GRE Analogy Example

San Francisco

Compare Boston to San Francisco, both cities have ports, you can not say they are the same due to they own ports, think about the culture, industries ..., they are different. Think further to reveal characteristics of the two objects.

Two objects (such as : two countries, cities, companies, universities, issues ... ) have one or
two in common doesn't mean they are the same in other aspects.

Inside Hubble's Final Mission

As a NASA Astronaut, John Herrington has journeyed into space aboard the Space Shuttle and space walked at the International Space Station. On Inside Hubble's Final Mission he takes the cameras of National Geographic to give you a rare behind the scenes look at the people places and things that have prepared the crew and the Space Shuttle Atlantis for our final voyage to the Hubble Space Telescope. Together we will guide you on a remarkable journey into the heart of NASA's Kennedy Space Center, the home of the Space Shuttle fleet, to the training sessions and simulators at the Johnson Space Center in Houston, TX.
