The river crossed by the famous London Bridge.

• A. Nile
• B. Thames
• C. Seine
• D. Tiber

Answer: (B)

The key idea is knowing which river runs through London and is linked to the name London Bridge. The famous London Bridge crosses the River Thames, the major river that flows through southern England and through central London. The other rivers—Nile in Africa, Seine in Paris, and Tiber in Rome—do not pass through London. So the river associated with London Bridge is the Thames.
