How to fix the data import?

Two optional arguments that you can add to .read_csv() to better represent the data from an external file are:

na_values: Converts a given string to np.nan, defaults to None
parse_dates: Reads the data in a list of given columns as dtype datetime64, defaults to False

Which of the following steps should you take to make sure that the data imported from nasdaq-listings.csv are accurately represented?

The nasdaq DataFrame that you created in the previous exercise is available in your workspace.
