How does your answer say correct and someone else says the same im confused

the statement flat characters usually only have one trait that is developed in their story lines is true.

the message which is being conveyed is that if a person does not have the qualified skills to be an writer then he should not and if he becomes then just leave it away..

i think this is it plz check

martians or other types of aliens represent a unique fear as opposed to zombies. vampires and other types of monsters.   in most sci-fi stories, aliens come from other worlds and have different or more advanced technology.   abductions and experimentation on human bodies that involve these technologies, or the use of these technologies against human beings and the use of unknown "powers", are a type of fear that's different from that of other types of monsters.  

sing because that is what they are doing in the sentence

explanation:

the simple predicate is the main verb in the predicate that tells what the subject does. example: my father fixed the dryer. read each sentence. draw a line under the complete predicate.
