Google shows the source of that information. I would not like if the "Intelligent Agent" didn't show the source :)

Try "Population of India" on Google google.com/search?num=100& ... , does not give much. But try it on Ask and you get uk.ask.com/web?q=population+of ... this.

Try:

- What is the age of Billy Joel
- What is the meaning of cot

Read the post again and try "What is the population of India" :
