Answer:
Hey Isabella,
How's everything at your end? I hope y'all are doing great! <3 Today I and my family went on a luxuriant dinner, of course, I had to share with you everything! We had steak and then we went to the cinema! My family is honestly so extraordinarily stunning! I would love for you to come to my house and meet my family! :)
much love, (your name).
I believe it is C. Try and think about where you would naturally pause, you wouldn't say "Tourists in Mexico *pause* enjoy eating the rich, delicious food."
Uttering words in a low tone. Like if talking by to themselves.
The boxed words are a compound subject.
In a sentence talking about people, the people are subjects of that sentence. Subjects are basically what is being talked about.
Because there are two people being talked about, Bob and Al, the subjects are counted as one, or compounded. This just means that you read the sentence as [Bob and Al] instead of [Bob] and Al.
Compound verbs follow the same concept, but for action words. For example, “to sing and to dance”. However, in this case since the boxed words are subjects, they are a compound subject.
