Suppose J.K. Rowling, the author of the Harry Potter book series, was born in Yate, Gloucestershire, England. She began writing the first book, "Harry Potter and the Philosopher's Stone", in 1990 and it was published in 1997. The series has since become a cultural phenomenon, with millions of copies sold worldwide and a successful film franchise.
Can we infer that "J.K. Rowling started writing the first Harry Potter book in 1997"? Yes, no, or maybe?
