IN: These frogs are suggested to be kept in a group of two or more due to their social nature. Despite being fully aquatic, the African dwarf frog still needs to be able to reach the surface to breathe. These amphibians are not great swimmers, so water currents should be kept low and deep tanks may pose a challenge to their ability to breathe. In the wild, the Congo forest floods yearly to a depth of 24 inches or more, so any depth less than that will be suitable. They also should be kept in an enclosure with a secure cover to prevent escape and plenty of hiding spaces as in the wild they tend to be prey to a variety of animals and open spaces cause skittish behavior. The frogs eat any smaller fish. The optimum water temperature is 75--82 F. The pH of the water should be maintained between 6.5 and 7.5. These frogs cannot survive out of water for longer than 20 minutes in low humidity, as they dry out.

IN: Zone defenses are common in international, college, and youth competition. In the National Basketball Association, zone defenses were prohibited until the 2001--2002 season, and most teams do not use them as a primary defensive strategy. The NBA has a defensive three-second violation rule, which makes it more difficult for teams to play zone, since such defenses usually position a player in the middle of the key to stop penetration. The Dallas Mavericks under coach Rick Carlisle are an example of an NBA team that have regularly used zone defenses.

IN: Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength, or Ftu within equations, is the capacity of a material or structure to withstand loads tending to elongate, as opposed to compressive strength, which withstands loads tending to reduce size. In other words, tensile strength resists tension (being pulled apart), whereas compressive strength resists compression (being pushed together). Ultimate tensile strength is measured by the maximum stress that a material can withstand while being stretched or pulled before breaking. In the study of strength of materials, tensile strength, compressive strength, and shear strength can be analyzed independently.
is tensile strength the same as breaking strength?

OPTIONS:
- no
- yes

OUT: yes

IN: With the sale of Salzgitter AG and purchase of the navigation and logistics company Hapag-Lloyd AG in 1997, Preussag AG became a global enterprise in the service and leisure industry. At that time, Hapag-Lloyd held a 30% interest in the tourism conglomerate TUI (founded 1968), increased to 100% by 1999. In addition the company acquired 25% of Thomas Cook shares in 1997, which it doubled the following year. On 2 February 1999, the Carlson Leisure Group merged with Thomas Cook into a holding company owned by the German bank, Westdeutsche Landesbank, Carlson Inc and Preussag. However, in mid-2000 Preussag acquired Thomas Cook's rival Thomson Travel and was forced to sell its majority 50.1% stake in Thomas Cook by regulatory authorities. In 2002, Preussag renamed itself TUI AG.
