Problem: Houston:

Houston is recognized worldwide for its energy industry—particularly for oil and natural gas—as well as for biomedical research and aeronautics. Renewable energy sources—wind and solar—are also growing economic bases in the city. The Houston Ship Channel is also a large part of Houston's economic base. Because of these strengths, Houston is designated as a global city by the Globalization and World Cities Study Group and Network and global management consulting firm A.T. Kearney. The Houston area is the top U.S. market for exports, surpassing New York City in 2013, according to data released by the U.S. Department of Commerce's International Trade Administration. In 2012, the Houston–The Woodlands–Sugar Land area recorded $110.3 billion in merchandise exports. Petroleum products, chemicals, and oil and gas extraction equipment accounted for approximately two-thirds of the metropolitan area's exports last year. The Top 3 destinations for exports were Mexico, Canada, and Brazil.

Besides oil and gas, what is Houston known for?

Problem: Northwestern's School of Communication has been especially fruitful in the number of actors, actresses, playwrights, and film and television writers and directors it has produced. Alumni who have made their mark on film and television include Ann-Margret, Warren Beatty, Jodie Markell, Paul Lynde, David Schwimmer, Anne Dudek, Zach Braff, Zooey Deschanel, Marg Helgenberger, Julia Louis-Dreyfus, Jerry Orbach, Jennifer Jones, Megan Mullally, John Cameron Mitchell, Dermot Mulroney, Charlton Heston, Richard Kind, Ana Gasteyer, Brad Hall, Shelley Long, William Daniels, Cloris Leachman, Bonnie Bartlett, Paula Prentiss, Richard Benjamin, Laura Innes, Charles Busch, Stephanie March, Tony Roberts, Jeri Ryan, Kimberly Williams-Paisley, McLean Stevenson, Tony Randall, Charlotte Rae, Paul Lynde, Patricia Neal, Nancy Dussault, Robert Reed, Mara Brock Akil, Greg Berlanti, Bill Nuss, Dusty Kay, Dan Shor, Seth Meyers, Frank DeCaro, Zach Gilford, Nicole Sullivan, Stephen Colbert, Sandra Seacat and Garry Marshall. Directors who were graduated from Northwestern include Gerald Freedman, Stuart Hagmann, Marshall W. Mason, and Mary Zimmerman. Lee Phillip Bell hosted a talk show in Chicago from 1952 to 1986 and co-created the Daytime Emmy Award-winning soap operas The Young and the Restless in 1973 and The Bold and the Beautiful in 1987. Alumni such as Sheldon Harnick, Stephanie D'Abruzzo, Heather Headley, Kristen Schaal, Lily Rabe, and Walter Kerr have distinguished themselves on Broadway, as has designer Bob Mackie. Amsterdam-based comedy theater Boom Chicago was founded by Northwestern alumni, and the school has become a training ground for future The Second City, I.O., ComedySportz, Mad TV and Saturday Night Live talent. Tam Spiva wrote scripts for The Brady Bunch and Gentle Ben. In New York, Los Angeles, and Chicago, the number of Northwestern alumni involved in theater, film, and television is so large that a perception has formed that there's such a thing as a "Northwestern mafia."
