Grateful if someone would tell me why sentense 1 is not "the harassment of women" while sentense 2 uses "the" for "pursuit of happiness". <br/><br/>1. "The worst social problems are alchohol addiction, bullying among students, harassment of women, and the aging of society."<br/><br/>2. "An American likes to feel good about him or herself, and "the pursuit of happiness" is one of the rights guaranteed by the US Constitution."<br/><br/>Thank you!
