Which sentence demonstrates the correct usage of a semicolon?
next month i am planning a trip to the beach; which is my favorite spot to vacation.
next month i am planning a trip to the beach; the beach is my favorite spot to vacation.

The second one because since the first one has which. Which is a conjunction so it can be a compound sentence.

A semicolon is a punctuation mark (;) indicating a pause, typically between two main clauses, that is more pronounced than that indicated by a comma.

I believe the answer to your question is "Next month I am planning a trip to the beach; the beach is my favorite spot to vacation." It uses two clauses in both sentences and it uses a semicolon to separate both of them.

I hope this helps you in your studies and have a great day!

- "the die is cast; i have consented to return if we are not destroyed. thus are my hopes blasted by cowardice and indecision; i come back ignorant and disappointed. it requires more philosophy than i possess to bear this injustice with patience. i have lost my hopes of utility and glory; i have lost my friend."

the correct order is:

you're your own worst enemy:

they're going to say what they say, but

their opinions aren't holding you

back. it's your self-defeatist

attitude that's keeping your work

from getting its due.
