Slide 03  Complete the flow-chart below. Choose SIX answers from the box and write the correct letter, A-l, next to Questions 21.-26.

27 A
Distraction B: Lucy mentions that fitness-related articles recommend (similar to ‘advise’) vitamins – but a health authority is a government organisation. We are not told who the authors of the articles may be. C: Lucy certainly expresses the idea in C (the price has dropped so many manufacturers are making supplements) but Sam rejects this as the reason for the increase in Australian sales.

28 C
Distraction A: Lucy refers to the Food and Drug
Administration agency, but she explains that they do not require proof that vitamins work. Therefore, the supplement industry has no guidelines to follow in this case. B: Lucy mentions that some vitamins are said to improve brain function, but this is the intended purpose of the vitamin, not a possible harmful side effect.

29 B
Distraction A: Lucy refers to ‘a simple cold’ but she says the Danish researchers found no evidence that vitamins could prevent or treat this. C: Sam mentions ‘high doses’ (large amounts) but neither he or Lucy suggest that high doses are harmful.

30 C
Distraction A: Sam puts forward the suggestion that people would stop buying vitamin supplements but Lucy rejects this idea (Hardly!) She goes on to explain why stricter regulations wouldn’t make a difference to consumer’s beliefs that vitamin supplements are worth taking. B: Lucy mentions ‘fish oil with vitamin D’ – but does not say that this product in particular should be regulated
