Read the following paragraph and identify the Object of Prepositions: Mark Twain loved to brag about his hunting and
fishing exploits. He once spent three weeks fishing in the Maine woods, regardless of the fact that it was the state's closed season for fishing. Relaxing in the lounge car of the train on his return journey to New York, his catch iced down in the baggage car, he looked for someone to whom he could relate the story of his successful holiday.

can you elaborate on what the question asks?

i cannot see a paragraph to answer the question

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.
