Question:
The Lines of Communication were English Civil War fortifications commissioned by Parliament  and built around London between 1642 and 1643 to protect the capital from attack by the Royalist armies of Charles I. In 1642 some basic fortifications were built, in the form of street barricades and small earthworks. In 1643 a major construction effort was made, to provide a comprehensive ring of fortifications around the city. Much of the work was done by volunteer labour, organized by the trained bands and the livery companies. Up to 20,000 people are thought to be involved, and the works were completed in under two months. The fortifications failed their only test when the New Model Army entered London in 1647, and they were levelled by Parliament the same year.

How many years after completing the fortification around the city did the fortifications fail and were leveled?

Answer:
4

Question:
Lower subalpine forest , 450-1,000 m , is characterized by deciduous or mixed forest. The fragments of forests similar to natural complexes of pine-fir-beech with admixture of larch, sycamore maple and lime occur near the Szklarski waterfall, in the Jagniątkowski complex, and Chojnik Mountain. Particular species of trees have different climatic requirements. The lowest parts are covered with oak and ash, up to 500 m . On the level of 500-600 m  occurs pine; in the higher parts, up to 800 m , there occurs European larch; and above 800 m, fir and beech. Despite of transformation of the basic tree vegetation, the same form of undergrowth survived. There occurs: daphne mezereum, red elderberry, hazel, platanthera bifolia, sweet woodruff, herb paris, cranberry, wood sorrel, chickweed wintergreen, Common Cow-wheat and lily of the valley. The parts over 800 m are mainly covered with grasses, purple small-reeds, cranberries, and willow gentian. In highlighted places, on meadows, and along roads, there occurs: spotted orchid, bugleweed, yellow archangel, arnica montana, sword-leaved helleborine, rosebay willowherb, groundsel, and foxglove. Along riversides, there occurs white butterbur. Pine forests are rich in spruces, which are permanently weakened by atmospheric factors. Frayed roots are easily infected by harmful fungus and insects. The most damaging is honey mushroom, with edible specimen, which grows in pulp, between the bark and timber, causing the death of tree. The other damaging fungus is bracket fungus, which destroys roots and trunks from the inside. The honey mushroom devastates the tree within a few months, and the bracket fungus, within a few years, as a result of mechanic changes in wood structure.

Which takes longer to destroy a tree, honey mushroom or bracket fungus?

Answer:
bracket fungus
