#feedback for the last few lessons, the speed of JY's speech has intermittently gone full force, approximately 9000 times the normal speed.

I apologize in advance if this has already been asked/answered:

Are other similar drills available on the website? I want to make sure I have a firm grasp on subject/predicate/object/modifier.

I think what threw me when deciding between two choices was that C used "all". I thought we should be leary of answer choices that utilized this type of wording (eg: all, none, etc). Did I misunderstand this advice? Are there only specific types question stems in which we should avoid all or nothing options?
