1.Why is it a good idea to start a research project with a research question? It helps you focus your research so that you stay interested in it and find sources more easily.

It helps remind you to use lots of different kinds of sources for your project or paper.

It helps you practice writing questions so that you’ll be ready if you have to interview someone.

It helps you keep your topic more broad so that you have lots of directions to go in.

The correct answer is A or it helps you focus your research so that you stay interested in it and find sources more easily.

i believe the answer is: b. mr. head had a long, tube-like face with a rounded open jaw and a short depressed nose.

this is because in the un-revised sentence it said that mr. heads face was long and tube-like, and he had a rounded open jaw. this is not a very grammatically correct because of how it seems to drag on with the and, replaced with, with, makes it sound more fluent in the description.
