Article: The South Atlantic Express, a 10,000 km (6,214 mi) submarine communications cable connecting Africa to South America, run by the undersea fibre optic provider eFive, will pass St Helena relatively closely. There were no plans to land the cable and install a landing station ashore, which could supply St Helena's population with sufficient bandwidth to fully leverage the benefits of today's Information Society. In January 2012, a group of supporters petitioned the UK government to meet the cost of landing the cable at St Helena. On 6 October 2012, eFive agreed to reroute the cable through St. Helena after a successful lobbying campaign by A Human Right, a San Francisco-based NGA working on initiatives to ensure all people are connected to the Internet. Islanders have sought the assistance of the UK Department for International Development and Foreign and Commonwealth Office in funding the £10m required to bridge the connection from a local junction box on the cable to the island. The UK Government have announced that a review of the island's economy would be required before such funding would be agreed to.

Question: Who runs the South Atlantic Express?
Ans: eFive


Article: Each trace consists of a flat, narrow part of the copper foil that remains after etching. The resistance, determined by width and thickness, of the traces must be sufficiently low for the current the conductor will carry. Power and ground traces may need to be wider than signal traces. In a multi-layer board one entire layer may be mostly solid copper to act as a ground plane for shielding and power return. For microwave circuits, transmission lines can be laid out in the form of stripline and microstrip with carefully controlled dimensions to assure a consistent impedance. In radio-frequency and fast switching circuits the inductance and capacitance of the printed circuit board conductors become significant circuit elements, usually undesired; but they can be used as a deliberate part of the circuit design, obviating the need for additional discrete components.

Question: Along with thickness, what determines the resistance of a trace?
Ans: width


Article: An example of a state initiative to promote nutrition literacy is Smart Bodies, a public-private partnership between the state’s largest university system and largest health insurer, Louisiana State Agricultural Center and Blue Cross and Blue Shield of Louisiana Foundation. Launched in 2005, this program promotes lifelong healthful eating patterns and physically active lifestyles for children and their families. It is an interactive educational program designed to help prevent childhood obesity through classroom activities that teach children healthful eating habits and physical exercise.

Question: What does the initiative specifically target?
Ans: childhood obesity


Article: Nearly all polychaetes have parapodia that function as limbs, while other major annelid groups lack them. Parapodia are unjointed paired extensions of the body wall, and their muscles are derived from the circular muscles of the body. They are often supported internally by one or more large, thick chetae. The parapodia of burrowing and tube-dwelling polychaetes are often just ridges whose tips bear hooked chetae. In active crawlers and swimmers the parapodia are often divided into large upper and lower paddles on a very short trunk, and the paddles are generally fringed with chetae and sometimes with cirri (fused bundles of cilia) and gills.

Question: What are cirri?
Ans:
fused bundles of cilia
