How do I insert Adobe Acrobat pages into a Powerpoint Presentatio.

[Troubled]

I am trying to create a powerpoint presentation using some slides from an
Adobe Acrobat document. I am able to insert as an object and select the adobe
document but only the first page of the adobe document shows up. How do I
import all the rest of the pages (29 slides in all). I have already tried
opening the adobe doc. with Powerpoint but it is too big to display
