Answer to Question 1

TRUE

Answer to Question 2

Starburst galaxies are filled with star-forming molecular clouds, which contain dust grains that absorb most of the visible light produced by the young stars. This radiation heats the dust grains to very high temperatures, and they re-emit all the absorbed energy as infrared light.
