"When you put the last touches on our project, can you send it too Mr. Jones
and me?" Harriet asked Amy. Amy
agreed but she was frustrated because
she felt she had done the majority of the
work herself this always seemed to
happen to
her. There has been
many times when Amy
chose to work alone
on projects for this
reason. Which of the helping verbs need to be switch from singular to plural??

21 balloons is the story of professor william sherman's travels.

in 1883, he set off from san francisco for a balloon ride over the pacific and was found a month later floating with 21 balloons in the atlantic ocean. this seemed an astounding feat and everyone wanted to know what had happened.    

professor sherman was loyal, however, and said he would tell his tale first to the western american explorers club in san francisco, of which he was a member. this built up suspense for several chapters before he began to tell of the wonders of his adventures and the amazing island of krakatoa, an island which had just been blown up by a volcano.  

the residents of krakatoa are all millionaires who live under a "gourmet government" of their own devising. we get to see all the incredible adventures that creative people with unlimited resources would create according to the author.
