Original sentence: A cable car can zoom you up the mountain — quick, easy, and the scenery is awesome!
Best corrected sentence (simple): A cable car can zoom you up the mountain quickly and easily, and the scenery is awesome!
Another good option (two short sentences): A cable car can zoom you up the mountain. It's quick and easy, and the scenery is awesome!
Why we change it:
- We use quickly and easily because these are adverbs. Adverbs tell how something is done (the cable car zooms quickly), while adjectives (like quick, easy) describe nouns.
- The phrase "and the scenery is awesome" is a full idea on its own, so we either join it with a comma and and, or make a new sentence. Both ways are correct.
- The long dash is okay, but for a 7-year-old sentence, commas or a new sentence are easier to read.
Short tip: To say how something happens, use words that end with -ly (like quickly). If you want, you can also make two short sentences — that often reads clearer for young readers.
