Here is a premise:
Four decades later, Penderecki has joined the ranks of those who renounce the achievements of his generation; Berio remains unabashedly highbrow and staunchly atonal, a true avant-gardist.

Here is a hypothesis:
Fourty years later, Penderecki decided to open a cafe.

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