The correct answers are (A.) A book about Ball's impact as a performer; (D.) A review of Ball's television show and (F.) An interview with Ball's costars

Explanation:

Generally speaking, sources can be classified into primary or secondary. A primary source is one that works as a first-hand account of one event or in this case the life of someone. On the other hand, a secondary source is a type of source that interprets, analyses or summarizes one primary source, which means the author of this is not necessarily close to the event or person the source describes but uses primary sources to create a new source.

This means in the case of the actress Lucille Ball a primary source is one in which the life, words or actions of Ball's are directly recorded or one created by herself including her words, texts, performance or similar and a secondary source is one that uses one of these materials to describe the life of Ball without recording her directly. Considering this, the sources that can be classified as secondary are "a book about Ball’s impact as a performer", "a review of Ball’s television show", "an interview with Ball’s costars" as these sources do not record Ball directly but analyzed other sources such as Ball's performance or show, also, in the case of the interview with Ball's coasters the source does not focus on recording Ball but people that is close to her which is also considered as secondary.

the answer is somber
