.:4.2 The region of the chromosome at which a particular gene is located is called its locus. Each locus contains one allele of a gene; however, members of a population may have different alleles at the locus, each with a slightly different gene sequence.
What is encoded on a chromosome?
A:
thousands of genes
