Question

9:37am - 11:02am
at 9:42am, the federal aviation authority (faa) took what drastic steps?
evacuation of the white house
released the names of suspected hijackers to the public
canceled all future flights
grounded all flights over or bound for the continental u.s.

Explanation:

The Federal Aviation Authority (FAA) grounded all flights over or bound for the continental U.S. as a drastic step at 9:42 am on September 11, 2001, in response to the hijackings and security threats. Evacuating the White House was not an FAA - related action. Releasing hijackers' names was not done by the FAA at that time. Canceling all future flights is too broad; the action was specifically about grounding flights over or bound for the continental U.S.

Answer:

D. Grounded all flights over or bound for the continental U.S.
