Problem: The Commercial Port of Guam is the island's lifeline because most products must be shipped into Guam for consumers. It receives the weekly calls of the Hawaii-based shipping line Matson, Inc. whose container ships connect Guam with Honolulu, Hawaii, Los Angeles, California, Oakland, California and Seattle, Washington. The port is also the regional transhipment hub for over 500,000 customers throughout the Micronesian region. The port is the shipping and receiving point for containers designated for the island's U.S. Department of Defense installations, Andersen Air Force Base and Commander, Naval Forces Marianas and eventually the Third Marine Expeditionary Force.
What is considered to be the lifeline of Guam?
The answer is the following: The Commercial Port

Problem: During the board process an officer's record is reviewed by a selection board at the Air Force Personnel Center at Randolph Air Force Base in San Antonio, Texas. At the 10 to 11 year mark, captains will take part in a selection board to major. If not selected, they will meet a follow-on board to determine if they will be allowed to remain in the Air Force. Promotion from major to lieutenant colonel is similar and occurs approximately between the thirteen year (for officers who were promoted to major early "below the zone") and the fifteen year mark, where a certain percentage of majors will be selected below zone (i.e., "early"), in zone (i.e., "on time") or above zone (i.e., "late") for promotion to lieutenant colonel. This process will repeat at the 16 year mark (for officers previously promoted early to major and lieutenant colonel) to the 21 year mark for promotion to full colonel.
The promotion process repeats when for officers promoted early in the USAF?
The answer is the following: 16 year mark

Problem: Further developments include new lignin glue applications, recyclable food packaging, rubber tire replacement applications, anti-bacterial medical agents, and high strength fabrics or composites. As scientists and engineers further learn and develop new techniques to extract various components from wood, or alternatively to modify wood, for example by adding components to wood, new more advanced products will appear on the marketplace. Moisture content electronic monitoring can also enhance next generation wood protection.
Instead of rubber, what important part of a car might someday be replaced by components of wood?
The answer is the following: tire

Problem: Matrix groups consist of matrices together with matrix multiplication. The general linear group GL(n, R) consists of all invertible n-by-n matrices with real entries. Its subgroups are referred to as matrix groups or linear groups. The dihedral group example mentioned above can be viewed as a (very small) matrix group. Another important matrix group is the special orthogonal group SO(n). It describes all possible rotations in n dimensions. Via Euler angles, rotation matrices are used in computer graphics.
What groups combine matrices with matrix multiplication?
The answer is the following:
Matrix groups
