Answer:
Fact
Step-by-step explanation:
A "fact" is something that is considered true and is verifiable while an "opinion" is just a belief or a judgment towards something. An opinion doesn't necessarily mean it's true.
Mrs. Aphra Behn is considered to be one of the theater's first woman playwrights. She wrote in order to pay her debts, which she was forced into after her husband died. It is said that she had written around 20 plays. These information are true, thus the statement above is a fact.
