An island R is completely away from modern industry.People here follow subsistence agriculture method. A high % of people in Island R are affected by Hobsons disease.From the above paragraph, we can deduce (i) there must be another reason for Hobson's disease other than mercury posoning (ii) mercury poisoning can be due to other reasons than industrial pollution (iii).... (a) i only (b)ii only (c) i ,ii, iii (d) i and ii 15. fun() { int counter=1; counter++; if(counter>10) fun(); }...(some program similar to this one). the program will be executed infinetely--ans 16.
