Question 1

2001: A Space Odyssey is broken into four sections, three of which are introduced by title cards. The third and fourth sections are "Jupiter Mission" and "Jupiter and Beyond the Infinite" (The second section is titled "TMA-1" in the screenplay, but this is never shown on screen). What is the exact four word name for the first sequence, set in the distant past in an arid region of Africa, which extends from the start of the film until the dramatic jump forward to 1999?
