Martians or Aliens, oppose to Zombies and other monsters, cause a unique fear because of the fact that outer space scares us. I mean, why shouldn't it? Space is a cold desolate place bigger than we could possibly imagine, whereas the earth, where we live, is mostly explored. That's not even including all the rumors about Alien cover-ups by the government.
"B. The only scary part of deep-sea fishing <span>happened when the fish was pulled onto the boat" is the only sentence that has a passive verb (was pulled) since this verb is happening TO the fish instead of the fish "doing" the verb to something else. </span>
For me, this situation depicts the real life situation of every individual. The giant human maze represents life's struggle and problems which is faced by every person in his day to day activities. This can never be taken away from human existence. The challenges will always be a part of everybody's lives.
