Input: Read this: The Somerset Coal Canal was built in the early 19th century to reduce the cost of transportation of coal and other heavy produce. The first 16 kilometres (10 mi), running from a junction with the Kennet and Avon Canal, along the Cam valley, to a terminal basin at Paulton, were in use by 1805, together with several tramways. A planned 11.7 km (7.3 mi) branch to Midford was never built, but in 1815 a tramway was laid along its towing path. In 1871 the tramway was purchased by the Somerset and Dorset Joint Railway (S&DJR), and operated until the 1950s.
Question: What was never built

Output: A planned 11.7 km (7.3 mi) branch to Midford was never built

Ah, so.. unavailability of certain crucial data

Question: Domestic geese are much larger than their wild counterparts and tend to have thick necks, an upright posture, and large bodies with broad rear ends. The greylag-derived birds are large and fleshy and used for meat, while the Chinese geese have smaller frames and are mainly used for egg production. The fine down of both is valued for use in pillows and padded garments. They forage on grass and weeds, supplementing this with small invertebrates, and one of the attractions of rearing geese is their ability to grow and thrive on a grass-based system. They are very gregarious and have good memories and can be allowed to roam widely in the knowledge that they will return home by dusk. The Chinese goose is more aggressive and noisy than other geese and can be used as a guard animal to warn of intruders. The flesh of meat geese is dark-coloured and high in protein, but they deposit fat subcutaneously, although this fat contains mostly monounsaturated fatty acids. The birds are killed either around 10 or about 24 weeks. Between these ages, problems with dressing the carcase occur because of the presence of developing pin feathers.
Try to answer this question if possible: Why is the meat of geese considered lean?
Answer: unanswerable

Question: The Mantoux tuberculin skin test is often used to screen people at high risk for TB. Those who have been previously immunized may have a false-positive test result. The test may be falsely negative in those with sarcoidosis, Hodgkin's lymphoma, malnutrition, and most notably, active tuberculosis. Interferon gamma release assays (IGRAs), on a blood sample, are recommended in those who are positive to the Mantoux test. These are not affected by immunization or most environmental mycobacteria, so they generate fewer false-positive results. However, they are affected by M. szulgai, M. marinum, and M. kansasii. IGRAs may increase sensitivity when used in addition to the skin test, but may be less sensitive than the skin test when used alone.
Try to answer this question if possible: In combination with skin tests, are IGRAs associated with an increase or decrease in sensitivity?
Answer:
increase
