I'm here learning out my ged book... and I'm learning sentence structure, but I cant seem to get this one question right... the most effective revision of a sentence would include which group of words?and also, the most effective combination of sentences would include which group of words?I just cant them right when I do the practice test... I just don't really understand it... its not coming to me... can I get some help on to reconizing it in a group of sentences...
