Question

1 according to the article, how has the discovery of the mimivirus influenced scientists ideas about viruses? (a) since it acts differently than other viruses, scientists think it could lead to a vaccine for cancer. (b) since it seems more like a single - celled animal, some scientists are ready to call it living. (c) since few viruses are this large, scientists now think they are related to bacteria. (d) since new viruses have emerged, scientists expect to find the origin of human life in seawater. 2 how does the article develop the idea that scientists have made progress treating viral illnesses? (a) by showing how many viruses there are, and explaining which diseases have vaccines (b) by explaining the origin of early vaccines, and describing how antivirals work (c) by describing the characteristics of viruses, and explaining how they infect hosts (d) by providing an example of an early scientist, and describing the role of antibiotics 3 read the sentences from the section vaccines are developed to stop viruses. the best vaccines have even resulted in the eradication of diseases, such as smallpox. hopefully, in the near future, polio and measles will also become illnesses of the past. the author uses the word eradication to mean: (a) management (b) opposition (c) treatment (d) elimination

Explanation:

1. Mimivirus's characteristics make some scientists consider it living as it resembles single - celled animals.
2. Explaining vaccine origin and antiviral function shows progress in treating viral illnesses.
3. "Eradication" in the context of diseases like smallpox means complete elimination.

Answer:

1. B. Since it seems more like a single - celled animal, some scientists are ready to call it "living."
2. B. by explaining the origin of early vaccines, and describing how antivirals work
3. D. elimination
