Rats are often _______ with spreading disease rather than _______ it, but this long-tailed animal is highly _______ . Inside a rat's nose are up to 1,000 different types of olfactory receptors (嗅觉感受器), whereas humans only have 100 to 200 types. This gives rats the ability to detect _______ smells. As a result, some rats are being put to work to detect TB (肺结核). When the rats detect the smell, they stop and rub their legs to _______ a sample is infected.Traditionally, a hundred samples would take lab technicians more than two days to _______ , but for a rat it takes less than 20 minutes. This rat detection method doesn't rely on specialist equipment. It is also more accurate — the rats are able to find more TB infections and, therefore, save more lives.A) associated B) examine C) indicate D) nuisance E) peak F) preventing G) prohibiting H) sensitive I) slight J) specify K) superior L) suspicious M) tip N) treated O) visual
