Here is a premise:
Time criticizes Seymour Hersh's controversial JFK book, The Dark Side of Camelot . Hersh's juicy stories are recycled from other books, the magazine says, and sources for damaging accusations are dubious or misquoted.

Here is a hypothesis:
Hersh wrote a book about Nixon.

Is it possible to conclude that if the premise is true, then so is the hypothesis?
no
