of a doctor who has received gifts from those companies, but this fact does not influence his decision 
in prescribing medicine. So, the correct heading for this paragraph is “Not all doctors are persuaded” 
=> ANSWER: i
6.PARAGRAPH F 
This paragraph states that a study conducted by the University of Washington has shown the

that the availability of samples led them to dispense and prescribe drugs that differed from their 
preferred drug choice.” So, the correct heading for this paragraph is “Research shows that promotion 
works” 
+ research = a study 
=> ANSWER: vii

prescription prices” and that pharmaceutical companies will continue to find ways to increase sales and 
make profits. So, the correct heading for this paragraph is “Who really pays for doctors‟ free gifts?”
