Question

read the text.
even before the start of world war ii, several countries had developed cipher systems (secret codes) for top - secret communication. for example, germany developed enigma, a family of cipher machines, to conceal important messages. in 1932, the polish cipher bureau was able to overcome enigma and break the code. in 1941, the germans introduced a new cipher system, the lorenz sz40/42, to frustrate their opponents intelligence gathering. the british eventually developed colossus, some of the first electronic computers, to break the code. meanwhile, the japanese developed a cipher machine that americans called purple. the u.s. military took on the challenge of deciphering purple, and the army signal intelligence service eventually broke the code.
match the problems with their solutions.
colossus broke the code. the polish cipher bureau broke the code.
the u.s. army signal intelligence service broke the code.
problem solution
the german military used enigma.
the german military used lorenz sz 40/42.
the japanese military used purple

Explanation:

• For "The German military used Enigma", the text says "In 1932, the Polish Cipher Bureau was able to overcome Enigma and break the code".
• For "The German military used Lorenz SZ40/42", it states "The British eventually developed Colossus...to break the code".
• For "The Japanese military used Purple", it mentions "the U.S. military took on the challenge of deciphering Purple, and the Army Signal Intelligence Service eventually broke the code".

Answer:

• The German military used Enigma → The Polish Cipher Bureau broke the code.
• The German military used Lorenz SZ40/42 → Colossus broke the code.
• The Japanese military used Purple → The U.S. Army Signal Intelligence Service broke the code.
