根据短文理解，选择正确答案。
Some people love going to museums，while others absolutely hate it and would rather stay at home，enjoying their favorite TV shows．Increasingly，museums are being seen as outdated and boring by today's youngsters．I have just returned to the UK after travelling around the USA． While there，I visited lots of museums I must say，museums are typically educational, either to develop knowledge gained at school in particular subjects，or to enhance knowledge of other cultures
In Chicago，we visited the world-famous Art Institute of Chicago．It was filled with paintings，drawings and sculptures by a huge variety of artists，such as Picasso，Monet，Matisse and Dali．
There was a mixture of traditional and modern art，including colorful stained glass windows and abstract art．
When we were in Washington D． C． ，we visited a few of the Smithsonian museums．These are all free to visit-which is great if you just want to see a few things，and not spend all day inside．
The Air and Space Museum was particularly good：it had lots of aircrafts and rockets on display，interesting information and also some interactive parts．We also went to the National U．S．Holocaust（纳粹大屠杀）Memorial Museum．Naturally，it was sad to read about the horrors of this tragedy which affected so many people in World War II．However，it was also incredibly interesting to read the stories of those who survived the Holocaust，as well as those who helped others．
Last but not least，I also found the 9/11 Memorial and Museum to be of great interest．This museum is dedicated to those who lost their lives，as well as their families，when the Twin Towers in New York City were attacked by terrorists in 2001It tells you how the terrorists planned the attack，how they hijacked the planes，and ultimately what happened as a result of their actions．Surviving pieces of the towers are shown in the museum，alongside damaged fire engines．It was a truly thought-provoking visit，which made me value my own life that little bit more．
I think museums play an important role in preserving artifacts of historical importance for future generations．Whatever your interests，there is likely to be a museum for you．You can visit waxwork museums to see models of your favorite celebrities（and get photos with the Queen！），science museums for a more hands-on，interactive visit and so much more！Best of all，if you're ever in the UK，many of them are free！
