I'm taking a test and have to guess the right answer to the question after the article.
Article: Hadrian's Wall
Hadrian's Wall was built, beginning in 122 AD, to keep Roman Britain safe from attacks from the Picts. The wall, starting from the North Sea to the Irish Sea (from the Tyne to the Solway), is about 73 miles long, 10 feet wide, and 15 feet high. In addition to the wall, the Romans built a system of small forts  housing up to 60 men every Roman mile along its whole length, with e towers very 1/3 Roman mile. 16 larger forts holding from 500 to 1000 soldiers were built into the wall, with large gates on the north face.

The Berlin Wall
The Berlin Wall was the physical boundary between West Germany and East Germany. The Berlin Wall was built in the dead of night in 1961 and for 28 years kept East Germans from escaping to the West. Its destruction (in 1989) was celebrated around the world.
Conwy's Town Walls
Conwy's Town Walls are an ancient defensive   project around the town of Conwy in North Wales. The walls were built between 1283 and 1287. They are 1.3 kilometers long and include 21 towers and three gate houses. The project was completed by large quantities of workers and cost around PS15,000. Today the walls form part of the UNESCO world heritage site .
Question: People around the world celebrated the destruction of  _  .
Options: A: the Israeli West Bank barrier
B: the Berlin Wall
C: Conwy's Town Walls
D: Hadrian's Wall
B
The Berlin Wall was built in 1961 and separated West Germany from East Germany. It kept the people of East Germany trapped inside, unable to escape their communist government. The wall stood until 1989 when a peaceful revolution led to its destruction by citizens eager for freedom. This event marked the beginning of the end of communism in Europe and cheering crowds worldwide celebrated this victory over tyranny .
Thus B is correct!.
