Which statement best summarizes the thesis of the article as it is articulated in paragraphs 1–3?

• Malaria is impossible to figure out because of the lack of scientific knowledge about pathogens.

• Scientists cannot understand how malaria has evolved to become increasingly deadly the longer humans live around it. 

• Malaria is a deadly disease that perplexes scientists because it cannot be cured like most diseases.

• While most pathogens become less deadly over time, malaria remains as deadly today as it ever was.

• According to science writer Carl Zimmer, one third of all described species practice the parasitic lifestyle. (paragraph 6)

The author presents some information in a cause-and-effect format. What causes most pathogens to become less deadly over time?

• Scientists study diseases to gain more knowledge. 

• Populations build immunity to common pathogens.

• Pathogens need a living host to survive.

• People learn to avoid common sources of illness.
