Alejandra has come across a section in her physics textbook writing that she does not understand. She has tried asking her teacher and her classmates for help, but no one seems to be able to explain it to her in a way that she can understand. Alejandra is starting to feel frustrated and is about to give up when she comes across a website that has a step-by-step explanation of the concept.
She is finally able to understand the concept and is even able to apply it to a problem that she was having trouble with. Alejandra is relieved and grateful that she was able to find the help that she needed.
