iv. Shock statement
Initiating a GD with a shocking statement is the best way to capture immediate attention and put forth your point.
If a GD topic is, The Impact of Population on the Indian Economy, you could start with, 'At the centre of the Indian capital stands a population clock that ticks away relentlessly. It tracks 33 births a minute, 2,000 an hour, 48,000 a day which calculates to about 12 million every year. That is roughly the size of Australia. As a current political slogan puts it, 'Nothing's impossible when 1 billion Indians work together'.'
v. Facts, figures and statistics
If you decide to initiate your GD with facts, figure and statistics, make sure to quote them accurately.
For example, you can say, approximately 70 per cent of the Indian population stays in rural areas (macro figures, approximation allowed).
But you cannot say 30 states of India instead of 28 (micro figures, no approximations).
Stating wrong facts works to your disadvantage.
For a GD topic like, China, a Rising Tiger, you could start with, 'In 1983, when China was still in its initial stages of reform and opening up, China's real use of Foreign Direct Investment only stood at $636 million. China actually utilized $60 billion of FID in 2004, which is almost 100 times that of its 1983 statistics."
vi. Short story
Use a short story in a GD topic like, Attitude is Everything.
This can be initiated with, 'A child once asked a balloon vendor, who was selling helium gas-filled balloons, whether a blue-colored balloon will go as high in the sky as a green-colored balloon. The balloon vendor told the child, it is not the color of the balloon but what is inside it that makes it go high.'
vii. General statement
Use a general statement to put the GD in proper perspective.
For example, if the topic is, Should Sonia Gandhi be the prime minister of India?, you could start by saying, 'Before jumping to conclusions like, 'Yes, Sonia Gandhi should be', or 'No, Sonia Gandhi should not be', let's first find out the qualities one needs to be a a good prime minister of India. Then we can compare these qualities with those that Mrs. Gandhi possesses. This will help us reach the conclusion in a more objective and effective manner.'
