Answer:
You have no answer choices, but I hope that this helps with you writing your answer.
1. People have seen it and when we have documentation of eyewitness accounts, people believe what other people swear that they saw.
2. Sonar has been used to "see" the bottom of the lake/sea floor. They claim that they cannot see it with the naked eye due to all of the stuff on the bottom of the lake, but sound waves have been used to "prove" Nessie exists.
3. Some say that Nessie is a plesiosaurus. Maybe Nessie just did not evolve like the other plesiosaurs. They died out a long time ago.
Explanation:
If you see Nessie, you would believe too.
