Teacher: Now, understand the problem? Solve this instance: Question: In what country is the Lambert St. Louis International Airport located? Passage 1:The Dhoom series began with the release of Dhoom in 2004. The film became a commercial box office hit and received generally positive reviews from audiences, but not so much from critics. As a result, producer Yash Chopra announced plans for a sequel, titled Dhoom 2: Back in Action. John Abraham, portrayer of Kabir Sharma, the villain of the predecessor, was eliminated from the sequel because Chopra did not want Dhoom 2 to repeat the stories featured in its predecessor. Instead, Hrithik Roshan and Aishwarya Rai were introduced into the franchise as the sequel's main villains. Aishwarya Rai's character was summarised as Catwoman, a female fictional comic book femme fatale or anti-hero . Rai stated, "All I can tell you is it would be nothing like anything you've seen me do before." Producer Aditya Chopra told Rai to lose weight after she gained it for her role in 2004's Bride & Prejudice. Yash Chopra stated, "But yes, the role does require Aishwarya to convey oodles of sensuality. She has asked for a couple of months to get into shape. We (at Yash Raj Films) are very clear about every character in every script and what's required of the actors. Before Dhoom, Esha Deol was specifically briefed about the look and the attitude she needed to cultivate. She readily agreed, and look at what Dhoom did to her career!" Roshan also lost twelve pounds of weight at Aditya Chopra's request. With the exception of Abraham and Esha Deol, all of the other main actors in Dhoom were hired again for Dhoom 2.
 Passage 2:The Red Line MetroLink alignment begins at Lambert St. Louis International Airport, making stops at the main and east terminal stations. It then proceeds through Kinloch before making a stop in North Hanley near Bel-Ridge. It makes 2 stops (UMSL North & South stations) at the University of Missouri St. Louis located in Normandy. After departing UMSL-North Station, the trains divert south onto the former Wabash/Norfolk & Western Railroad's Union Depot (U.D.) line that once brought passenger trains from Ferguson to Union Station. It further follows into 2 stops in Pagedale on St. Charles Rock Road and Wellston on Plymouth St., before crossing the St. Louis City/County boundary line at Skinker Boulevard; and making a stop at Delmar Boulevard, serving the popular Delmar Loop and located just below the original Wabash Railroad's Delmar Station building. The Red Line meets up with the Blue Line at the Forest Park-DeBaliviere station. From this station to the Fairview Heights station in Illinois, it creates the Shared Alignment track with the Blue Line. It terminates in Shiloh next to the Scott Air Force Base and close to the Mid-America Airport in Mascoutah.
