Samar is conducting research about comedian and actress lucille ball. which of her sources are secondary sources? check all that apply.

a book about ball’s impact as a performer
a television interview with ball
one of ball’s acceptance speeches
a review of ball’s television show
a chapter from ball’s autobiography
an interview with ball’s costars

I would contend that the right answers are 1) A book about Ball’s impact as a performer, 4) A review of Ball’s television show and 6) An interview with Ball’s costars.

Explanation: The question is asking specifically which of these sources are secondary sources, which are sources that interpret or discuss primary sources—firsthand evidence about a historical event, person, or artifact. An autobiography, an interview, and an acceptance speech are all direct and original evidence, since those contain Ball's actual and immediate words. However, a book about the performer, a review of her show, and an interview with her costars are not primary sources, since those are reflections and commentaries on her and on her performances made by other people.        

there is no sentence to look at.

hm, switch the relative; nominative and indefinite; objective ? not too bright in the knowledge of the english.
