I have a few questions.

"....test scanner options (a standard scanner and HoverCam) recommended by "the" Columbia Light House."

Q.  Do not need to use "the"?  That is the the company name.

Ms. B. had difficulty navigating to the Gmail login/password screen. In addition, she did not recall her password, which was normally saved on her computer at home.
Q.  I added which was normally saved on her computer at home.  Should I use "because"?  Please advise.

A ZoomText Magnifier/Reader may be suitable for Ms. B. than Jaws, since Jaws requires memorizing more keystroke combinations unless her eye condition becomes worth.

Q.  I am not sure what I should use to make it clear.  As long as her eyes stays with the same condition (she can see some with her one eye), ZoomText software is O.K. to magnify and see whatever on the screen.  Jaws sofware is suitable for people who are totally blind and who is able to memorize many keystroke combinations. I am not sure if she can memorize all combinations. (Jaws is not a good software to use as of today and is not certain that she can use it later.  (senior above 70 years old). 

Please advise.
