Question

the mystery began the day farmer russ kremers knee was slashed by a boar with a razor - sharp tusk. the missouri pig farmer shrugged off the wound and went back to work. later, his leg became inflamed and ballooned to twice its size. he had contracted an infection that threatened his life - and baffled doctors who wondered why two months of treatment with multiple antibiotics had done little to ease the condition. the answer was flowing in the veins of the boar: kremer had fed the animal stop laced with low doses of an antibiotic, spawning a germ that was resistant to drugs. that drug - resistant germ had passed to kremer. more and more americans - many of them living far from barns and pastures - are at risk from the widespread practice of feeding antibiotics to pigs and question 6 what is the cause and effect relationship that takes place in the article? a. farmers are using increasing amounts of antibiotics because thousands of people are dying from infections. b. there has been a rise in drug - resistant infections because antibiotics are being overused. c. some countries banned meat from the u.s. because some u.s. farmers stopped giving their animals antibiotics. d. doctors were interested to find that russ kremers leg became inflamed and ballooned to twice its size.

Explanation:

The article discusses the overuse of antibiotics by farmers (cause) and the resulting drug - resistant infections (effect). Option B correctly identifies the cause (antibiotic overuse) and effect (drug - resistant infections). Option A only mentions antibiotic use by farmers without the effect. Option C is about bans in some countries, not the main cause - effect. Option D is a specific example (Kremer's leg) rather than the general cause - effect.

Answer:

B. There has been a rise in drug - resistant infections because antibiotics are being overused.
