Article: Digestive systems take many forms. There is a fundamental distinction between internal and external digestion. External digestion developed earlier in evolutionary history, and most fungi still rely on it. In this process, enzymes are secreted into the environment surrounding the organism, where they break down an organic material, and some of the products diffuse back to the organism. Animals have a tube (gastrointestinal tract) in which internal digestion occurs, which is more efficient because more of the broken down products can be captured, and the internal chemical environment can be more efficiently controlled.

Question: What are the two types of digestion?
Ans: internal and external digestion

Article: Starting in the 1970s, the Bronx often symbolized violence, decay, and urban ruin. The wave of arson in the South Bronx in the 1960s and 1970s inspired the observation that "The Bronx is burning": in 1974 it was the title of both a New York Times editorial and a BBC documentary film. The line entered the pop-consciousness with Game Two of the 1977 World Series, when a fire broke out near Yankee Stadium as the team was playing the Los Angeles Dodgers. Numerous fires had previously broken out in the Bronx prior to this fire. As the fire was captured on live television, announcer Howard Cosell is wrongly remembered to have said something like, "There it is, ladies and gentlemen: the Bronx is burning". Historians of New York City frequently point to Cosell's remark as an acknowledgement of both the city and the borough's decline. A new feature-length documentary film by Edwin Pagan called Bronx Burning is in production in 2006, chronicling what led up to the numerous arson-for-insurance fraud fires of the 1970s in the borough.

Question: Who made a film called 'Bronx Burning'?
Ans: Edwin Pagan

Article: Uranium-238 is the most stable isotope of uranium, with a half-life of about 4.468109 years, roughly the age of the Earth. Uranium-235 has a half-life of about 7.13108 years, and uranium-234 has a half-life of about 2.48105 years. For natural uranium, about 49% of its alpha rays are emitted by each of 238U atom, and also 49% by 234U (since the latter is formed from the former) and about 2.0% of them by the 235U. When the Earth was young, probably about one-fifth of its uranium was uranium-235, but the percentage of 234U was probably much lower than this.

Question: About how old is the Earth?
Ans: 4.468109 years

Article: Tuvaluans are well known for their seafaring skills, with the Tuvalu Maritime Training Institute on Amatuku motu (island), Funafuti, providing training to approximately 120 marine cadets each year so that they have the skills necessary for employment as seafarers on merchant shipping. The Tuvalu Overseas Seamen's Union (TOSU) is the only registered trade union in Tuvalu. It represents workers on foreign ships. The Asian Development Bank (ADB) estimates that 800 Tuvaluan men are trained, certified and active as seafarers. The ADB estimates that, at any one time, about 15% of the adult male population works abroad as seafarers. Job opportunities also exist as observers on tuna boats where the role is to monitor compliance with the boat's tuna fishing licence.

Question: What is the yearly number of cadets at the Maritime Training Institute?
Ans:
120
