Using x omitting "that" Hi, there Which of THESE sentences is right? "At the airport, there are many lines. There's the line for your flight, the line to get a coffee, and the line to get the headphones you forgot at home but are essential to your flight" or "At the airport, there are many lines. There's the line for your flight, the line to get a coffee, and the line to get the headphones you forgot at home but THAT are essential to your flight" "A sentence then must express some kind of meaning that does not clearly reside in its nouns and verbs but embraces the entire combination" or "A sentence then must express some kind of meaning that does not clearly reside in its nouns and verbs but THATembraces the entire combination" With or without "that"? Thank you!
