Answer:
A) Alter its own spending, taxes, and/or the amount of money in circulation.
Explanation:
In situations of economic warming and inflation the government can act to influence citizens' spending to cool down economic activity to lower inflation. Inflation is a monetary phenomenon caused by excess currency in the economy. Thus, the government can reduce its spending, because it is an important player, which makes government consumption has a significant weight in economic warming. In addition, the government can take steps to curb citizen consumption through restrictive policies such as raising taxes. Finally, the government may sell government bonds to wipe out the monetary base. When the government sells bonds, people stop consuming at present to earn future income from public bonds. Thus, the government causes the money in circulation to decrease.
In the years from 1900 to the present, life expectancy in the United States has drastically increased.
The tremendous increase in life expectancy during the last century may be the greatest human achievement.
In the 110 years between 1900 and 2010, the United States' life expectancy at birth increased from 47.3 to 78.7 years (Centers for Disease Control and Prevention/National Center for Health Statistics [CDC/NCHS], 2012, 2013). Declines in infectious diseases and fatalities disproportionately among the young caused this longer lifespan. After infectious diseases accounted for the majority of deaths, the leading causes of mortality were cancer and cardiovascular diseases. In the second half of the 20th century, these then became the focus of science and medicine.

Avery and his group used enzymes to degrade DNA, RNA and protein in 3S bacteria. DNA from those cells was then tested to see if it can convert 3R cells into 3S cells. It was observed that 3R cells were converted to 3S cells except when the DNA was destroyed. Thus, DNA was pin-pointed as the transforming agent.
