Could anyone help me? I've been studying a grammar book in English and I just wrote some exercises. Is it right these exercises? *Among and Between* 1) The king was among the crowd. 2) You can take a sit between that woman and that man. 3) Your cup of coffee is that one which is between the carton of juice, the can of soda and a jar of water. *Until and Throughout* 4) Obama is the president of the United States until December 2016. 5) The boy has been sleeping throughout the class. Thanks a lot!
