Answer:
D. Biographers must make choices when they select the events they will write about.
Step-by-step explanation:
from the question there is the word bias so it means there is preference on something
Would a biographer have memories about the life someone else lived (lives)?
Would every biographer select the same things to include in a biography? If not,what would the choices between pieces of information show about the biographer?
Are all biographies about dead people?
Are all biographers writing about people they don't know, especially after they research or interview?
Biographers must take choices when selecting the events to write about.
Why?
A) is false, because not all biographers "remember" the person they are writing about. (Some write long after the person is dead.)
C) is false, because not all biographies are written long after the person is dead. (Some are written when the person is still alive).
B) is false, because some biographers actually DO know their subjects.
So the only real option is D) ... you can't write about EVERY event that takes place in the subject's life.
