Answer:
The answer is the hindshight bias.
Explanation:
This bias takes place when a person believes an event was more predictable after it already has occured. For this reason, it is also called the "knew-it-all-along" bias.
The hindsight bias might cause memory distortions in people: it's possible that they reinterpret some of their memories in order to fit their perceived prediction.
George Washington offered to lead the men in the Battle of Boston.
The answer is 3) From calls made to one hundred randomly generated telephone numbers, people replied to a question about television shows they watch
This is because the people questioned were completely chosen at random and were asked about something they might or might know much about. This is easily the least biased option.
However, other surveys were not biased, e.g. asking heart surgeons about children's diet or asking ex-employees of The World of Baseball Bookstore about the importance of baseball.
These are not a random selection and might not actually provide accurate results.
The Delian League was formed so that the Greek city-states fight together against the Persians.
Explanation:
The Delian League was formed by the suggestion of Athens. The purpose of Athens was to fight the Persians even after the war officially ended. The Greek city-states accepted the proposal of Athens and they created the Delian League.
Athens though, despite being the one that initiated the formation, was actually the one that caused the crumbling of the Delian League. The reason was that Athens started to use the funds of the Delian League for its own purposes, so once the other city-states found out about this they got into conflict with Athens. Things escalated when Sparta got involved, with a war between Sparta and Athens emerging, known as the Peloponnesian War, which put an end to the Delian League.
