Answer to Question 1

(a) We see many quasars with high redshifts, but none with blueshifts. (b) Images show that quasars are embedded in the centers of extremely distant galaxies. (c) Some quasars have been observed to be members of distant galaxy clusters. (d) There are examples of nearby active galaxies (Seyfert galaxies) that look a lot like quasars except that they are less powerful.

Answer to Question 2

FALSE
