Answer:
her undeterred devotion to Stephen
Explanation:
A static character is one who does not have many personality traits and who is very simple to describe them, because they are not complex and deep, having only one or two striking characteristics. In Rachel's case, we can say that she is a static character, because her only personality trait is her devotion to Stephen. This is a very important feature of the story, but it is all that Rachel has to offer.
The connection between Mrs. Yang's gardening and Samara's idea to build a park is "Residents agreed that Mrs. Yang would manage the gardens."
Samara realized there were no public spaces for people to relax enjoying nature. When she saw Mrs. Yang gardening and her ability to do such a thing and regarding her experience and knowledge in gardening in Korea, Samara thought it would be a great idea for her to manage the park building and guide other people to help with the community garden.
Sarcasm is an ironic or satirical remark tempered by humor. Mainly, people use it to say the opposite of what's true to make someone look or feel foolish. For example, let's say you see someone struggling to open a door and you ask them, "Do you want help?" If they reply by saying, "No thanks. I'm really enjoying the challenge," you'll know they're being sarcastic. Sarcasm is all about the context and tone of voice, which is why it works better verbally. It's something you'll know when you hear it.
