This question is incomplete, here´s the complete question.
It is only in the past few years that women in the armed services of the United States have been permitted to be active combatants in a battlefield setting. While this has taken place over a number of years and has evolved for a variety of reasons, it is also reasonable to suggest that it has happened in part because of:
a. increased militarization worldwide.
b. greater global threat levels.
c. increased terrorist activity.
d. a shortage of qualified male soldiers.
Answer: a. increased militarization worldwide.
Explanation:
Women have been allowed to serve as an official part of the U.S. military in noncombat positions after Congress founded the Army Nurse Corps (1901). Women were also radio operators, logistical personnel and even helicopter pilots and tank technicians.
Increased militarization worldwide has expanded the United State´s female participation in combat since the early 1990s, when women were allowed to work in aviation and naval combat, and especially since 2016, when they were allowed to work all ground combat jobs.
