Answer:
1 . I have had lunch .
2. He has had lunch .
3. I had had lunch before you came.
Explanation:
This is one of the most confused about combinations as per my experience .I would firstly tell a bit of grammar part and then clarify with real day to day usage .
THE CONFUSION IF AT ALL COMES IS BECAUSE OF TWO DIFFERENT USAGES OF WORD “HAVE” . THEY LOOK AND SOUND LIKE SAME BUT PLEASE TREAT THEM DIFFERENTLY . So let's separate them like one of them is same like “ “AM,ARE,WILL,SHALL, “ the helping or auxiliary verbs ,and the second. “have “ is just like “ drive, eat, drink, watch” the main verb “ or I prefer to call “ Action”.
The Tipping Point by Malcolm Gladwell is a book about how small actions at the right time, in the right place, and with the right people can create a "tipping point" for anything from a product to an idea to a trend. Gladwell is not a sociologist, but he relies on sociological studies, and those from other disciplines within the social sciences to write articles and books that both the general public and social scientists find fascinating and worthwhile. According to Gladwell, the "tipping point" is "that magic moment when an idea, trend, or social behavior crosses a threshold, tips, and spreads like wildfire."
According to Gladwell, there are three variables that determine whether and when the tipping point for a product, idea, or phenomenon will be achieved: The Law of the Few, the Stickiness Factor, and the Power of Context.
