Problem: Tuberculosis:

In 1520% of active cases, the infection spreads outside the lungs, causing other kinds of TB. These are collectively denoted as "extrapulmonary tuberculosis". Extrapulmonary TB occurs more commonly in immunosuppressed persons and young children. In those with HIV, this occurs in more than 50% of cases. Notable extrapulmonary infection sites include the pleura (in tuberculous pleurisy), the central nervous system (in tuberculous meningitis), the lymphatic system (in scrofula of the neck), the genitourinary system (in urogenital tuberculosis), and the bones and joints (in Pott disease of the spine), among others. When it spreads to the bones, it is also known as "osseous tuberculosis", a form of osteomyelitis. Sometimes, bursting of a tubercular abscess through skin results in tuberculous ulcer. An ulcer originating from nearby infected lymph nodes is painless, slowly enlarging and has an appearance of "wash leather". A potentially more serious, widespread form of TB is called "disseminated tuberculosis", also known as miliary tuberculosis. Miliary TB makes up about 10% of extrapulmonary cases.

What's the medical term for TB when it spreads from the lungs to other parts of the body?

A: extrapulmonary tuberculosis

Problem: The Color Orange democracy group, led by Danish sculptor Jens Galschit, originally planned to join the Hong Kong Alliance relay and paint the "Pillar of Shame", a structure he built in Hong Kong to commemorate the 1989 Tiananmen Square protests. However, Galschit and two other people were denied entry to Hong Kong on April 26, 2008 due to "immigration reasons" and were forced to leave Hong Kong. In response, Lee Cheuk Yan, vice chairman of the Hong Kong Alliance in Support of Patriotic Democratic Movements in China, said, "It's outrageous that the government is willing to sacrifice the image of Hong Kong because of the torch relay." Hollywood actress Mia Farrow was also briefly questioned at the Hong Kong airport though officials allowed her to enter. She later gave a speech criticizing China's relations with Sudan in Hong Kong, as there was also a small minority of people protesting about China's role in the crisis of Darfur. Legislator Cheung Man Kwong have also said the government's decision allowing Farrow to enter while denying others is a double standard and a violation to Hong Kong's one country, two systems policy.
A legislator said that by allowing Farrow to enter Hong Kong while denying others was a violation to what policy?

Answer: one country, two systems

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
While the use of iron started to become more widespread around 1200 BC, mainly because of interruptions in the trade routes for tin, the metal is much softer than bronze. However, very small amounts of steel, (an alloy of iron and around 1% carbon), was always a byproduct of the bloomery process. The ability to modify the hardness of steel by heat treatment had been known since 1100 BC, and the rare material was valued for the manufacture of tools and weapons. Because the ancients could not produce temperatures high enough to melt iron fully, the production of steel in decent quantities did not occur until the introduction of blister steel during the Middle Ages. This method introduced carbon by heating wrought iron in charcoal for long periods of time, but the penetration of carbon was not very deep, so the alloy was not homogeneous. In 1740, Benjamin Huntsman began melting blister steel in a crucible to even out the carbon content, creating the first process for the mass production of tool steel. Huntsman's process was used for manufacturing tool steel until the early 1900s.
The softness of what could be modified in 1100 BC?
A: unanswerable

Context and question: Indonesia is the largest country in Southeast Asia and it also the largest archipelago in the world by size (according to the CIA World Factbook). Geologically, the Indonesian Archipelago is one of the most volcanically active regions in the world. Geological uplifts in the region have also produced some impressive mountains, culminating in Puncak Jaya in Papua, Indonesia at 5,030 metres (16,500 feet), on the island of New Guinea; it is the only place where ice glaciers can be found in Southeast Asia. The second tallest peak is Mount Kinabalu in Sabah, Malaysia on the island of Borneo with a height of 4,095 metres (13,435 feet). The highest mountain in Southeast Asia is Hkakabo Razi at 5,967 meters and can be found in northern Burma sharing the same range of its parent peak, Mount Everest.
What is the largest country in Asia?
Answer: unanswerable

Question: On July 11, 1877, a few days after the Bell Telephone Company was established, Bell married Mabel Hubbard (18571923) at the Hubbard estate in Cambridge, Massachusetts. His wedding present to his bride was to turn over 1,487 of his 1,497 shares in the newly formed Bell Telephone Company. Shortly thereafter, the newlyweds embarked on a year-long honeymoon in Europe. During that excursion, Bell took a handmade model of his telephone with him, making it a "working holiday". The courtship had begun years earlier; however, Bell waited until he was more financially secure before marrying. Although the telephone appeared to be an "instant" success, it was not initially a profitable venture and Bell's main sources of income were from lectures until after 1897. One unusual request exacted by his fiancee was that he use "Alec" rather than the family's earlier familiar name of "Aleck". From 1876, he would sign his name "Alec Bell". They had four children:
Is there an answer to this question: How many children did Bell and Mabel have?

Answer: 4
