The problem: Answer a question about this article:
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.
When does promotion from major to lieutenant colonel in the USAF typically occur?
****
The answer: thirteen year

The problem: Answer a question about this article:
In absolute terms, the planet has lost 52% of its biodiversity since 1970 according to a 2014 study by the World Wildlife Fund. The Living Planet Report 2014 claims that "the number of mammals, birds, reptiles, amphibians and fish across the globe is, on average, about half the size it was 40 years ago". Of that number, 39% accounts for the terrestrial wildlife gone, 39% for the marine wildlife gone, and 76% for the freshwater wildlife gone. Biodiversity took the biggest hit in Latin America, plummeting 83 percent. High-income countries showed a 10% increase in biodiversity, which was canceled out by a loss in low-income countries. This is despite the fact that high-income countries use five times the ecological resources of low-income countries, which was explained as a result of process whereby wealthy nations are outsourcing resource depletion to poorer nations, which are suffering the greatest ecosystem losses.
What percentage of biodiversity has the planet lost since 1970
****
The answer: 52%

Nevertheless, the government was able to make wide-ranging economic reforms that paid off in dramatically lower inflation and steady growth. The 1994 cease-fire in the Nagorno-Karabakh conflict has also helped the economy. Armenia has had strong economic growth since 1995, building on the turnaround that began the previous year, and inflation has been negligible for the past several years. New sectors, such as precious-stone processing and jewellery making, information and communication technology, and even tourism are beginning to supplement more traditional sectors of the economy, such as agriculture.
Since when has Armenia experienced a positive growth in their economy?
****
The answer:
1995
