Why didn’t people believe dr. goldberger’s conclusion about the cause of pellagra? give two reasons?

In claiming that pellagra was a nutritional disorder rather than an infectious disease, Dr. Goldberger went against established medical tradition.

Furthermore, pellagra was prevalent in orphanages in the southern United States, and southerners were irate to think that the diet they were feeding their wards was deficient. But a diet of gruel made from corn meal didn't cut the mustard.

overtime, the civil rights movement changed in a way that not only it benefited african-americans, but benefited other ethnicity's such as latinos, asians, or women too! that's why the results of the movement be called mixed.

the civil rights movement brought about tremendous changes. no longer were blacks denied the right to vote, to eat, shop, and swim where they , and more importantly, to attend integrated schools. despite its many accomplishments, however, the civil rights movement had its shortcomings. for example, many people, both young and old, lost their lives, homes, jobs, and families. still other individuals were so damaged by psychological trauma that they ceased being productive members of the community. the movement left intact the economic inequities that had contributed to the maintenance of segregation. and finally, racism remained alive and well long after the movement's end. like most movements of its kind, the civil rights movement left behind a mixed legacy of triumph and tragedy.
