I want to know the answer to the following question:
Beyoncé used words from which Nigerian author in her song, Flawless?
All the background I'm provided with is that "She would later align herself more publicly with the movement, sampling "We should all be feminists", a speech delivered by Nigerian author Chimamanda Ngozi Adichie at a TEDxEuston conference in April 2013, in her song "Flawless", released later that year.". Is that enough to answer the question?
Answer: yes
