what is the simple subject in the following sentence? The space shuttle service have made travel to the international space station convenient and possible. A.travel B.possiible C.station D.shuttles
The answer should be The Space Shuttle Service. I'm going to say to go with answer D. because the shuttles are the thing doing something in the sentence. What are they doing? Making it convenient to travel to the international space center.
The subject of the sentence is the shuttle, because gramatically it is the subject of the sentence (linked to a verb) and by interpretation, it is also the main topic of the sentence.
