what is not notable about us residents’ support for remaining a world leader in space exploration?
options:
it is shared across generations and political parties.
it is more common among democrats.
it has increased significantly over time.
it is more common among republicans.

Explanation:

The text states "This sentiment is shared equally across generations and among Republicans and Democrats." So the option "It has increased significantly over time" is not supported by the text, as there's no mention of an increase over time. The other options relate to being common among groups (which is supported), but the question asks what is NOT notable. So the option about increasing over time is not a notable aspect here.

Answer:

It has increased significantly over time
