Answer: B.
1. Certain diseases have disappeared, thanks to better and healthcare Keywords: certain disease, disappeared, thanks to, better, healthcare
In the first sentence of the first paragraph, the author wrote: “many diseases that affect humans have been eradicated due to improvements in vaccinations and the availability of healthcare”. “diseases have been eradicated” means people are able to “get rid of those diseases completely”, or we can say that those diseases have disappeared completely. “Due to” is the same as “thanks to”, and “improvements” refers to “something better”. In this sentence, the author mentioned 2 things – “vaccinations” and “the availability of healthcare”. “Healthcare” is mentioned in the statement already, thefore, what we are looking for is “vaccinations”. The answer is “vaccinations”.
Eradicate = disappear
Improvements = better
Answer: vaccinations
1. Because there is more contact between people, _ usefulness.
Keywords: contact between people, lose, usefulness
are losing their
In the next sentences of the first paragraph, the author mentioned “contact between people” – “In a world that is far more globalised than ever before, people come into contact with one another through travel and living closer and closer to each other. As a result, super-viruses and other infections resistant to antibiotics are becoming
more and more common.” The first sentence let us know that “there is more contact between people” (more globalized, come into contact with one another, closer and closer), and the second one showed its consequence (as a result) that is “super- viruses and other infections resistant to antibiotics are becoming more and more common”. “Resistant to antibiotics” means antibiotics are not useful to combat those superviruses and other infections. They are losing their usefulness since those super-viruses are becoming more common. Therefore, the answer is antibiotics.
