Answer 2

Inventions in certain branches of Science are going to give immense benefit to humankind.

1. Robotics: This branch of Science designs, makes and operates robots which help in doing all kinds of work in industries at homes. By the end of his century, probably every house will have at least one robot to work.
2. Human cloning: This branch of Science will make it possible to clone a human being. This will enable to replace faulty organs and regenerate lost limbs. For example, if a person loses a leg, a few cells of his/her body would be taken and a new leg would be developed using this method.
3. Computer Application: This branch of Science would make most of the things entirely automated from machines at homes, traffic lights on streets to fighter planes, making people's life more comfortable and giving them more time for recreation.
4. Energy Technology: This branch of Science would explore pollution-free energy from wind, biogas and the Sun. Technology of generating energy by nuclear fusion will provide an inexhaustible source of non-polluting energy at a nominal cost.
5. Genetic Engineering: This branch of Science will enable the parents to determine intelligence, even hair and eye colour of their child while curing any possible dangerous genetic defect by designing the human embryo.
