Paragraph- Sent 1: Sometimes a full Moon moves through Earths shadow.

Sent 3: During a total lunar eclipse, the Moon travels completely in Earths umbra.
Sent 4: During a partial lunar eclipse, only a portion of the Moon enters Earths umbra.
Sent 5: When the Moon passes through Earths penumbra, it is a penumbral eclipse.
Sent 6: Since Earths shadow is large, a lunar eclipse lasts for hours.
Sent 7: Anyone with a view of the Moon can see a lunar eclipse.
Sent 8: So unlike a solar eclipse, it doesnt get dark on Earth.
Sent 9: Instead it gets dark on the Moon.
Sent 10: Partial lunar eclipses occur at least twice a year, but total lunar eclipses are less common.
Sent 11: The Moon glows with a dull red coloring during a total lunar eclipse. 
Question: During a lunar eclipse, does the earth or moon get dark?.

question:
Paragraph- Sent 1: According to the radar reconstruction, American 77 reemerged as a primary target on Indianapolis Center radar scopes at 9:05, east of its last known position.
Sent 2: The target remained in Indianapolis Center's airspace for another six minutes, then crossed into the western portion of Washington Center's airspace at 9:10.
Sent 3: As Indianapolis Center continued searching for the aircraft, two managers and the controller responsible for American 77 looked to the west and southwest along the flight's projected path, not east-where the aircraft was now heading.
Sent 4: Managers did not instruct other controllers at Indianapolis Center to turn on their primary radar coverage to join in the search for American 77.
Sent 5: In sum, Indianapolis Center never saw Flight 77 turn around.
Sent 6: By the time it reappeared in primary radar coverage, controllers had either stopped looking for the aircraft because they thought it had crashed or were looking toward the west.
Sent 7: Although the Command Center learned Flight 77 was missing, neither it nor FAA headquarters issued an all points bulletin to surrounding centers to search for primary radar targets.
Sent 8: American 77 traveled undetected for 36 minutes on a course heading due east for Washington, D.C. By 9:25, FAA's Herndon Command Center and FAA headquarters knew two aircraft had crashed into the World Trade Center.
Sent 9: They knew American 77 was lost.
Sent 10: At least some FAA officials in Boston Center and the New England Region knew that a hijacker on board American 11 had said "we have some planes."Sent 11: Concerns over the safety of other aircraft began to mount.
Sent 12: A manager at the Herndon Command Center asked FAA headquarters if they wanted to order a "nationwide ground stop."Sent 13: While this was being discussed by executives at FAA headquarters, the Command Center ordered one at 9:25.
Sent 14: The Command Center kept looking for American 77.
Sent 15: At 9:21, it advised the Dulles terminal control facility, and Dulles urged its controllers to look for primary targets.
Sent 16: At 9:32, they found one.
Sent 17: Several of the Dulles controllers "observed a primary radar target tracking eastbound at a high rate of speed" and notified Reagan National Airport.
Sent 18: FAA personnel at both Reagan National and Dulles airports notified the Secret Service. 
Question: Who notified the secret service.
answer:
FAA personnel at Reagan.


question:
Paragraph- Sent 1: Earthquakes seemed to outline a special feature of earth's crust.
Sent 2: Earthquakes let scientists know where the crust was moving.
Sent 3: This led to the discovery that the Earths crust was broken up into regions, or plates.
Sent 4: Earthquakes happen most often along these plate boundaries.
Sent 5: This was evidence that continents can move.
Sent 6: The movements of the plates are called plate tectonics.
Sent 7: The Earths crust is divided into plates.
Sent 8: There are about a dozen large plates and several small ones.
Sent 9: Each plate is named for the continent or ocean basin it contains.
Sent 10: Scientists know he plates are in motion.
Sent 11: They now know the direction and speed of this motion .
Sent 12: Plates dont move very fast.
Sent 13: They move only a few centimeters a year.
Sent 14: This is about the same rate fingernails grow.
Sent 15: So you might wonder, what could cause this motion?
Sent 16: What supplies the energy to cause this change?. 
Question: What do earthquakes tell scientists and what is special about them?.
answer:

Direction of crust movement.
