In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[Q]: What can a tree produce after it is mature?, Context: Different pieces of wood cut from a large tree may differ decidedly, particularly if the tree is big and mature. In some trees, the wood laid on late in the life of a tree is softer, lighter, weaker, and more even-textured than that produced earlier, but in other trees, the reverse applies. This may or may not correspond to heartwood and sapwood. In a large log the sapwood, because of the time in the life of the tree when it was grown, may be inferior in hardness, strength, and toughness to equally sound heartwood from the same log. In a smaller tree, the reverse may be true.
[A]: wood


[Q]: What was the school's channel called?, Context: Imperial College TVICTV (formerly STOIC (Student Television of Imperial College)) is Imperial College Union's TV station, founded in 1969 and operated from a small TV studio in the Electrical Engineering block. The department had bought an early AMPEX Type A 1-inch videotape recorder and this was used to produce an occasional short news programme which was then played to students by simply moving the VTR and a monitor into a common room. A cable link to the Southside halls of residence was laid in a tunnel under Exhibition Road in 1972. Besides the news, early productions included a film of the Queen opening what was then called College Block and interview programmes with DJ Mike Raven, Richard O'Brian and Monty Python producer Ian MacNaughton. The society was renamed to ICTV for the start of the 2014/15 academic year.
[A]: STOIC


[Q]: The university steadily did what?, Context: The first degrees from the college were awarded in 1849. The university was expanded with new buildings to accommodate more students and faculty. With each new president, new academic programs were offered and new buildings built to accommodate them. The original Main Building built by Sorin just after he arrived was replaced by a larger "Main Building" in 1865, which housed the university's administration, classrooms, and dormitories. Beginning in 1873, a library collection was started by Father Lemonnier. By 1879 it had grown to ten thousand volumes that were housed in the Main Building.
