Alexander Stewart Jolly (1887–1957) was a Sydney-based architect, published poet and children’s author in the early 20th century. His buildings are primarily in Sydney's northern suburbs and the north coast of New South Wales. His architectural work was strongly influenced by Frank Lloyd Wright’s School in Chicago, as well as the Arts and Crafts movement of the time.
Sydney has a lot of buildings designed by Alexander Stewart Jolly.
It is neither correct or incorrect because the article states most of his buildings are in Sydney, but it doesn't state how many there actually are. So the answer could be either a lot, or just a few.  I believe that is why it fooled the system.
