On Tuesday, we featured the ninety-ninth challenge to see how well you knew the Metro system. Here are the answers. How’d you do?

Image 1: 
The first image is West Falls Church. This is one of only two stations with three tracks and two platforms. That was the main clue here. The slanted windows are also fairly unique, though Vienna has these as well.
20 got it right.
Image 2:
The second image shows the view looking up at the artwork at Gallery Place, titled Glory of the Chinese Descendants. This artwork, in the shape of a large fan sits above the H Street entrance.
19 knew it.
Image 3: 
The third picture shows the pedestrian bridge linking Suitland station with the parking garage and the federal office complex there. A few stations have bridges like this, but Suitland's is fairly unique in being open sided. The concrete is also newer, which was another clue.
17 figured it out.
Image 4: 
The fourth image shows the mezzanine at Mount Vernon Square. From the photo, you can identify this as an Arch II station served by the Green, Yellow, and Yellow Rush Plus lines. That narrows it to three possibilities.
18 guessed correctly.
Image 5: 
The final image shows one of the street entrances to Friendship Heights. The northern mezzanine leads to a chamber under Western Avenue with corridors leading to all four corners. This hallway leads to the southwestern corner, and uses the architectural finishes of the development it leads to, though has the standard curved walls and railings typical of other Metro corridors.
16 came to the correct conclusion.
Thanks for playing! We’ll be back in two weeks with our next quiz.
