Problem: San Diego's roadway system provides an extensive network of routes for travel by bicycle. The dry and mild climate of San Diego makes cycling a convenient and pleasant year-round option. At the same time, the city's hilly, canyon-like terrain and significantly long average trip distances—brought about by strict low-density zoning laws—somewhat restrict cycling for utilitarian purposes. Older and denser neighborhoods around the downtown tend to be utility cycling oriented. This is partly because of the grid street patterns now absent in newer developments farther from the urban core, where suburban style arterial roads are much more common. As a result, a vast majority of cycling-related activities are recreational. Testament to San Diego's cycling efforts, in 2006, San Diego was rated as the best city for cycling for U.S. cities with a population over 1 million.
Why are older neighborhoods in San Diego popular with cyclists?
The answer is the following: the grid street patterns

Problem: The Mogadishu-based Somali National Television is the principal national public service broadcaster. On March 18, 2011, the Ministry of Information of the Transitional Federal Government began experimental broadcasts of the new TV channel. After a 20-year hiatus, the station was shortly thereafter officially re-launched on April 4, 2011. SNTV broadcasts 24 hours a day, and can be viewed both within Somalia and abroad via terrestrial and satellite platforms.
What year did experimental broadcasts of Somali National Television begin?
The answer is the following: 2011

Problem: Many[who?] expected BSkyB to make a bid to show some of the remaining FA Cup games for the remainder of the 2009–10 season which would include a semi-final and shared rights to the final. ESPN took over the package Setanta held for the FA Cup from the 2010–11 season. The 2011 final was also shown live on Sky 3D in addition to ESPN (who provided the 3D coverage for Sky 3D) and ITV. Following the sale of ESPN's UK and Ireland channels to BT, ESPN's rights package transferred to BT Sport from the 2013–14 season.
Who took over after ESPN? 
The answer is the following: BT Sport

Problem: Epigenetics is the study of mitotically and/or meiotically heritable changes in gene function that cannot be explained by changes in the underlying DNA sequence but cause the organism's genes to behave (or "express themselves") differently. One example of epigenetic change is the marking of the genes by DNA methylation which determines whether they will be expressed or not. Gene expression can also be controlled by repressor proteins that attach to silencer regions of the DNA and prevent that region of the DNA code from being expressed. Epigenetic marks may be added or removed from the DNA during programmed stages of development of the plant, and are responsible, for example, for the differences between anthers, petals and normal leaves, despite the fact that they all have the same underlying genetic code. Epigenetic changes may be temporary or may remain through successive cell divisions for the remainder of the cell's life. Some epigenetic changes have been shown to be heritable, while others are reset in the germ cells.
What does epigenetics study?
The answer is the following:
changes in gene function
