Your assignment in the second class project is to explore some question (or set of related questions) concerning the rise of do support on the basis of the parsed corpora available to you in this class. You should use both corpora.
You can polish the results from previous assignments, investigate some of the same questions as Kroch 1989 and Warner 2005, go beyond their results, or explore questions that are not directly related to the readings. The same topic can be explored by more than one student, and you are welcome to discuss the topics among yourselves, but when you write up your results, you should do so independently.
Feel free to come talk to me or Marielle about your projects. Please also take advantage of the "solutions" to Assignments 9 and 10, which reflect the guidelines for the project.
