## Why these answers are right

**27. iv.** Paragraph B is packed with numbers: use for more than a decade, over 10,000 facilities, some 60 companies earning at least $22 million, and an expected $50 million by 1999. Because figures carry the paragraph, The figures say it all fits B.

**28. vii.** Paragraph C explains the process: systems store a digitized record of a unique human feature, then scan a user and match the features against the record. Describing how the systems operate matches the question heading How does it work?

**29. viii.** The key idea in paragraph D is that sixteen American states use fingerprint checks to make sure welfare claimants are genuine, and Toronto plans the same. Checking that claimants are genuine is a way of stopping false claims, so Fighting fraud fits.
