The polarization of an antenna refers to the orientation of the electric field (E-plane) of the radio wave with respect to the Earth's surface and is determined by the physical structure of the antenna and by its orientation; note that this designation is totally distinct from the antenna's directionality. Thus, a simple straight wire antenna will have one polarization when mounted vertically, and a different polarization when mounted horizontally. As a transverse wave, the magnetic field of a radio wave is at right angles to that of the electric field, but by convention, talk of an antenna's "polarization" is understood to refer to the direction of the electric field.
What is another name for electric-field?
A: E-plane

Southampton has always been a port, and the docks have long been a major employer in the city. In particular, it is a port for cruise ships; its heyday was the first half of the 20th century, and in particular the inter-war years, when it handled almost half the passenger traffic of the UK. Today it remains home to luxury cruise ships, as well as being the largest freight port on the Channel coast and fourth largest UK port by tonnage, with several container terminals. Unlike some other ports, such as Liverpool, London, and Bristol, where industry and docks have largely moved out of the city centres leaving room for redevelopment, Southampton retains much of its inner-city industry. Despite the still active and expanding docklands to the west of the city centre, further enhanced with the opening of a fourth cruise terminal in 2009, parts of the eastern docks have been redeveloped; the Ocean Village development, which included a local marina and small entertainment complex, is a good example. Southampton is home to the headquarters of both the Maritime and Coastguard Agency and the Marine Accident Investigation Branch of the Department for Transport in addition to cruise operator Carnival UK.
In what year did Southampton's fourth cruise terminal open in the western docklands?
A: 2009

Hidalgo is hailed as the Father of the Nation even though it was Agustin de Iturbide and not Hidalgo who achieved Mexican Independence in 1821. Shortly after gaining independence, the day to celebrate it varied between September 16, the day of Hidalgo's Grito, and September 27, the day Iturbide rode into Mexico City to end the war. Later, political movements would favor the more liberal Hidalgo over the conservative Iturbide, so that eventually September 16, 1810 became the officially recognized day of Mexican independence. The reason for this is that Hidalgo is considered to be "precursor and creator of the rest of the heroes of the (Mexican War of) Independence." Hidalgo has become an icon for Mexicans who resist tyranny in the country. Diego Rivera painted Hidalgo's image in half a dozen murals. Jose Clemente Orozco depicted him with a flaming torch of liberty and considered the painting among his best work. David Alfaro Siqueiros was commissioned by San Nicolas University in Morelia to paint a mural for a celebration commemorating the 200th anniversary of Hidalgo's birth. The town of his parish was renamed Dolores Hidalgo in his honor and the state of Hidalgo was created in 1869. Every year on the night of 1516 September, the president of Mexico re-enacts the Grito from the balcony of the National Palace. This scene is repeated by the heads of cities and towns all over Mexico. The remains of Miguel Hidalgo y Costilla lie in the column of the Angel of Independence in Mexico City. Next to it is a lamp lit to represent the sacrifice of those who gave their lives for Mexican Independence.
In which city do Hidalgo's remains lie?
A: Mexico City.

Thrombolysis involves the administration of medication that activates the enzymes that normally destroy blood clots. Thrombolysis agents include streptokinase, reteplase, alteplase, and tenecteplase. If no contraindications are present (such as a high risk of bleeding), thrombolysis can be given in the pre-hospital or in-hospital setting. When given to people suspected of having a STEMI within 6 hours of the onset of symptoms, thrombolytic drugs save the life of 1 in 43 who received them. The risks were major bleeding (1 in 143) and brain bleeding (1 in 250). It is unclear whether pre-hospital thrombolysis reduces death in people with STEMI compared to in-hospital thrombolysis. Pre-hospital thrombolysis reduces time to thrombolytic treatment, based on studies conducted in higher income countries.
If thrombolytic drugs are given after 6 hours of onset, what are the odds of bleeding?
A:
unanswerable
