Example Input: Verify if the sentiment of the following document towards the entity Liza Mundy is Neutral .  Mundy : When I was doing my research  I read the memoir of Virginia Gildersleeve  who was the dean of Barnard College. She was older than some of the women who served in the WAVES [the women's branch of the US Naval Reserve  better known as Women Accepted for Volunteer Emergency Service] like Wellesley's Mildred McAfee. She and others clearly saw what was an opportunity. Before the war  women's colleges had taught women math and science but they were reluctant to train very many women because they knew they couldn't get jobs. And so when the war started  they were still skeptical about putting too many women into math majors because they just worried that all of this was going to be yanked away after the war. But I also thought Virginia Gildersleeve was very crafty. She and some of the other leaders did see this as a way to try to persuade MIT and Columbia and other places to open up some more slots in graduate school for women. I was fascinated by the way they did see [code breaking and military recruitment] as an opportunity to expand opportunities for women even as they were worried that it would be temporary after the war.
