Answer to Question 1

Telescopes in space and on Earth's surface have revealed that quasars are often surrounded by hazy features whose spectra resemble those of normal galaxies. Evidently, quasars are located in galaxies. In addition, radio telescopes have revealed that some quasars are ejecting jets and inflating radio lobes. The evidence is now overwhelming that quasars are the active cores of very distant galaxies.

Answer to Question 2

True
