Rearrange the following sentences to get a meaningful paragraph :

A. They multiply and spread from one host to the other, feeding of their hosts, weakening them, and sometimes even killing them.

B. Organic parasites, such as viruses, live inside the body of their hosts.

C. As long as the hosts live long enough to pass along the parasite, it cares little about the condition of its host.

D. Ever more scholars see cultures as a kind of mental infection or parasite, with humans as its unwitting host.

Option E is the correct answer.

Sentence D introduces the topic by drawing a comparison between cultures and parasites, portraying humans as unwitting hosts to this mental infection, and setting the stage for the discussion.

Sentence B logically follows by providing an example of organic parasites, such as viruses, which live inside their hosts, helping to establish the basis for the analogy. 

Sentence A then elaborates on the behavior of parasites, explaining how they multiply, spread, feed on their hosts, and sometimes even kill them, deepening the understanding of their impact. 

Sentence C concludes the flow by reflecting on the parasite-host relationship, emphasizing that parasites prioritize their own survival and transmission over the condition of their host, tying the discussion back to the concept introduced in Sentence D.
