Problem: Anti-aircraft warfare:

The US ended World War I with two 3-inch AA guns and improvements were developed throughout the inter-war period. However, in 1924 work started on a new 105 mm static mounting AA gun, but only a few were produced by the mid-1930s because by this time work had started on the 90 mm AA gun, with mobile carriages and static mountings able to engage air, sea and ground targets. The M1 version was approved in 1940. During the 1920s there was some work on a 4.7-inch which lapsed, but revived in 1937, leading to a new gun in 1944.

What year was the M1 version approved?
---
A: 1940

Problem: Arnold Schwarzenegger:

Schwarzenegger was born with a bicuspid aortic valve, an aortic valve with only two leaflets (a normal aortic valve has three leaflets). Schwarzenegger opted in 1997 for a replacement heart valve made of his own transplanted tissue; medical experts predicted he would require heart valve replacement surgery in the following two to eight years as his valve would progressively degrade. Schwarzenegger apparently opted against a mechanical valve, the only permanent solution available at the time of his surgery, because it would have sharply limited his physical activity and capacity to exercise.

What word describes an aortic valve with two rather than three leaflets?
---
A: bicuspid

Problem: Canadian Armed Forces:

The Armed Forces' 115,349 personnel are divided into a hierarchy of numerous ranks of officers and non-commissioned members. The governor general appoints, on the advice of the prime minister, the Chief of the Defence Staff (CDS) as the highest ranking commissioned officer in the Armed Forces and who, as head of the Armed Forces Council, is in command of the Canadian Forces. The Armed Forces Council generally operates from National Defence Headquarters (NDHQ) in Ottawa, Ontario. On the Armed Forces Council sit the heads of Canadian Joint Operations Command and Canadian Special Operations Forces Command, the Vice Chief of the Defence Staff, and the heads of the Royal Canadian Navy, the Canadian Army, the Royal Canadian Air Force and other key Level 1 organizations. The sovereign and most other members of the Canadian Royal Family also act as colonels-in-chief, honorary air commodores, air commodores-in-chief, admirals, and captains-general of Canadian Forces units, though these positions are ceremonial.

Who is the highest ranking member of the Armed Forces?
---
A:
the Chief of the Defence Staff
