Column I some disorders associated with brain. Column II the causes for these disorders. Match the two column and identify the correct option from those given: {:("Column-I","Column-II"),(A" Epilepsy", p" Degeneration of neurons in the cerebral cortex"),(B" Alzheimer's disease", q" Irregular electrical discharge in the neurons"),(C" Parkinson's disease", r" Decreased production of acetylcholine"),(D" Huntington's chorea", s" Regeneration of dopamine releasing neurons"),(,t" Formation of blood dots in the brain"):}

First read a passage and then answer the questions following that passage. Soil scientists have shown that the soil teems with millions of living things, many of them useful, others harmful. The living things which are useful include earthworms and various kinds of bacteria. Earthworms loosen the soil and so enable air and water to enter it. Bacteria, which are microscopic living things break down dead plants and animals and make humus, or take nitrogen from the air and change it into substances that plants use. The living things that do harm include other bacteria and fungi which cause diseases. Other harmful things are pests such as wire worms which feed on the roots of grass and other plants. While the farmer can usually keep weeds in check by careful cultivation, this alone may not protect his crops from insects, pests and diseases. Nowadays, however, he is much better able to control these enemies. He may plant. specially resistant types of seeds or he may keep the pests and diseases in check with chemicals. With better seeds farmers have been able to increase their crop yield . They can grow crops that ripen more quickly and have a stronger resistance to disease, frost or drought. Nowadays it is possible to reduce the loss caused by pests and harmful bacteria
