Answer to Question 1

FALSE

Answer to Question 2

A starburst might end by simply using up all the available gas to form stars or it may end by the combined effect of many supernovae driving a wind that blows all the gas out of the galaxy. The galaxy will then age, with old stars dying but no new stars forming until enough gas has accumulated, either from the remnants of old stars or by gas falling back into the galaxy. The halt in star formation can be billions of years.
