Answer:
"As a result" signals a transition that shows a cause-and-effect relationship.
for ex. My brother did not attend school yesterday because he was feeling sick. As a result, he now has to make up an English test he missed.
Explanation:
"On the other hand" is used to contrast two things. ex. I like the color purple, <em>on the other hand</em>, my sister despises it.
"also" is being used to transition to another, similar thing. ex. The store <em>also</em> had those snacks you enjoy, so I bought them.
"before" doesn't always mean it relates two events with a cause/effect relationship. ex. I locked the front door before we left for dinner.
(I can attach the required vocabulary for this question if necessary) Never in my life, (comma with a phrase at the beginning) have I ever doubted my <u><em>confidant</em></u>’s <u><em>fidelity</em></u>, my <u><em>amiable</em></u> husband who has always stood by my side, through my ups and downs, (commas in a series, with coordinate adjectives) when I was <u><em>dejected</em></u>, euphoric, sick, overwhelmed, (he literally knows every possible side of mine, he is really patient with the lunatic me), (commas around parenthetical phrases) and I could never regret being with him. Vocabulary used: confidant, fidelity, amiable, dejected.
