Are you trying to turn your document into a MLA format or are you trying to cite your sources using MLA format? There is a website I use that is very helpful
The plural possessive form of <em>women</em> is women's. This is because women is already the plural form of woman and to make it possessive you simply need to add the apostrophe "s".
The word with a negative connotation is discouraging.
When someone is discouraged, they are dispirited, disheartened, and with a lack of enthusiasm; this has a negative implication.
All other options have positive connotations, except maybe bulb, which is pretty neutral.
I hope this helps you!
But none of the sentences are called capitalized though
