Answer:
I think your answer is D. Accurate calendar systems.
Explanation:
Most of the people working before WW2 was males, with females doing all the house work, and told to "not get any outside jobs". However, during WW2, all the males were called to serve in the army, which left a lot of vacant space that needed to be filled. The women filled these positions, and took over producing war material. After WW2, some women returned to working at home, however many still wanted to work outside. This led to a shifting workforce of dominately males inside the workforce to more of a half-and-half.

Answer:
Explanation:When and why did the world population grow? And how does rapid population growth come to an end? These are the big questions that are central to this research article.
The world population increased from 1 billion in 1800 to 7.7 billion today.
The world population growth rate declined from 2.2% per year 50 years ago to 1.05% per year.
Other relevant research:
World population growth – This article is focusing on the history of population growth up to the present. We show how the world population grew over the last several thousand years and we explain what has been driving this change.
Life expectancy – Improving health leads to falling mortality and is therefore the factor that increases the size of the population. Life expectancy, which measures the age of death, has doubled in every region in the world as we show here.
Child & infant mortality – Mortality at a young age has a particularly big impact on demographic change.
Fertility rates – Rapid population growth has been a temporary phenomenon in many countries. It comes to an end when the average number of births per woman – the fertility rate – declines. In the article we show the data and explain why fertility rates declined.
Age Structure – What is the age profile of populations around the world? How did it change and what will the age structure of populations look like in the future?
