question: Tuberculosis (TB) is an infectious disease usually caused by the bacterium Mycobacterium tuberculosis (MTB). Tuberculosis generally affects the lungs, but can also affect other parts of the body. Most infections do not have symptoms, known as latent tuberculosis. About 10% of latent infections progress to active disease which, if left untreated, kills about half of those infected. The classic symptoms of active TB are a chronic cough with blood-containing sputum, fever, night sweats, and weight loss. The historical term "consumption" came about due to the weight loss. Infection of other organs can cause a wide range of symptoms.

One-third of the world's population is thought to be infected with TB. New infections occur in about 1% of the population each year. In 2014, there were 9.6 million cases of active TB which resulted in 1.5 million deaths. More than 95% of deaths occurred in developing countries. The number of new cases each year has decreased since 2000. About 80% of people in many Asian and African countries test positive while 510% of people in the United States population tests positive by the tuberculin test. Tuberculosis has been present in humans since ancient times.

question: (CNN) -- Defending champion Serena Williams will miss the Australian Open in January to give herself more time to recover from foot surgery.

The former world number one has not played competitively since winning her fourth Wimbledon crown in July.

She sustained the original injury after standing on broken glass at a restaurant shortly after winning her second grand slam of the year and 13th of her glittering career.

Williams attempted to come back ahead of the season-ending WTA Championships in Qatar, but had to abandon her attempts after aggravating the injury in training.

The American was also due to compete in the Hopman Cup in Australia next month, but in a statement released Thursday said she had been left with no choice but to pull out.

She said: "As I continue to rehabilitate my foot after the second surgery last month, it is with the utmost regret that I am withdrawing from the Hopman Cup and the 2011 Australian Open Championships.

"As I recently learned, pushing myself back into my intense training too early only caused me further injury and damage.

"While I desperately want to be back on the court and competing in the first grand slam tournament of the year, it is imperative for my health that I continue to work with my doctors to ensure my foot heals properly."

Williams dominated the early part of the 2010 season, with victories at the Australian Open and the grass of Wimbledon, but in her absence Caroline Wozniacki of Denmark claimed top spot in the global rankings.

question: Geodesy (/didsi/), also named geodetics, is the scientific discipline that deals with the measurement and representation of the Earth. The history of geodesy began in antiquity and blossomed during the Age of Enlightenment.

Early ideas about the figure of the Earth held the Earth to be flat (see flat Earth), and the heavens a physical dome spanning over it. Two early arguments for a spherical Earth were that lunar eclipses were seen as circular shadows which could only be caused by a spherical Earth, and that Polaris is seen lower in the sky as one travels South.

The early Greeks, in their speculation and theorizing, ranged from the flat disc advocated by Homer to the spherical body postulated by Pythagoras. Pythagoras's idea was supported later by Aristotle. Pythagoras was a mathematician and to him the most perfect figure was a sphere. He reasoned that the gods would create a perfect figure and therefore the Earth was created to be spherical in shape. Anaximenes, an early Greek philosopher, believed strongly that the Earth was rectangular in shape.

Since the spherical shape was the most widely supported during the Greek Era, efforts to determine its size followed. Plato determined the circumference of the Earth (which is slightly over 40,000km) to be 400,000 stadia (between 62,800 and 74,000km or 46,250 and 39,250mi) while Archimedes estimated 300,000 stadia (48,300km or 30,000mi), using the Hellenic stadion which scholars generally take to be 185 meters or of a geographical mile. Plato's figure was a guess and Archimedes' a more conservative approximation.
