Answer:
The correct answer would be "Coffee drinking has definable effects on the human body."
It helps to think for a moment that the ONLY information you know about coffee is "Heavy coffee drinkers may experience headaches if they suddenly quit drinking coffee." Based on this, what would you infer?
Most definitely not "Coffee drinking can cure many kinds of headaches."
"Coffee is a delicious drink enjoyed by many people." <-- The text does not mention the taste of coffee anywhere
There is no mention of dark or light coffee anywhere ! "Dark coffees have a different taste than lighter coffees."
so, your answer is the first option
