Question

why were the british able to win the battle of britain?
their radar equipment was effective.
their leader urged them to keep fighting germany.
their air force was more determined and powerful than germany’s.
their spies kept them informed by sending secret messages.

Explanation:

The Battle of Britain relied heavily on air defense, and Britain's early and effective radar network (Chain Home) was a key advantage. It allowed the Royal Air Force to detect incoming German raids early, conserve resources, and intercept attackers efficiently. While leadership resolve mattered, radar was a critical, unique tactical asset. The RAF was not more powerful numerically than the Luftwaffe, and spy intelligence was not the primary factor in the air battle's outcome.

Answer:

A. Their radar equipment was effective.
