Answer 2

My grandfather was a heavy smoker, so few people were surprised when he died of oral cancer.

In the above sentence, 'heavy' is an adjective which means 'more or worse than usual in degree'. The words 'heavy smoker' in the given sentence mean that grandfather used to smoke more than a usual degree of smoking. That's why his death with oral cancer was not a surprise for most of the people.
