Subject of the issue

Got unknown question type when downloading the course mentioned below.

Your environment

• Operating System (name/version): macOS 10.13.5
• Python version: 2.7.10
• coursera-dl version: 0.11.4

Steps to reproduce

• Is the problem happening with the latest version of the script? I think so, I just upgraded through pip, I have 0.11.4

• Do you have all the recommended versions of the modules? See them in the file requirements.txt. I think so, I just upgraded through pip, I have 0.11.4

• What is the course that you are trying to access? https://www.coursera.org/learn/linear-algebra-machine-learning/home/week/1 Quiz appears to be exploring-parameter-space

• What is the precise command line that you are using (don't forget to obfuscate your username and password, but leave all other information untouched). $ coursera-dl --debug --download-quizzes --download-notebooks -u dgrogan@XXXcom -p XXXX -sl en linear-algebra-machine-learning

• What are the precise messages that you get? Please, use the --debug option before posting the messages as a bug report. Please, copy and paste them. Don't reword/paraphrase the messages.

Expected behaviour

Download all questions on all quizzes, I think.

Actual behaviour

I haven't looked yet to see what actually downloaded, but I imagine these unknown ones did not :)
